    Engine stalls at idle when my blower motor is on.
    My 04 Baja turbo engine stalls when my blower motor is on for AC or heater. This happens when I slow for a stop or when I idle at a stop. If I turn blower off prior to slowing down/stopping, the engine does not stall.

      Try cleaning the throttle body, disconnect the battery terminals, relearn the idle speed. Also clean the mass air flow sensor. The electrical load that is placed on the alternator from the blower causes the idle to drop which means the idle is probably already too low even before it stalls.

    EJ22 just replaced head gaskets, timing belt and clutch. Starts right up and runs for ten minutes then dies. What's up?
    Dashboard idiot lights stay dimly lit after key has been removed. Must disconnect battery to clear. Engine sounds a little more 'clicky' then before repair but runs good when running. Electrical connections all seem good. Can not run long enough to figure anything ...

      Plug in a code reader and see what fault code is stored. This step cannot be skipped. As far as the head gasket on backwards, maybe. No way to know unless you pull it apart but if there is no overheating then whether the gasket is on backwards makes no difference for the purposes of figuring out the stall. So I assume that after it stalls it does not restart for ? minutes? And I assume that there is no ignition spark?

      Possible bad thermostat. Yes a new one can be bad. Possible air bubble in cooling system.

      Did you bleed the cooling system? There may be air pockets.

    Started with a CEL and a PC004 code.
    Replaced plugs and wires. Ran great for three days. Same code pops up and starts running rough again. Low idle produces a flashing CEL and running horrible. Told could be the fuel injector, preparing to replace on the bad cylinder. Any other possibilities? Don't ...

      Please confirm the correct fault code. No such thing as a PC004 or even a P0004 on Subaru. I cannot assist without the correct fault code.

    Engine misfire at idle.
    Only 2 cylinders firing at idle. Runs good at higher driving speeds 50-80 MPH.

      Check your spark plugs, or your ignition coils.

      I don't think there is an immobolizer. I think plug and play.

    My cars idle speeds up to almost full throttle after I start driving. Carburetor just rebuilt and cant figure it out.
    When started it idles fine, usually I can rev it a couple times then the idle speed skyrockets. Have adjusted fuel and air mixture and idle speed and no change. If I turn the car off and back off it goes back to an idle. Thank you for any input.

      The fast idle may be a combination of: choke adjustment, there is a 1.07 mm gap specification at the throttle plate (slight opening) when the fast idle cam is engaged, when the throttle plate is 16 degrees from full closed, and when the engine is supposed to be at the fast idle speed - typically when the engine first started and cold.

      Here are the fast idle speed adjustment steps;

      1)With the carburetor removed from the engine, set the fast idle cam adjusting lever on the fourth highest step of the fast idle cam.

      2) Check to be sure that the choke valve is fully closed.

      3) Measure the clearance between the lower edge of the primary throttle valve and its bore. The clearance should be the value specified in the Fast Idle chart in this section.

      4) If the clearance is incorrect, turn the fast idle adjusting screw to bring it within specifications. Turning the screw in increases the throttle clearance and vice-versa.

      Yes, plug in a code reader and see what fault codes are currentky stored in memory. You can obtain a code reader from amazon.com for about $20 with shipping and reading the codes takes a minute with no experience. It can only be diagnosed after knowing the codes. This step cannot be skipped.

      You will have either a bad o2 sensor, or Mass air flow sensor. I would also check all lines around the air box for leaks. If you have any more questions feel free to ask.

    Should I fix it or sell it?
    My mechanic tells me this car was in an accident before I bought it (not on the Car Fax) and had a piece of the frame replaced. The engine problems I am having will require a new engine at some point. What should I do: 1) Put in a new engine and then sell it? 2) ...

      Depends on several factors; cost of the repairs, overall value and condition of the vehicle. Given these pieces of information you will be able to make the best decision.

      What are the issues that require a new or rebuilt / replacement engine?

    What is the whining sound that accompanies this car? Is it the turbo unit or could it be something else?
    Car was fairly recently purchased, mileage about 101500.
     
    • Jimm
      3/4/2014 Jimm
      Yes - it could be the turbocharger or something else. Need more information - when does the noise occur? On start-up, on acceleration - at certain speeds? Have you at least raised the hood to observe any noise / conditions firsthand?
      Difficult to diagnose with any accuracy given the description and lack of details.
