thats another thing i live in SC and for two weeks prlly longer high 80's low 90's i cant just imagine what its doing to my engine. i havnt done much research on the seafoam iv read a lil but not much to know exactly how to do it.

this throttle body bypass is it something thats already on the car or something i have to buy? sorry for all the questions.

thanks for everyone who has contributed i really do appreciate it!

just search DIY throttle body bypass and it should come up...I think it's like 5 bucks basically keeps the coolant from flowing through the throttle body so the intake air temp is not so hot.

seafoam is pretty easy too search mazda de-carb and the DIY is there just suck some throgh the vacuum ports on the intake mani. and let it sit in the chambers for an hour or 2 then fire it up and watch the smoke show!

simple order for the issue.

make sure the wires are on the plugs and coils are tight..

that is a known issue.

then check the plugs.

then check the coils.

after that you can dilly dally with the wires.. they really dont fail often.

can they be improved on, yes. but most of the time they are not the issue.

also, op. what flash are you on? that will give us more info to use..

beers

^u do realize that after that statement i said "someone else will have to chime in to verify that"...hence ppl "chimed in" and said no to nology wires....was not sure thought that I've heard of ppl using them.
so technically it was not bad advice because I said "I think some ppl use nology" but was not stating that "you must use nology" because then that would make it bad advice...

swoope

iTrader: (5)

yep,

i saw that..

and all you do is chime in with advice that has been given above all the time..

this is one of the times you quoted something other that what was posted above.. and you got it very, very wrong..

that seems to be how you do things.

so take the time to read and learn the facts, info. or stop just quoting what is above..

learn, help. in that order..

bad advice is bad advice. why should risk someone elses stuff for someone to chime in?

beers

rx8man. thanks for the links those helped out alot. i remember reading the one about the decarb glad to have the link again.



that flash i had to look up lol. i honestly dont think my 04 has gone to see if it had anything recalled. i bought it from a used car lot at a chevy dealorship.
im honestly starting to think i should just put my stock intake back in and go to a mazda place. ugh!!!!

that would probably be the best thing to do...

04RX8man

Thank you but i do know the info and facts on MOST things no I DO NOT KNOW IT ALL!. And I'm sure you maybe once in your life have done the same thing but maybe you're perfect what do I know right? SO if you have a problem with me helping people by also saying what is needed just stop reading my posts....yes I may not know something EXACT like the NOLOGY wires but I will, if I don't know back that up that I"m not sure with saying so. I WILL NOT direct someone to get something that I am not positive is good. Likeif someone writes and says "Ibacked my car out of the garage shut it off and now it won't start" I don't say oh compression check or some obsurd comment I give the right answer which 99% of the time is having the vehicle flooded...

I don't know of any threads that the first post to answer the OP's question is the LAST post....almost EVERYBODY around here will chime in and say "yeah like said above coils is what you need" or something to the effect of that nature!

So, if the case is you don't like ppl that repeat the same answer u better get on somebody other than me for agreeing with ppl that say the correct answer. Becasue I am not just going around he clicking on threads and saying oh yeah he's right. I do know about cars ,ALOT, ihave went to school for it(yes no school for rotaries HOWEVER the concepts of the car/engine work the same way just move a little different inside the engine that's it for the most part).

*Update*

i cleaned my MAF i disconnected the negative side of the battery for like 30 45 minutes.

fired it up and went to bk w/ my gf

everything sounded great today and yesterday i didnt have any bogging or stuttering when i first turned the car on the dsc sign was on and in the corner said it was off. i pressed it a couple of times but nothing happened i shut the car off and then back on and it went away...does that mean its back on now?

still having problems starting only this time when i went to leave bk it really had a hard time. so next friday when i get paid i will buy some spark plugs and see if it helps.

I had this same problem. It was a misfire because i had a bad coil. The misfire caused my cat to get clogged which made my exhaust to get red hot and started my back bumper on fire. But when i brought it to mazda to get the cat replaced they replaced the motor as well.

ok this is bs foreal. i took my car to a mazda dealership because it started bucking really hard and the CEL came on and ***** been going down hill.

I just got a call from the guy that worked on it. he said i need new sparkplugs, coils, wires which i knew that.

what i didnt know is that i have bad vacuum leaks and its dumping raw gas into the cat and he said that if we dont get this fixed it will be like 2k to replace the cat.

after i got done shitting my pants he then tells me the total to get out the door.

here it comes...$651.94

so i knw i can replace the sparks wires and coils my self for like 200.00 give or take

but not the vacuum lines i dont know much about that stuff. so he tells me i shouldnt drive it until i have the money for this.

i ask him have you checked the compression.

he said that until he gets this stuff fixed first he wont do anything about the engine because it would still need to be fixed before he would replace the engine which is understandable i guess.

what about recalls? he said that he would look into that for me before i come to pick it up at 530.

so i knw i can replace the sparkplug stuff. thatl save me some money but damn what a dissapointing thing to hear.

what do you guys think about that?

