The vehicle may be over fueling or not getting enough fuel at idle . Could be caused by a sensor in the engine reading improperly, spark plugs with excessive gap or a vacum leak. Chances are this vehicle has a check engine light on that would give you a better indication of what sysem is being affected causing the problem.

SOURCE: 1994 LT1 Engine "balks" under acceleration intermittently

Your fuel pump or your catalytic is plugged. have it tested with a infrared gun it will tell you if the cat is bad and if it is replace it test the fuel pump for fuel rail pressure it should read 50 psi then hold to 20 psi for 1 minute.. Also check to see if the intake plate is dirty and if it is do a top engine clean, buy GM's top engine cleaner and run it threw the engine, if you have carbon buildup the compression and cause the car to run bad and the knock sensor will not be able to adjust time. I know this sounds silly but these three things will cause your problem and so will a bad fuel filter.

SOURCE: car is bucking, engine light on code po742

"Torque converter clutch" solenoid is stuck open which is causing your bucking problems. The solenoid is either disconnected or faulty. if you ran over something, it may have damaged the wiring, but if not, you need to take it in for checkup.

SOURCE: 2000 Impala ls car runs fine when first start.

There are NO choke coils on your vehicle, so don't bother looking for something that doesn't exist, just like there is NO carb on your engine. What you have is either a 3.4 or 3.8 liter V-6, sequential multi-port fuel injected engine.

The first thing you should do is replace the fuel filter. This is located underneath your vehicle, in front of the rear suspension. You will need a 10mm socket or wrench to remove the bolt that holds on the mounting bracket for the fuel filter. You will then need to push the fuel line forward towards the filter, while you are pushing in the white plastic retaining clips, then while holding them him, continue to hold the filter with one hand, while pulling back the line with the other, It should easily come off. Repeat for the other line. I recommend this as the first step, because many vehicle owners don't bother to get their fuel filter changed as often as they should. It should be changed at least every 24,000 miles.

Drive the vehicle and see if that took care of the problem. If not, you most likely have a bad fuel pump, which is mounted in the fuel tank, a bad fuel pressure regulator, which is mounted on the fuel rail on the engine, it is usually black with a vacuum line going to the top of it, and you may also have a catalytic converter that is starting to go bad, as once they heat up is usually when the internal grid expands and can begin blocking the exhaust.

This may all seem overwhelming to you, but an easier solution might be for you to take it so a reputable shop and have them run diagnostics on it, with you then bringing home and doing the repair yourself to save on parts and labor. Diagnostic fees could run slightly less than $100, to slightly more than that, but could save you from buying and replacing parts that you don't need.

Hope this helps.

the coolant could be just overflow,, as far as the temp,, replace the thermostat as a first thing, when your car gets that hot, it causes readings to be sent to the computer that sends mixed signals to other parts of the car, The first thing you should do is pull the diagnostic codes. This will tell you if the thermostat is dead.check the temp sending unit, it is located under the upper radiator hose, 19mm wrench will take it off, it costs about 20 bucks but you also need to replace the thermostat. all in all its about 25 bucks total and all your gauges work fine....

I have had a similar problem.Check all of your Radiator and Heater hoses for leaks. The cooling system doesn't need to lose much coolant to create overheating problems. If you find no leaks -check that your bottom radiator hose isn't sucking flat and restricting coolant flow.
