I have been chasing an idle miss. It randomly stumbles while idling, open or closed loop idle does not affect it at all. As soon as I touch the gas, all is well. At 800 RPM there is no problem. At 700 RPM its pretty bad.
I have replaced the MAF (I have an extender)
coil pack, coils, wires, plugs.
ECM
plugged all vacuum lines, no change
I checked the cam sensor, nothing loose, tried turning it a little, no change.
I pulled the intake last winter so I tightened the bolts, no change.
I don't have a spare crank sensor, could these symptoms be caused by this?
