Default Idle problem at red light?

On my 84 vetter the idle SOMETIMES drop to 400 rpm when stopping at light and about three seconds later goes back around 500 to 600 rpm. But when a/c is on and it drops to 400 it dies somtimes? I have replaced both throttle body sensors and both injectors! This helped a lot but somtimes it will still die? Any suggestions? :cheers:

Did you put a different cam in like me that caused that :jester .

It could be your A/C clutch sticking or something. Not quite sure.....

edit: nm.... it does it without the AC on... hhmm... dunno then! Maybe your computer is dying.

What's your voltage drop to at idle? Mine feels like it's going to die now b/c my alternator is going.
