I have a 96 z with long tubes, slp cai, 1.6 rollers, zex nitrous and custom plugs. I have just replace the opti, plugs, wires, and ignition module to remedy this problem but it didn't help. any other suggestions??? Please Help!!!

 

You need to give a detailed explanation of the problem you are having.

 

ok, @ low rpms it feels as if the car is running off of 4 or 5 cylinders but after i punch the gas it jerks and feels like normal. also it seems to do worse after the motor warms up. It idles really rough and it keeps doing that until I give it a lot of gas.

 

Any codes?Did you repace your coil and coil wire?Or the O2 sensors?Those would be my first guesses.

 

well, I did a conversion about 6 months ago to obdI and the coil wire was replaced with the spark plug wires. I didn't think it would be the coil because of only 2 or 3 cylinders dropping. That would be the next thing i replaced though. I also unpluged the mass air flow to send it into air density mode to see if the mass air was the problem.
