#342759 I adjust the idling screw but it keeps dying down when I take it out of gear if I adjust it then it moves again by itself and it will either idle high or low the screw just will not stay in place :?

#342806 Describe your process for adjusting the idle screw.

Your car should be at operating temp with all electrical loads turned off, ECU jumpered, and you should have an accurate tachometer (not the cluster tach).

Ignition timing should be dead on.

#343917 cracked vacuum hose? bad IACV?

still need more info to help. Plus, if you adjusted the idle screw without jumping the ECU, you pretty much need to get back to where it was before you jump it and try again... if that IS the issue.