I recently replaced my plugs, wires and coils. I got my plugs and coils from FluidMotorsports and my wires from works concepts. But you can save yourself some shipping and get the NGK plugs for $19.81 each and the NGK OEM replacement wires for $21.70 for a total of $100.94 from worksconcepts Also, if you spend $100 you get free shipping from them. Then do like what was already said and go to FluidMotorsports for your coils @ $30 each.

As for the sound you are hearing, does it seem to be worse if you are running your A/C?

Guy Hollywood

It sounds like I am having a similar problem with my 8. The past couple of days it seems to turn over a little longer before starting, and today my CEL started flashing and the car started bogging down a little bit. I also lost some acceleration as well even when down shifting. I also noticed a weird smell inside the car. Once I got home I stepped on the gas in neutral and I heard a rattling from underneath the car. Not really sure what the hell is going on. I have an 04 MT and it has about 51k miles. I replaced my plugs with NGk's at about 35k. I use 93 octane since I've had the vehicle which has been almost a year and a half. You think it's just the coils and wires? Cat **** the bed? Something else?

Also, is it safe to be driving it?

dude that sounds exactly like the problem i had.

have you put a after market CAI in?

that was my problem lol i kinda messed up the install haha left some vacuum lines out and what not.

check and make sure your MAF is clean and make sure that your filter is clean. um that marbles in a can sound i had the same problem but when i put my stock intake back in the problem dissapeared lol

im sure some more people will chime in with much better ideas as to what the problem is.

did this just happen? or has it been occuring off and on?

toss the oem cat - get an aftermarket. or have them replace the oem cat if you're still under warranty. Cheaper than having the stealership do it.

NACer4lyf

iTrader: (1)

yeah def. go aftermarket because the "stealership" quoted me at like $2100 for a new CAT??????? i said thats fine ill drive the car till it wont start haha jk

Guy Hollywood

The car is completely stock, so no aftermarket parts on there currently. I will check the MAF tomorrow to see if it needs to be cleaned. Can I get some cleaner at like Autozone? I had planned on changing the coils and wires at some point, so I will probably end up doing that regardless. I hope it's not the cat as they seem to be expensive as ****. What's the warranty to have the dealership replace it for free? And where can I check out aftermarket ones?

NACer4lyf

iTrader: (1)

there are a bunch of places that offer mid pipes, cat delete pipes, straight pipes diff. names all the same thing. fluidmotorsports has em and bunch of other places and check the f/s section also

Guy Hollywood

Midpipes won't pass emissions though right? And the CEL will most likely stay on? What about buying a new exhaust system? Those don't come with replacement cats do they? Is that why the damn stock cat is so damn expensive? Are there no after market cat pipes that will pass emissions, shut CEL off, not stink up the car, etc...?

Rote8

First, change the plugs.
Look at the wires while replacing plugs;
Are the plug wires cracked or burnt?
How snugly do the plug wire ends fit?
Replace any suspicious plug wires.

Still missing?
Buy one new coil.
Swap out the new coil for each old coil, one at a time.
Test for missing between swaps, test/swap the leading coils first.

Guy Hollywood

Plugs were changed about 15k miles ago. I did not change the wires or coils at the time and probably should have. I had the car towed to the dealership today because it pretty much shut off as I got to work. As in I literally rolled into my damn parking spot. We'll see what the dealer says, but I think I'm leaning more towards a clogged or toast cat. Regardless, I am probably going to change the wires and coils myself after getting it back from the dealership. I'm just fearing the cat not being covered by warranty and having to pay a couple grand for them to install a stock one. I wouldn't mind installing an aftermarket one if they were cheaper, but I want to be able to pass emissions, and I don't want a constant CEL or the smell inside the car. From what I've looked at, that doesn't seem possible with aftermarkets.

Sounds like a lot of the same problems I was having. I did a lot of the same things (coils, plugs, wires, etc) had it to the dealer twice w/ bad diagnosis from them both times. Last week it died on me and "rolled into my parking spot" also. Had it towed, this time, it was finally the correct diagnosis..... new engine on the way for me. I really hope this is not your problem, as it is a pain in the ***. Good luck!!!

Rote8

Midpipes are cheap compared to a cat.
My car doesn't stink, and I've been catless for over a year.
I have no 2nd O2 sensor either, my AEM gauge gets the second O2 sensor hole..
Yeah I have a cel, but it can be reset easy, but it comes back every restart.
If I had another O2 sensor hole(for the 2nd stock sensor), my CEL would only come on once in a while.

Update from the dealer:

The cat is toast which he said was due to severe misfiring. He said that Mazda will cover the cat cost which is about $2,600 installed because it would be under warranty. However, he said that for them to cover the cat, I would need to replace my plugs, coils, and wires to show record that it was done. I told him I replaced the plugs about 10-15k miles ago. And he said well they're junk now. I asked if I just bought the parts myself from the dealership and installed them myself would that work? He said no. They need proof that it was done by Mazda. The cost for the plugs, coils, and wires installed is about $770. Am I getting jerked around here or is this claim legit? Will Mazda not cover the cat if THEY don't fix my ignition system? I just hate paying a couple hundred dollars extra for their shitty labor on something I can do myself. Granted, I guess you could look at it as I'm paying a couple hundred dollars to have a new cat installed. Blah, I digress...
