2000 Pontiac Grand Am SE 4 cylinder...recent new engine. Roughly 2500 miles. Temperature just above 200 degrees at all times...does not seem normal...when stopped at a light...car idle will jump a few hundred notches above and below 600 and then stall....what could be causing this problem? Gas mileage on full tank only getting 275 or so miles before empty...this also does not seem normal for a 4 cylinder. Can u please help me out?

2000 Pontiac Grand Am SE 2 with a 2.4 liter motor. Has 192,000 miles with the original motor and transmission. I have been the only owner of this cac and have had these issues for over 2 years. The Car will not Idel properly when at stops and will sometimes die. Cylender 3 is missfiring, and the motor vibrates a lot. I have had the computer changed out as well as the computer moduel, ignition coils for both sides, the ignition coil case, the spark plugs, boots, Fuel injector 3, EGR Value, Fuel Regulator, Map flow Sensor, an idel Sensor, and the 0 two sensor. I have taken my car to 2 mechanics and can not figure it out. This recient one did something wrong because now the Check engine, servicec engine, ABS, and track off lights are all on when only the Check engine was the only light on.


P.S. Please let me know how much the donation needs to be.

Thanks Joe
