    Whats the location of crankshaft pos.sensor
    does it have 1 or 2 crank sensors

      Your vehicle is actually equipped with two crankshaft sensors. The first sensor is located in the block itself, on the side. For front wheel drive, remove front right tire and wheel. For all wheel drive, disconnect catalytic converter from exhaust manifold and reposition.

      The second sensor is located at the front of the engine, behind the harmonic balancer. For this particular sensor it looks like the harmonic balancer must be removed.

      41-902 shows to be a platinum, about 7 bucks a plug. The conventional spark plug, 41-601 for your vehicle is about 2bucks a piece. I wouldn't use platinum plugs, I'd use the original plugs. Just my opinion.

    Car slows down on highway and then stopped. Restarted but it did it again. Did I get some bad gas or what?
    Husbands car not mine and he can't remember when he had it serviced other than the oil changed.

      As far as your charging system, use a digital multimeter and do some testing. First, you need to make sure the battery has a full charge, all battery connections in good shape. With everything off, the meter leads across battery posts, the generic spec for a full charge is around 12.6 volts. Then start the vehicle, take second reading across battery posts, engine running, the second reading should be higher than the first if charging system is working.

      Also, check for battery drain with everything off, amp draw. Usually shouldn't be more than 50 ma, that is .050 amps, not even a tenth of an amp.

      We can check tail lamps later. Have to check voltage--ground--bulbs and maybe wiring circuit for lamps.

    My car won't start when it gets hot.
    The car gets hot easily and it will drive fine but when I park and turn the engine off to go into a store, when I come back out and restart it , it will start run for a few seconds then act like it's not getting fuel by spitting and sputtering and then it will die. ...

      The check engine light doesn't have to be ON to store a fault code.

      Check the vehicle for fault codes to see if there are any sensors were involved to the malfunction of the engine.

      1.Local auto parts stores such as Autozone ( not in California) or Advance Auto parts will scan and retrieve any diagnostic trouble codes ( dtc ) stored in the powertrain control module for free of charge..

      2. Amazon.com has the code reader for less than $ 18.00 dollars + shipping
      Autel MaxiScan MS300 CAN Diagnostic Scan Tool for OBDII Vehicles

      3.Re-post the dtc's in here " answer question " for further assistance.

      Note: we need the dtc's to identify the sensor, there are a dozen different sensors to operate the car.

      Visit this site and see all the different sensors.
