    Removed 5qts of transmission fluid, added 7 qts of engine oil to the engine oil pan. Drove 20ft. Please advise
    Transmission fluid pan has the word oil on it and while attempting to change my oil I drained the transmission fluid. Thinking I had drained the motor oil I then changed the oil filter and put 7qts of oil into the motor oil pan, NOT the transmission. Started the car ...

      Not sure of any damage. Simply refill the transmission fluid - and check the operation, as the next steps. Make sure the transmission goes into gear and shifts OK.

    Oil appears low on dip stick, then later, after driving, is OK . Later again, is very low on dip stick.
    Can there be a blockage in the oil circulating system. Have just bought this car so knowledge of it is sparse.

      First question - what is the engine oil level, with the engine cold and parked on a level surface? Is the engine oil filled to the correct level? Next question - how many miles on the engine? Is the engine oil and filter new or recently changed?

      If all these conditions are OK, then you have several possibilities; clogged engine oil filter, faulty oil pressure switch, faulty / worn engine oil pump, worn engine bearing clearances.

    The FUSE indicator light is on and car won't start.
    It's been parked in the garage for 3 months. I run it occasionally, but haven't driven for 6 weeks. It won't turn over and the display shows "FUSE". I also hear a clicking noise after I tried to start it.

    Check engine light on, could it be because of the cold/snow/moisture?
    It came on earlier in the week and i attributed it to the cold weather we were having (it was right after a bad snow storm and i ended up having to drive 2 hours in whiteout weather on the highway) I figured it was because there was some ice build up or something, ...

      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.

    Code 171 system too lean
    cannot figure it out put a new o2 sensor took a few codes off
     
    • Jimm
      2/8/2015 Jimm
      Basically this means that an oxygen sensor in bank 1 has detected a lean condition (too much oxygen in the exhaust). On V6/V8/V10 engines, Bank 1 is the side of the engine that has cylinder #1. The P0171 is one of the more common trouble codes. This code is triggered by the first downstream (front) O2 sensor. The sensor provides a reading of the air:fuel ratio leaving the engine's cylinders, and the vehicles powertrain/engine control module (PCM/ECM) uses that reading and adjusts to keep the engine running at that optimum ratio of 14.7:1. If something is not right and the PCM cannot maintain the 14.7:1 ratio, but rather there is too much air, it triggers this code.

      code P0171 may mean that one or more of the following has happened:
      The MAF (Mass Air Flow) Sensor is dirty or faulty
      Note: The use of "oiled" air filters may cause the MAF to become dirty if the filter is over-oiled.
      There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry. There could be a vacuum leak downstream of the MAF sensor Possible cracked vacuum or PCV line/connection Faulty or stuck open PCV valve Failed or faulty oxygen sensor (bank 1, sensor 1)
      Sticking/plugged or failed fuel injector
      Low fuel pressure (possible plugged/dirty fuel filter!)
      Exhaust leak between engine and first oxygen sensor

      A lot of times, cleaning the MAF sensor and finding/fixing vacuum leaks fix the problem. If you're on a tight budget, start there, but that may not be the fix for certain. So, possible solutions include: Clean the MAF sensor. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling Inspect all vacuum and PCV hoses, replace/repair as required Inspect all hoses and connections in the air intake system Inspect and/or test the intake manifold gaskets for leakage Check for a dirty fuel filter and proper fuel pressure Ideally you'll want to monitor short and long term fuel trims using an advanced scan tool If you have access, you may want to run a smoke test

    What could have caused the cam adjuster to fail at only 20,000 miles?
    At only 20,000 miles, without any warning, and with no prior problems, the car just stopped in the middle of an interstate. After a month of diagnosis, dealer reports that the cam adjuster "failed" and it ruined the engine. Any ideas why this happened?
