PT. CRUSIER HAS A ROUGH IDLE

2003 Chrysler PT Cruiser

Shakes or Wobbles problem
2003 Chrysler PT Cruiser 4 cyl Two Wheel Drive Automatic 60,060 miles

2003 Pt. Crusier turbo automatic has a rough idle and sounds like a misfire when in park or when in gear at a stopped position. Seems to run fine when in park when you hit the gas or when you are driving. Use premium gas all the time. Seems to take 8 to 10 seconds after you start the car before it starts to run rough. Put new plugs and wires on, didnt help. Took it to the dealer, they did all there tests, couldnt find the problem. No check engine light comes on. Cant find any vaccum leaks either.

Engine running rough or misfiring can be cause by the following-inspect and test all the following below: 1. Defective spark plug.
2. Inadequate spark/coil, defective spark plug wire.
3. Lack of compression
4. False air leakage.
5. Faulty fuel injectors.
6. Insufficient fuel pressure.
7. Contaminated fuel.
8. EGR valve that is leaking.
9. Oxygen sensors.
10. Throttle position sensor.
11. Idle air control valve.
