diy to clean throttle body?
 

is there a diy to clean the throttle body?

thanks

1. Remove throttle body
2. Clean Throttle Body
3. Put Throttle Body back on.


Done.

I see some philips screws around the throttle body, is that all I need to lose besides the electrical plugs? Like when I remove the MAF?

Btw my mechanic said something where when one cleans the throttle body the car may not start after:Wconfused

just remove, clean, put it back on.

seriously, that's how simple it is

just don't force anything ... u need to take 2 coolant hose clip and 4 bolts (itS NOT philips screw) off and that's it.

oh btw, u should replace the gasket after ur done,

That's not a thing.

You don't really need to replace the gasket unless you damage it by trying to pry something off.

after all the years of heat cycling, once removed the gasket will not seal well, hell after fixing couple dozens of rx8, some of the gasket just give up and u can see traces of dust going thru it before I even touch it.

just replace it, not like it's expensive.

Ok I am gonna attempt to try to do this without a torque wrench, just a screw driver. I can't replace the gasket now. Dont really have the money to spend on someone fixing it and my mechanic is super duper swamped with cars. So will try to do it tonight. Will report back. Hope the car doesnt have problems trying to start after cleaning.

If yours has screws then:
1) Something is f'd up
2) We are not talking about the same thing.

Here read this ----> Clicky https://www.rx8club.com/series-i-do-...-part1-167033/

It provides you with what you are looking for even tho the OP in that thread is installing the BHR TB spacer.
You likely only need to read to #4
But look at the pictures.

Shouldn't even have to unbolt it. If its like every other throttle body just, pull the intake off, hold the flap open, be liberal with the carb cleaner, and wrap a rag around your finger.

Or this sure.

My question is why does the OP feel he needs to do this in the first place?
Especially when the OPs knowledge on such things is at best ... limited

I'm hoping the OP isn't referring to the screws on the butterfly.

YIKES.

Jinkies Scoob let's get out of here!

No yes this is the part I was looking for in the engine bay.

Thanks for your post and help. I am trying. I originally used this video for reference.


I unsnapped the air filter container. I see that. Then there is a long hose in front of it which connects to the MAF sensor I cleaned last week. I took off the electric plug. Then I moved up and saw another screw which I loosened and then removed and tried to wiggle that whole connection. (No dice). I wasnt sure which way to pull to get the air filer container up. No budge. Also the biggest thing that bothers me is I see NO way to crank the throttle open. The up and down switch he cranks in the video. Nah-uh. I looked all over the place. Maybe hidden somewhere I am not looking. Black extension tubes everywhere near the throttle body. Thoughts?

Thanks though everyone for the support. Learning more each day. Doing my best to avoid finding another mechanic, mine is booked to next week and everyone else is asking ridiculous prices. $150-250 bucks an hour.

My engine light is coming up continuously, went to my mechanic a a couple of weeks ago and hooked it up to the reader and it looked like something was up with the MAF. Cleaned the MAF properly and now going to try the throttle body. Plus the car "idles and shakes like hell when I stop at a light. I know it could be another issue within the engine I forget the part but this is has been an effective and money saving step for alot of people I heard. Plus I dont remember the throttle ever being cleaned.

IF I get what your saying your referring to the air intake? Removing the MAF sensor plug. The two air intake clips. The screw that holds the clamp(unscrew) but then what? And how does one remove that part? Pulls up?

That guy in the video is working on a Toyota with a throttle body that has physical linkage to the gas pedal.

Your RX8 has no linkage it's an electronic throttle body (like fly by wire)
The only way to open the butterfly is to gently push on the outer circumference of the plate.


I would check the motor mounts. Very common problem with the early RX8's

Not to say the Throttle Body doesn't need to be cleaned but motor mounts are known issue as well


No, he is talking about the two screws that hold on the brass butterfly plate inside the throttle body.

I see like in the picture you posted.
https://cimg4.ibsrv.net/gimg/www.rx8...3d01b31dda.jpg

I will research these motor mounts. Not sure what they are but going to look around.

But again the removal of the air intake and then within the "black tube" under the MAF is that going to help to see the TB, where one can spray the TB? I noted you mentioned in the video I posted its a totally different setup but the Rx-8 has no way to turn the TB? As long as I can get in there and spray it and wipe it clean. I really dont know how to take off the air intake. I dont believe it is one piece with that black tube under the MAF.?

Man the manual really is terrible with information on this.

Your throttle body is not the problem. Let's start from the beginning, what actual code is it throwing? What does 'idle and shake like hell' mean? What other symptoms are present?

Asfor removing the air box. Remove the clamp from the tube on the throttle body, remove the maf plug and the vfad plug. Leave the air box snapped closed. Then grab the back of the airbox and pull up. it will snap out of place and the hose will pull right off of the throttle body. lift up and remove the vac hose. then set it on the ground and you're all clear.

I honestly dont remember the codes because my mechanic was the one to hook it up to the reader like 2-3 weeks ago. But for a while now the engine light has been on and the car shakes when not moving. I'll be sitting in the car and it will really rumble. Not really sure if when I turn on the A/C it might make it worse.

Thanks, I'll try this next.

Oh I missed that you still have a check engine light on.
+1 on what Loki said, you better get that read so you know what the ECU thinks is wrong.

