Hello Everyone!
Hopefully someone can help me out. My Z28 is experiencing a surging problem
under light throttle pressure, around 1500-2500 rpm, any gear. The problem
feels worse in the first 4 gears (have a 6 speed) because of the additional
leverage that the engine has in those gears. I have replaced opti-spank
twice already so I am guessing it can't be that. Also, it does not seem to
happen until after the engine is warmed up (when the computer goes into
closed loop). If drive the car immediately after starting it, I don't feel
the problem. What sensors or other parts could be causing this? I even
just threw on a new coil module and coil wire to see if that would do
anything, but no luck.

Please help!!!! Thanks a million!!

Does your car have AC? I found mind did something like this, and it ended
up being the AC needed to be charged up. For me to fix mine, I just
disconnected the AC, and have not had a problem since.

Moose, thank you for the suggestion. My car does have AC, but this problem
occurs regardless of whether it is on or not. In fact, I rarely have the AC
on because I like to have my windows down and T-tops off, listening to the
stereo or the beautiful sound of the exhaust on a warm summer night. :-)

sounds like it might be your mass airflow sensor.... i had the same prob
with my 87 firebird and that was the cause
