RPM surging

Cold engine/open loop ok. Warm engine/closed loop not ok. Likely to be a bad temperature sensor, 02 sensor, etc. Even if the check engine light isn't on, flash for codes. Sometimes an error can be present without the light being on. https://camaroforums.com/forum/82-92...d-codes-20385/

How long has it been doing this? I see your engine is not stock. The cam in that engine is much bigger than a stock TPI cam. You may need a custom chip

Are you really trying to help?? Every post I see from you your selling a d** chip. I swapped my 2.8 to a 383 and it runs fine. Guess I still need a chip too huh?
