Z28 Crossfire won't idle

howie69, Apr 27, 5:59pm
I have an 82 Z28 with the crossfire injection. First of the GM fuel injection. I have rebuilt most of the fuel system. New throttle bodies, air control, injectors new computer and a new low volume Holley fuel pump and still have issues with idle. Damn it varies in idle speed between 1k and 1500RPMmay change to carb. Has anyone done this! I am unsure what the computer drives in the electrics. What else could I do, No don't want a Ford already got one. Any helpful suggestions welcome.

Checked for a vacuum leak!

As above use some of that engine start sort of stuff or even carb cleaner/ injector cleaner and if the idle changes while spraying around intakes etc you know where the problem is.

Vacuum leak or AFM or bleed valve adjustment.
