1997 Chevy S-10 4 cyl Two Wheel Drive Manual 300k miles
I recently replaced a leaky fuel injector, since then my truck has an oddly erratic idle. A small 1-200 rpm bounce every second, barely noticeable, I didnt notice it, but the smog guy did when the service engine soon light came on in the middle of the test, so he wouldn't pass it. So I read a little on the Idle Control Valve and how when disconnected the PCM has to relearn the correct idle. Is there a procedure I need to imply or should it relearn on its own. Would that even contribute to an rpm surge?
