    We're on our third go around at mechanic. ABS light comes on after idling and then gears don't engage or jerk into gear.
    So far replaced ignition, worked on electrical. Drove fine coming home from mechanic. Idled for a few minutes, ABS light on and same problem with operation. The car has 108,000 miles

    Why do I keep losing so much coolant in refill tank?
    I have to keep refilling the coolant tank numerous times. Otherwise, I'll get a warning light that my coolant is low. When I check, I'll see that the tank is almost out of coolant, so I'll have to add more to fill it back up to the appropriate level. This happens ...

      Loss of coolant because of a coolant leak is probably the most common cause of an engine . 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 while the engine is COLD 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.

      The most common cause of overheating is because of an external leak from a water pump or a radiator or heater hose. The way to find the leak is to wait till it is overnight cold and maybe just pour water in and see if the leak is large enough to see it simply leak out from where it has a leak. if you pour in a half gallon or more and you still see no leak its time to pressure check the system.

      Here is a short list of possible causes for overheating;

      Low coolant level
      Leaking coolant
      Improper coolant concentration (not at recommended 50 / 50 mix of anti-freeze and water)
      Clogged radiator hoses
      Clogged heater hoses
      Clogged radiator passages
      Clogged heater core
      Faulty thermostat
      Faulty water pump
      Faulty radiator cooling fans
      Faulty radiator cooling fan switch (coolant temperature sensor)
      Faulty / worn serpentine drive belt
      Faulty / worn drive belt tensioner

      Thank you lots!! Any idea why the car would be smoking white smoke from the muffler??

      Yes, the most likely cause for the smoke is a faulty cylinder head gasket. Have a cylinder leakdown and compression test performed to determine.

    My engine RPMs go straight to and stay at 3700 when I start the car up. Any suggestions?
    I checked the throttle while starting the car. The throttle doesn't open up at all when it revs up, which doesn't make sense. Even though the throttle doesn't move, the engine still revs up. This all happened right after I took apart the throttle body and cleaned ...

      Believe there maybe an issue with your mass air flow sensor or throttle position sensor. Try unplugging one at a time And see if rpms spike or if it runs smoother.

    My car will randomly go into a rough or missing idle, from a perfectly normal idle.
    This has happened five times in the last two months. Turning the car off, then immediately back on, causes it to idle normally and return to full power. It will then stay normal for weeks, until the next incident. When it happens, it is after the car has run for ...

    URGENT: My car is stuck at full throttle when i start it up, after cleaning out the throttle body. How do I fix this?
    I took the throttle body apart, cleaned out the sensors, and put it back together. Everything was working fine before I took it apart.
