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

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

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.

This 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

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.


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.

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
