so lately my car dies when i come to a complete stop, it also bogs when i try to take off it feels like its misfiring. lately it seems like its burning more gas then regular. Its not throwing a cel code either, i have read the thread on here about the stuttering and stalling problem but still cant figure it out. So far i have done a map whack, that didnt work i changed map sensors i cleaned my IACV cleaned my throttle body and still nothing. i hooked it up to a obd scanner and says the car is running lean i have also changed the spark plugs. any ideas would really be appreciated thanks

 

 

bump for help

 

Do you have any engine mods?

 

nope just a fujitsubo exhaust, also the motor has about 40,000 miles on it

 

Check your air filter to make sure it's not clogged.

But it may be a case of bad gasoline. Have you run multiple tanks of gas and the problem has been there for all of them?

 

yeah multiple tanks i tried running some fuel injector cleaner in one of em.

 

sounds exactly what i had a problem with. I did a map whack and replaced the map with the new zip tie one, that worked for about 3 months and then i started to feel it coming again. It only acts up very seldomly and usually in hot and humid weather, so i usually just blow it off and blame the weather.

Other than what negcamber has suggested i got nothing =(

If you do find a fix though please share

 

I experienced the same thing last year, it used to happen on a hot day or when the engine was hot and what worked for me was TB coolant by pass. Try the link below, it might help.

Car finally threw a cel p0300 p0301 p0303 misfire. I just recently changed my plugs twice maybe could be bad coils??
