Drop in to an Autozone, or Pep Boys, or similar big parts store & they will usually scan for codes free. This will hopefully eliminate all the guess work, or at least point everyone in right direction for better diagnosis. If not obvious from codes what the problem is, get back to us and we'll help you out.

SOURCE: engine light code P1507:

P1507 is "Idle Air Control System Underspeed Error". This code indicates a problem with the Idle Air Control (IAC) valve assembly, harness wiring for the IAC or the Powertrain Control Module. So checking the IAC next is the most logical step.

Does it have the 2.3l Quad 4 engine? If so replace the plastic piece that the coils go into, they go bad and leak spark to the cam towers and then you get a nice one or multiple cylinder misfire.

    The code reads P 306 misfire on cylinder 6. How


    A P0306 code means that the car's computer
    has detected that one of the engine's cylinders is not firing properly. In this case it's cylinder #6.

    Symptoms may include:
    the engine may be harder to start
    the engine may stumble / stumble, and/or hesitate
    other symptoms may also be present

    Causes

    A code P0306 may mean that one or more of the following has happened:
    Faulty spark plug or wire
    Faulty coil (pack)
    Faulty oxygen sensor(s)
    Faulty fuel injector
    Burned exhaust valve
    Faulty catalytic converter(s)
    Running out of fuel
    Poor compression
    Defective computer

    If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.

    If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.
