      Which parts? Likely very few - maybe from the engine or transmission.

      No there are virtually no parts that are compatible from a Corolla to a Camry. Maybe the oil cap and radiator cap.

    Why does my car's heat work intermittently and while its not working it wants to overheat the engine?
    I had a coolant leak for a bit when I first bought the car, early in 2014. I ended up going through the engine and checking all the hose fittings in an attempt to find the leak. I didn't find anything major so I ran one of those no leak radiator treatments through ...

      It seems that you are describing what happens when the cooling system is low. No place in your details have you stated that you confirmed that the cooling system is not at this moment as these symptoms are happening - low on coolant.

      The ECM (engine control module) will need to be reflashed / set up elctronically for your particular vehicle - whenever the ECM is replaced with another unit.

      even if the two 4runners match up as far as motor and model?
    • Jimm
      3/7/2014 Jimm
      Yes, that is correct - any ECM change would necessitate a reflashing / reprogramming due to the vehicle parameters being unique to the individual vehicle.

    Ecm for a 4runner change over
    will a ecm out of a 2004 toyota 4runner 4x4 4.7 match up with a 2005 toyota 4runner 4x4 4.7 without having to flash it?

    What could be the problem with stucked accelerator pedal, not all the time.
    Car runs fine, and accelarates with no problems, sometimes when stops, accelerator pedal gets hard and in order to move, has to be pushed really hard down to the floor.

      i put a holley throttle body on a pickup once and if you let off the pedal fast the throttle would go too far and get stuck in the throttle body. try pushing the pedal down then slipping your foot off to the side and let it snap up frome there unhook your throttle cable and see where its stiff. throttle and breaks are a big deal though if you have had to stomp on the pedal a couple times i would look at replacing the cable just to be safe.

    Check engine light came on

      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, etc. 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 fault codes and therefore numerous reasons for the MIL condition.

      This step is important - retrieving the stored fault code and relaying this detail - will provide good information to assist in diagnosing and repairing the issue you are having.

    What would cause my truck to die when put in gear
    changed the plugs and wire
     
    • John's Auto Repair
      Does this happen when the engine is cold as well as warmed up? You may have carbon
      buildup on the throttle plate as well as the throttle bore. I would have the throttle body
      cleaned

    The heater in my truck doesnt work blow warm air unless i am on the highway or excellerating
    There is antifreeze in the radiator and overflow tank

      If you are certain that the radiator is full and has been bleed, then you may have a partially
      restricted heater core.

    AutoMD Member - 2006 Toyota Highlander - Engine - 2/28/2014
    Heater only blows cold air out unless i am excellerating or on the highway.
    The radiator antifreeze is full and so is the overflow tank.

      Plug in a code reader and see what fault codes are stored. You can obtain a code reader from amazon for about $20. Update the post with the code numbers. Checking for codes cannot be skipped.

    Why does my car hesitate when I put on the gas kind of skipping but engine rives?
    Occurs when driving more at lower speeds. I notice it from gas petal and the skip it makes.

      Possible Causes of Engine Hesitation or Stumble:

      Dirty fuel injectors (cleaning the injectors often fixes this)
      Dirty air filter (change filter)
      Dirty / clogged fuel filter (change filter)
      Bad MAP (manifold absolute pressure) sensor
      Bad TPS (throttle position) sensor
      Bad or dirty MAF (mass airflow) sensor
      Low fuel pressure (leaky fuel pressure regulator or weak fuel pump)
      Vacuum leaks (intake manifold, vacuum hoses, throttle body, EGR valve)
      Bad gasoline (fuel contaminated with water or too much alcohol)

      Sometimes, what feels like a hesitation is actually ignition misfire rather than lean misfire. The causes of ignition misfire may include:

      Dirty or worn spark plugs
      Bad plug wires
      Weak ignition coil
      Wet plug wires

      Are you comparing this with how the car used to run? Is the check engine light illuminated? Can you buy a code reader from amazon.com for $20 and plug it in and read fault codes that might be presently stored in memory?

      you can buy a idiag and iobd2 for read car code, it‘s cheap
