    Why is my AC turning hot at stop lights or when the car is in park?
    I drive a 2002 Subaru Forester. When you first turn on the car and turn the AC on, everything works properly. The AC works properly when it the car continues driving (like on a highway for example), but when the car is sitting in park or at a stop light for a longer ...

      Apply a direct 12 volts to the fan connectors to see if the fans are working.
      In the case the fans runs, check their relays.

    Why did my engines temperature spike all of a sudden?
    Have not driven my car for about a month, but turned it on 1 week ago. Now I take it out, get on the freeway and did not notice the temperature till I got off at an exit. Thermostat is good and fans are working. No leaks, hiss or smoke.

      Loss of coolant because of a coolant leak is probably the most common cause of engine overheating. Possible leak points include hoses, the radiator, heater core, water pump, thermostat housing, head gasket, freeze plugs, automatic transmission oil cooler, cylinder head(s) and block.

      Make a careful visual inspection of the entire cooling system, and then PRESSURE TEST the cooling system and radiator cap. A pressure test will reveal internal leaks such as seepage past the head gasket as well as cracks in the head or block. A good system should hold 12 to 15 psi for 15 minutes or more with no loss in pressure. If it leaks pressure, there is an internal coolant leak (most likely a bad head gasket but possibly also a cracked cylinder or engine block).

      It is important to pressure test the radiator cap, too, because a weak cap (or one with too low a pressure rating).

      Perform a cooling system / radiator pressure test when the engine is cold - as a first step to locate the leak.
      Obtain a loaner tool / free radiator pressure tester from the local auto parts stores such as Autozone, O'Reilly, NAPA, Advance Auto, or PepBoys. Follow their instructions and pump it to an adequate air pressure 12 -15 psi or the pressure rating listed on the radiator or reservoir cap. Observe the leaks and perform the repair.
      Note: do not over pressurize beyond the pressure allowed by the radiator cap, then test the radiator cap as well.

    Why do my engine light, stability control light, and cruise control lights still come on?
    The car was recalled to replace the front catalytic converter and re-program the ECM. Since then, the rear catalytic converter, ignition coil, and spark plug wires have been replaced and the throttle body has been cleaned. However, the engine light, stability ...

    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.
