Was just driving and it overheated, replaced water pump, sensors, wires, heater coil, themorstat twice, all to no avail, took it to 2 mechanics and they couldnt figure out what was wrong with it. Cleaned out the raditor with a complete flush and run fine for about 2 months, we also put 2 new computers into it.

Purchased vehicle, heating did not work - air would blow out cold. Dealer blew out heat core and replaced thermostat. Minimal amount of heat. Engine started to stutter and stall. Fuel injector in 5th cylinder bad. Mechanic flushed injected and gave tune up. Ran ok for a week and then constant stutter and shake at 50 MPH. Mechanic replaced 1 injector. Stutter gone. No overheating, but antifreeze leak x 1. Replaced water pump. 1 week later constant overheating and puddle of antifreeze around engine block. Then the engine stalled and I checked the oil to find the dipstick showed twice the amount of oil after sitting for 8 hours. Just had oil changed 1 week after repairs, I had the oil changed, that is when the oil appeared overfull and the car stauled.
