HYUNDAI ELANTRA COIL PACK PROBLEM

2003 Hyundai Elantra • 83,000 miles

In park the engine will idle rapidly up and down, I have changed the TPS and no results, I was told it could be the coil pack, so I took a spark plug wire off one at a time and replaced while engine was running and the car idled correctly with spark plug wire off at the coil pack, so could this be a faulty coil pack, thanks

Try cleaning the throttle plate on both sides as well as iac hole if you have one then if still doing it check fuel pressure and check for vacuumleaks.
