Again just keep an eye on it and see if it happens again there are two possible casuses one the sensor(most lilely) and the harness that goes from the sensor to the body harness, you can do some...

    C1225 RF Excessive Wheel Speed Variation

    See if the code comes back it will set if the brake control module sees more than 13mph difference between wheel speed sensors seeing how you did a burn out it's very possible that the rear tires were going more than 13moh faster then the right front and cause the code to set if not in most...

    Camshaft replacement

    Can you do it your self at home with out a lift, yes but you will need a good jack. It realy helps when tring to do it correctly to remove the oil pan when removing the front timing cover. You will need a puller and installer for the balancer which will probably also need to be replaced(at that...

    The 85 EGR temp. sensor is on the EGR valve 86 to 89 sensors are on an EGR crossover pipe the runs from the right side exhaust manifold to the intake but 85 used iron heads which have an exhaust cross over in the heads so all that was needed was ports in the intake to pull exhaust gases into the...

    reverse problems

    If your car is slipping in reverse but not forward it would be the direct clutches in the overdrive unit. The overdrive unit has a sprag gear in it(which is a type of one way clutch) which will alow torque in the forward direction through the unit which helps with shift feel when the unit goes...

    10-PCM P0410HC Air System-B fault

    There will be very little air flow from the air pump and seeing how you are feeling pulsing from the other hose is a good sign that the check valves are working(at least one of them) which means if one was restricted a P1415 ot P1416 would have set. Again your problem is vacuumn and has to be...

    10-PCM P0410HC Air System-B fault

The nuts for the bolts the hold the battery tray down are a type of wire nut that clip onto the tray. If the bolt is spinnig and not loosening that can be a problem I just don't know if you would be...

    Creaky coupe roof -any fix?

    I think you will find that most of the creaking noises you get out of a C5 roof up front is coming from the little rollers on the stricker if you remove the top and look at the stricker you will see a little roller that helps reduce friction when latching the top if you get a can of oil put a...

    10-PCM P0410HC Air System-B fault

    You said the previous owner had the battery replaced I suspect it was replaced for leaking acid I suspect you have a problem with vacuum lines under the battery there are three vac. lines that run under the battery tray one coming from the back of the intake over to the vac. canister(behind the...

    Is this possible?

    I would have to agree with most here I suspect the guy doing the job did not clean the front and rear surfaces correctly any oil left on the surface will keep the sealant from adhearing to the metal surfaces. I always use acetone and a clean paper towel for the final wipe to insure there is no...

    1987 Heater/AC fan

    That would be the C68 system now what you need to look at is the air from the system coming out the vents on the dash or is most of the air going up to the windshield. The modes are controled by solienoids which control vacumn to the door accuators if you loose vacumn into the car they can not...

    Idle wanders

    It would be helpfull if you could get a hold of a scan tool and have a look at some of the data. Block learn and Integerator, O2 voltage and TPS. I suspect the problem lies in a slow O2 sensor, when the O2 sensor gets old they slow down and don't respond quickly and with the slow ECM on an 85...
