2000 sunfire revs up and down when below 2000 rpm????
i have a 2000 sunfire that revs up and down when below 2000 rpms. ive changed the intake manifold gasket, injector o rings, IAC valve, and the map sensor. and still no change any ideas??? thanks
loping idle is a symptom of plug wires.
the car doesnt miss fire at all tho.
They usually don't at higher RPMS.
the car has a 2.4 liter engine so would it be the electronics under the cover on top of the engine since it doesnt have plug wires??? thanks
You'll have to test each coil plug for resistance. I sent you instructions in a message.
ok sounds gud thanks
The nut that answered this question meant to send it to another question oppps
