Have a 2003 Pt. Cruiser turbo, use premium gas all the time. Has a rough idle when in park or in gear at a stopped position. Runs good when your driving. Seems to take about 8 - 10 seconds. after you start the car before it starts to run rough and sounds like a misfire. No check engine light comes on. Brought it to the dealer, they checked the computer for any codes, and did all there tests, nothing came up. They couldnt help me. Changed the spark plugs and wires, didnt help.
