Engine Mechanical problem
1995 Kia Sportage 4 cyl Four Wheel Drive Manual

Engine accelerates up to 3000 RPM at any shift. Have change the idle speed control valve twice but problem continues. Engine runs perfectly normal and suddently accelerates. Sometimes by kicking the pedal it goes down to normal and there are times I have to turn off and back on for the engine to idle normally.

Do you
have the same problem?

I think your throttle cable is sticking. I would check that. Along with that check the butterfly on the throttle body for evidence of carbon build up and also your throttle position sensor. Idle Air Control only control idle speed, not driving speed.
