i was reading your signature and noticed what you added to your car. I think it could be some sensors like the oxygen sensors or your mass air flow sensor. Anyways, maybe your car is bogging due to one of those sensors going bad. I just had to replace two oxygen sensors (one by the intake manifold and the other by the cat) and the MAS (mass airflow sensor inbetween the intake piping).

That's just what happened to me tho. Just make sure you don't pay too much to get your car analyzed.

 

There have been people that have said they heard this sound when they put 87 in there. Not saying that some people don't hear it when they put it in, or that their car doesn't run perfectly fine. But i'd rather exhaust most of the things i could try before having to really take it to mazda and get upset with them when they say again there's nothing that they can find wrong.

 

well it was free for them to check why not?.. and kiken how miles in did u have to do that.. cause this catback and high flow have easily less then 2000 miles on them? or their really isnt a time limit to it?

 

well this morning i was driving i floored it and then the engine light came on and was this funky smell. so i took it into mazda...
They said i got some water into the air flow meter and i burned it out.. could they of cause the stalling earlier that week?

 

ask them how the h20 got there, and it the maf burned out. i doubt the car would run.

beers

 

if i remember right they said i suck up the water from my ms cai

 

bullshit.

beers

 

maybe, all i know they said i got "moisture" in the air flow meter, btw i didnt burn it out it was burning out,

 

well i dont think its that. my CAR just DIED AGIAN in the turning lane of a intersection and then we moved it across a good way and started agian istantly.. what a peice this is, time to take it into mazda, this 4 sur means another broken wankel!!!

 

The Cat is bad

 

i would mazda dealer would of check that the first time i took it in, and then my mechanic didnt notice anything either.. but o well to late im driving a 350z now.
