    My book doesn't list any codes starting with A. Sorry. But the high side circuit may be in the A\C system.
    The 091 says PRNDL switch problem.
    098 says High RPM P/N to D/R shift under ISC.

    Going off what is being said-091 code PRNDL- the computer is not seeing the correct gear selection coming out of the PRNDL switch. It could be out of adjustment, this isnt that bad. The 098- high rpm is the computer seeing a high rpm reading when you select a gear from park. This is usually caused by the ISC motor being bad. If you said you noticed it running at high rpms, this could very well be your problem. Get yourself a factory shop manual. Hynes/chiltons are no damn good. There are steps for replacing the ISC motor- more than just replacing it- You need to let the computer relearn the settings.

    Re: 92 Eldo Problems

    FYI to all of you.

    The E091 - PRNDL switch problem
    it has effected my e-brake. to disengage the ebrake your supposed to put the car in gear. I did that and it doesn't come off i have to manually do it.

    The E098 - High RPM P/N to D/R shift under ISC
    It has effected my idle. My car stays at a constant Idle for a lot longer than it should

    The A011 - high side temp circuit
    This could also be effecting my idle

    Anyone know how to correct these problems that would be much appricated. I am soo lost on these problems and i can't afford to pay a garage.

    My 91 Deville had the same problem, turned out to be the idle speed control, the thing would get hung out, and keep the idle high? Maybe this will be some help, don't know if they are the same motor or not.