Stop advance auto or wherever. They'll read it for ya

So...I just went to get the throttle body cleaned. I am amazed at the new way of doing it, with like an IV setup. One thing that was on the reader the code P-0661. I looked that up apparently it relates to the Intake Manifold Tuning Valve Control Low Bank 1a

Ummm wrong:

P0661 - SSV solenoid valve control circuit low

You'll wanna get that looked at, the SSV is very important.

Use this thread to look up codes:
https://www.rx8club.com/series-i-tec...n-guide-26291/

And here about SSV diagnosis

Thank you for posting. I tried to do my homework.

https://www.rx8club.com/series-i-tec...ank-1a-239579/

I guess I will be getting it checked out soon. I am looking up more info though anyone have any more feedback on this? Thanks in advance.

Ummmm again this:

go to another thread then because this one is complete BS as pointed out by nycgps

the OP is using a generic OBD2 code reader which does not provide the correct info and is the only one responsible for blah-blah-blah cluelessness

That thread doookie

rx8 ssv solenoid connectors
 

i just replaced the three solenoid connectors the blue white and black ones with dean's connectors and all is good now the factory connectors suck and where corroded cut off all and solder on new wires to the the solenoid with dean's and solder dean's to the wire harness

How much did it cost and how long did it take to do if you dont mind me asking?

about 15 bucks for all three connectors and about 2 hours its really easy just take off the upper intake manifold off to get to the solenoids and wire harness

Versus cleaning the SSV? How long is that in comparison?

Removing and cleaning the SSV could take 4-6hrs depending on the person and their knowledge/comfort level.
Since the CEL was solenoid related, that is where I would focus.

Though you can test the SSV to see if its stuck. Here is that DIY:
https://www.rx8club.com/series-i-do-...valves-174009/

You can also test the solenoids using the DIY below, but solenoids do stick open/close so this method is harder to distinguish solenoids sticking.
https://www.rx8club.com/series-i-do-...lenoid-190364/

don't know but if you take off the upper intake manifold you can clean the ssv to

code P-0661 is for the solenoid for the ssv and other valves there are three i took off all and tested them and only one worked but after cleaning the contacts and the new connectors they worked fine my light was on but after cleaning and resetting it's off and been off for a while now so if your ssv is not stuck and your rx8 runs like a lawnmower it's the connectors

Provided the key is out of the ignition, can I clean a throttle body (including moving the butterfly valve by hand) with out screwing anything up? Supposedly it could cause the car to idle poorly (to high or to low) don't want to have to get it relearned.

If it idles poorly after cleaning the TB and nothing else, that means you dropped something into the engine and ruined it, don't do that or you'll look really stupid.

The car relearns anything whether you want it to or not, it's not a big deal.

F***! Just found out its going to cost me $800-900 dollars to fix. All three solenoids have to be replaced.

They do? That sounds fishy, how do 3 solenoid fail at the same time?

When the day comes where you actually have to clean/free a stuck SSV, let us know how that method works for you.

Only the SSV solenoid would need to be changed (which is the solenoid in the middle).
If you are running without a catalytic converter, you can swap the AIR and SSV solenoids (AIR is the upper solenoid).

Dont really know to be honest but freaking $110 dollars an hour to check it out and then the parts and then the labor. Came out to like $800-900 dollars. Nuts. Still have a slow leak tire, an oil change and the ignition teeth sucks. Not to mention the engine shaking which makes the whole car rattle at stop signs so the engine or transmission mount may be a later issue.

+1 with Loki

What do you mean ignition teeth?

Motor mounts are a common issue, will cause a lot of shaking.

Do you mind posting exactly what they charged you for? Because it sounds like you're going on a ride, half of these things don't make sense.

They had to look at it which took two hours.
They had to order all three solenoids.
They have to install them. They said its a 3-4 hour job.

Edit: Not sure if its all three they ordered. Thats what they told me, they got me down for a throttle gasket and a intake gasket and a solenoid part. The 3-4 hours of labor will come this week too. Does it really take that long to do? $24 dollars and 8 bucks for a gasket? $ 300 and change for 1 solenoid part?

lol, it's a 2 hour job at most for a dealership, but they are probably charging you book time.

IF you have a small arm. You could Just pull the oil filter then reach your arm around and replace them.

Yep heard about that. Yes I meant the ignition teeth the newer models have more teeth which makes the ignition start better. At least thats what I heard.

I dont know, its out of my hands now cause I am a newbie with my car, dont really know anyone who fixes mazdas( my mechanic hates them) and the dealership I cant tell them what to do. I saw the repair dude he is a big guy no small arms so maybe thats why. Oh they said they had a problem getting past the intake manifold to get to the third solenoid.

Oh. Huh mmm
I know the Series 2 starter is a direct fit in to a Series 1.
The Series 2 starter is a bit bigger in size, is a stronger faster starter.

I don't believe the Series 2 starter has a different engagement gear (worm gear) or that the tooth count is any different between the starter rings between the two series.
But I don't know , I've never checked or cared to find out.

Well most dealerships charge book time. Which means they have decided that Wort case scenario is will take 4 hours to do this job. So they bill 4 hours for the job. Then if they do it in 1 hour they still charge you 4. If it takes them 5 hours for some reason. They'll charge you for the additional.
