i am having problems with mycar dying whilecoming to a stop sometimes. this is intermittent can be hot or cold. now, i cleaned the iac a couple years ago because i though it was bad but it turned out to be the pip which was my first suspect but ignored on advice from my mechanic. anyways, im not gettina a cel for this problem. when it does this, it seems to be running poor and using more gas. when it died in the driveway i could smell gas for a second. just about the only thing not replaced on my car is the tps and the iac, although ive also experienced bad new parts and had to replace them multiple times. so i dont know if it is a new part gone bad or an old part. a few months ago i got a check engine light when the car wouldnt start but i finally got it started and havent seen it since. someone told me that there would not be any stored codes after 3 continuous cycles without the problem. is that true? it seems like hardcodes would store even after . i have a chip and i always get a 311 but i do not have a light on. please help
