    Hello! High idle is being caused by one of two items...A faulty Throttle Positioning Sensor or loose worn throttle plates...As soon as I receive vehicle information, I'll send a test procedure for the TPS...
    Have a look at the throttle plates...move shaft in and out to test for play...Should be very little...

1999 mitsubishi montero sport. Randomly started hesitations and low rpms in gear at idle. and highway speeds dropped rpms slightly and when let off accelerater rpms drop too quick and low. Any ideas?


Engine light on? Many things can cause this. Mass airflow sensor, throttle pos. sensor, cam sensor, idle control valve, O2 sensor, vacuum leak etc, diagnosis be great. Good luck

04 buick rainier, charge light goes off during high rpms


have the alternator bench tested for problem in regulator or rectifier. check and adjust the drive belt. Charge light should go off at at idle and remain off during whole of engine operation
if they come on at idle it means that the alternator is not producing a charge current and needs attention.

1996 Jeep Grand Cherokee. When I stop at a light engine revs up and feels like it is trying to push the car. Then the car dies.It will start back and run fine after that.


Could be a sticking idle air control valve, or dirty throttle body.
The computer uses the valve to control idle speed by regulating the amount of air into the intake.

I cleaned out my choke with correct spray and now just replaced my idle air control sensor but the car is still


You are equipt with a idle speed control motor.There is no way cleaning is going to clear it,When the RPM jumps it is either working and trying to compensate for a vacuum leak.Have the vehicle running as it jumps up and down feel the EGR is it hot to touch? Becuase that can cause the jumping RPM,Check the PCV valve with the car running plug it does the RPM stabalize? If it does replace PCV. You are searching for a vacuum leak

99 Jeep Grand...Idle up and down and now a check engine light


Sounds like an air leak somewhere after the air filter chamber.With engine idling spray some carb cleaner at different areas along the intake hose and the intake manifold,any place air can get in.If rpms change you have found leak.

Myservice engine light came today rogh in idle at light rpms seem a little high this is a 98 saturn sl2 I think engine is a 1.9


the check engine light means that a code has been set. the code will reference a faulty system that must be diagnosed and repaired. sorry for the vagueness, but there are e gads of codes that can cause the rough idling

most aftermarket parts places will scan the car for free. this will give you an idea of where to start.

1991 VW Cabriolet runs rough during idle


Check the hose between the inletmanifold and the pipe to the brakeservo it normally gets old and a crack in so the engine sucks false air on cylinder 4, causing engine to run rough or uneven.
