It may be time for a tune up, Replace the spark plugs, spark plug wires, replace the fuel filter, and clean out the throttle body and fuel injectors. If there is an Auto Zone around your area, you can go there and have them scan the car for any DTC codes that would indicate anything wrong with the engine that would cause the bad idle. If there is no code, then time for the tune up and mentioned. Good luck and keep me posted, be glad to answer any questions you may have and Auto Zone can give you the step by step instructions to tuning up your car free of charge too like the scan.

    The PO300 code is random/multiple cylinder misfire detected. Sinsc you have the code PO302, that means that cylinder 2 is the one misfiring, usually a bad coil pack, or spark plug.

    What is the correct placement for plug wirs on a 1999 pontiac grand am se 6 cylinder. i just cahnged the spark plugs but when i sit at a light in drive it jerks. what could be the problem.

    If the wires were connected incorrectly the idling would be very rough while sitting. The very front of the engine starting at the passenger side is 1,3,5
    The side toward the firewall is 2,4,6
    Start from the passenger side on all numbers above. HINT....Also the intake has the firing number by each cylinder
