Hey guys need some help here having problems with my lt1 t-56.
Car idles like crap very difficult to drive off the line without riding clutch because the car wants to stall. Idle jumps from 1100-500 and keeps jumping, started after replaced the opti, also replaced IAC, water pump, throttle position sensor, coolant temp sensor. And when I drive the car WOT CAR RUNS GREAT only idle is f'ed up and when I'm gear it dies down roughly, kinda sick of replacing everything can't figure it out, I don't think its the opti cause it runs great got power just idle is crappy, thanks for help.

I had this issue after cleaning my fuel tank with sea foam, once I changed the fuel filter it continued to do it most likely due to air in the line while the fuel filter gets fully saturated. Maybe try to replace the fuel filter and priming the fuel pump a dozen or so times by turning the key to the on position. unplugging the battery for an hour or so to let the car relearn idle speed may also help.
Just trying to suggest small cheap things to try before going another route.
