ok i have a 94 camaro with a 385, fully built, tti front mount with a 76mm turbo, its a 6speed, new opti. ok. tonight i was driving home and ev erything has been perfect up till now and the car started sputtering, missfiring, or something. i could fell and hear it. it felt like i was running out of gas but wasnt. my fuel pressure looked fine, on my gauge and a/f seemed ok bout 13.5 cruising. well the stumbling/missing started geting worse and when i let it idel it backfired a little, and wanted to die, but i gave itgas and it didnt. got home and it died and wont start. wtf!!!!! i have noticed it taking longer to start also, turns over more than ussual. what do yall think?

 

check your knock sensor, that could cause the timing to be retarded greatly. Also check your tps switch. If these are old parts you may want to look into rplacing them anyway as preventative maintenance.

 

ok i went and got it started today, but i had to hold the gas pedel all the way down and it started, it seems to be smoking a bit, and it is pullin a little less vac than ussual. could fouled plus do this, what bout o2's?

 

dang no one? thought i would get more response here!
