So i got on it a bit the other day and noticed a pretty good black cloud behind my car. I just figured im running rich so i didnt worry too much, but how can i stop this? I know cars richen up in higher RPMs but it shouldnt be doing it as much as mine is. Also under normal accl the car starts to spudder around 3-3500rpm. But its smooth at WOT. Somedude said it could be an air management issue and i was thinking something in the ignition system. Any ideas? Thanks in advance. =) ---

does it puff during between shifts? If so, a good chance you’ve destroyed some ringlands. A compression test is a good idea to to make sure you’re motor is at least semi healthy. ---

Could be vacuum leak. Maybe the injectors not spraying well… could be a few things. Start with monitoring the O2’s and see what they do through out the RPM range. ---

Well i think i have it narrowed down to an ignition problem I got a new OEM Cap and rotor and its still doing the same thing. The cap and rotor that were on the car were both pretty ugly and should have prolly been done anyways. Im checking the voltage on the ign. coil inside the cap tomorrow. Any more suggestions?
