Question about 2000 Jeep Grand Cherokee

1 Answer

Engine Hunting When I start the engine it races before idling and rising again and when I stop in traffic the engine revs from 600 RMP up to 2000+ RPM. It is disconcerting as it is trying to drive all the time and it can't be doing the gearbox any good. I think it might be an air leak on the vacuum, but I can't see anything obvious. Do you have any ideas. Regards, Mike Jarvis

When i start the car the engine racces to 2500 rpm why?


This is normal idle control strategy, it races up to keep the engine from stalling out until it stabilizes, if it doesn't drop back to normal idle speed of about 600 RPM after a few seconds (longer on cold start up) then you need to have the electronics tested to see what the problem is.

My 01 Accent cuts out on me when I come to stop and dash board lights up. But vehicle starts up with no problem. What causes the car to die?


It may be that the idle speed of the motor is set to low.A stick shift should idle at about 600-700 revs,an auto at about 750 revs.If the air con is used there is an idle/up device that brings the revs up a fraction because the air will make the engine idle slower.the problem may just be a small adjustment.Hope this helps
