strange idle issues 94 vette
Just want to see if anyone ever had same issues and what they did to fix or not fix.
94 vette 214,000 miles have new opti, coil, ICM, TPS, oil sending unjt
at low idle in gear vette misfires and surges badly, in park the idle is much better put still surges. service asr light is on.
When I drive in OD and stop at light the surges and missfire are bad like I stated above. put if i drive in "D" the idle is much smoother and surges is bearly noticable.
Fuel pressure ck was good. any ideas
TPS
IAC
Injectors
ECM
also when cold oil pressure is great at operating temp oil pressure is much lower at idle, below 10psi
ANY ideas

Have you pulled any codes?
Have you removed the throttle body and cleaned it and the IAC and orifices?
