Same issue as before - it might be just that the used idle air control valve I got was bad, too, but it just died again, no codes. When it died and wouldn't go again on Sunday, it finally threw a P1504. Just the code that one time, not before, not since. When I swapped in the other IACV, car ran a little better than before even. Ran really well for the last two days, actually.
But, runs great, idle dips (or throttle cuts out), then it just dies. No codes.
I don't want to keep throwing parts at it, and obviously my diagnostic skills suck wind like dying man. Who else has had it drop idle and die with no codes?
