I have started a few threads and got help from some of you.
I have had the coils replaced, intake put back to stock from aem, replaced spark plugs, flushed transmission fluids, replaced gas cap and my car still idles rough and runs like crap

the car bogs down bad

i dont know if its the engine or transmission or what
but im pretty much over it
im bringing it back to mazda tomorrow

mike, which dealership are you taking it to? Have they done a compression test?

had the same problem and took my car in, i had a burnt leading coil which u say you replaced but i also had a leak and my cat was all fuc*ed

ever since i picked it up its been running badass, i even put in a K&N intake

i have not had a compression test done
and im using tustin mazda

i will have the cat looked at
im about one day from selling the car

mike: Bob took over as the Parts and Service manager at Tustin recently (Jennifer is now at HB Mazda since it was purchased by John Patterson)

He's a reasonable guy, convince him to look at the cat and do a compression test.

i was uste to gil helping me but i know he is gone now
not sure if he left mazda all together or not
the guy that is suppossed to help me is kory i guess

When did Gil leave?? I liked him but he was kind of scatter brained. (for some reason, he's always forget to add things to my service order) :)

I think I dealt with Cory once, but don't really remember. Either way, talk to Bob if you can. He was a forum vendor here for a little while, I think he'd signed up as OCmazdaspeed or something like that. (when he was managing the parts dept)

I was down there yesterday picking up some crush washers when I heard that Bob had been promoted. Hopefully they can figure out what's wrong

Mike that is so incredibly frustrating. I feel for you. :mad:

I had a slightly similar problem to yours (I think you're a manual, though, and I'm auto) and my entire engine is being replaced. I know you're not under warranty so that's not exactly an affordable option for you...

Mikeb = A/T

well if its the whole engine i may be over this car
but it was in service last week for cel and they didnt say shit about the engine or cat

they just said it was the coils
we will see probably by tomorrow

You really have to ask them to do the cat as its a pain in their collective asses. I had similar issues, although my car was an mt. I've had the cat, coils, plugs and vent tsb performed. The car is perfect now. Mine had all those go bad in 11k from new.

mikeb.

with your join date i dont know how you dont know what is going on..

you are the king of likely motor failure.. if getting a new motor puts you off the car so be it..

but it will fix the problem you have been dealing with..

beers :beer:

swoope
your right
i have had the car since the beginging of time it seems

it is being looked at right now by the dealer
its out of warranty
i have 67k miles on it

i dont want to spend a few thousand on a engine
how do i know it wont happen again?????

hope you get it resolved mike!

good luck man. I didn't realize you were out of warranty....

i also did not know you were out of warranty.. but it is a recall so you might have some leverage with mazda...

the last flash will keep it from happening again.. or so they say.. :)

beers :beer:

I'm willing to bet that if it is the motor, that Mazda will replace it, warranty or no warranty.

Keep your hopes alive

I sort of hoping the motor ends up being the culprit. (because it'll be FREE and hopefully fix all your problems)

Any update? haha, don't make me call Tustin Mazda and find out on my own... :rofl:

thanks guys
i did get a update
they BELIEVE it is the CAT
and they are trying to get it done under warranty
i guess the compression test showed some problems with the cat or something

cat warranty is 100k miles

they are replacing the cat for free
but i guess they have to order one
why cant they have the cat IN STOCK

got the car back
thanks everyone
i got the cat replaced for free

the car is better but seems to still not be 100 percent
i put the stock intake back on but the car seems to really have trouble at high rpms or up hills

i give up

check the little things mike:
-plugs
-coil packs
- clean intake

sorry to hear you're still having issues.

jedi
i know right

i have new spark plugs
stock intake
new coils and cat

i just dont get it

damn...WTF?!
Maybe they reset the ECU and it'll just take a few drive cycles to smoothen out.

^^^^ thats what im praying lol

Did they do a compression test with the new CAT?

i dont know^^thats my fault
i pretty much walked them thru the problems
first i said coils so they replaced them
then i said cat and i belive teh compression test showed the cat as the issue

the car drives about 80 percent better , it does
but i cant hardely make it up a hill

ok guys please offer some help

so i have a new cat, new spark plugs and coils
the car is running very hot

i removed the coolant cap and it was smoking
why is my car running so hot

you removed the resevoir cap from the car while hot? i assume by smoking you mean water vapor coming or steam coming out. it will do that, as when you release the pressure from coolant system, it will lower the boiling point, causing water to conver to steam.

do you know the results of the compression test ?

i didnt get the results from the dealer
they just told me i needed a cat and replaced it
but the car still doesnt run right uphills and when i hit the gas hard
