      The check engine light is located on the dash and stays on if the computerized engine control system detects an engine performance or emissions problem.

      First step - have the stored fault codes or check engine light scanned - for free - at any local auto parts store; Advance Auto, Auto Zone, NAPA. Then, post a reply as 'add answer' with the specific code for more assistance. There may be a fault code stored in the OBD memory which may not be displayed as a check engine light.
      There are literally hundreds of possible codes - so this first step is important to begin any diagnosis

      A code P0420 may mean that one or more of the following has happened:
      Leaded fuel was used where unleaded was called for
      A damaged or failed oxygen sensor (HO2S)
      Downstream oxygen sensor (HO2S) wiring damaged or connected improperly
      Damaged or leaking exhaust manifold / catalytic converter / muffler / exhaust pipe
      Retarded spark timing
      The oxygen sensors in front and behind the converter are reporting too similar of readings
      Leaking fuel injector or high fuel pressure
      Cylinder misfire
      Oil contamination

      Technical Service Bulletins (TSBs) are recommended steps and procedures for repairing vehicles. A TSB is issued by the manufacturer when there is a growing trend with an unanticipated problems, but does not warrant a recall.
      Most repair shops and dealers can look up TSB information to get the recommended repairs from the manufacturer.

      A used engine for your vehicle ranges from around $1000.00 to over $2100.00 - minus the labor for installation.

    Intermittent loss of oil pressure
    This car came to me with the oil light staying on intermittently. I check the pressure with a positive (mechanical) gauge. Starting the engine cold the oil pressure is at 70 PSI. As engine warms drops to 40 PSI. However after running for about 10 minutes the oil ...

      I would pull the oil pan and see if the pickup tube has a blockage at the screen and if that is ok I would undo some rods and mains and look at the bearing condition. If you see the copper then that is where the oil pressure is going because after about 10 minutes the oil viscosity thins and flow through the excessive bearing clearances increases causing the pressure drop. Also, there have been cases where a jack placed under the bottom of the oil pan pushed the pan bottom up and makes contact with the pickup screen thereby blocking it. Confirm that is not the cause.
      Thanks, HouseCall. i'm going to drop the pan and check it out. I'll let you know
      how I make out.
