Idle drops when revved
So I hope I can get some insight.
I just rebuilt my lt-1 with stock internals.
Idles amazing but when revved the idle drops a few hundred rpm before it revs.
I do not have any vaccum leaks.
It's speed density.
All sensors are connected.
Thank you1993 Black Camaro Z28. Mod list: Aluminium Radiator.

You need to get a real time scanner on it and see what's going on.

Thank you both for replying.
Turned out to be a short in the wire from the PCM to the iac and a bad tps (no voltage change with position movement ) even though I just replaced it haha1993 Black Camaro Z28. Mod list: Aluminium Radiator.
