hey guys, my 94 camaro z28 started staling the other day and stopped all on its own but is now running rough...the exhaust smells like gas and it was smoking a bit... it feels like its missing alot of power too. it wont go past about 3500 rpm when i drive it...any ideas toward whos to blame?

-it has a k&n intake no cats and a flowmaster muffler with 3' pipes auto with a shift kit.

 

sounds like the opti

 

well i checked and i have good spark at the plugs. it very odd the computer doesn't read any errors either...its driving me nuts! could the intake body need adjusting?

 

Well my mind goes to something like a bad opti, o2 sensors, or something else that would send a signal to your pcm to adjust your fuel/air mix and timing. Where its not doing that, I am curious if its something easy to over look like low tranny fluid. Not sure about the smoke out of the exhaust though.

 

i checked all the fluid levels they are all good. its a scooby mystery! lol i am going nuts! could it be fuel related...

 

If your acceleration has been affected, saying that it wont go over 3500 rpms and a major loss in power makes me think of some catalytic converter problems. Maybe getting clogged, who knows.

Oops didnt read the first post fully. :-p

 

^^agree plugged cat, 02 sensor, ignition modual, air cleaner.

 

Haha Craby I thought the same thing about the cats. Then I realized in the first post he says he doesn't have any :-p

 

lol i thought the last line was his sig so i didnt pay to much att. to it.

 

well if it doesn't throw a code, you would think that would eliminate the o2 sensors or ignition module. What about the EGR valve???
