O2 sensors can cause this and often they clear up after a good run.

SOURCE: throttle/Idle/running problem - wants to run too fast, or stall out

RPM's up and down check EGR valve and sensor. EGR valve and sensor control idle. That's why your getting the surging on rpm's and this could be giving out the other codes. If mass flow was bad car will not start and the same for the map sensor. O2 sensor measures gas and air for right mixer. TPS controls 0-60 speed as in throttle respons.

SOURCE: 2001 pontiac grandprix shuts off after getting to

Sounds like the same old intake manifold gasket leak to me. (If it is equipped with a 3.1L engine) Check your engine oil to see if it looks like a chocolate milkshake. For the 3.1L or the 3.8L engine, make sure the coolant level is full. Check the level in the RADIATOR, not just the coolant recovery reservoir. (take the radiator cap off only when the engine is cold)

Why did the reduced engine power and service traction light come on. The car can be started then looses power and stalls out.


When the check engine light comes on it disables other module features as a safety issue. The reduced engine power light is normally caused by a defective throttle actuator motor assembly. In some instances, it can also be caused by a defective gas pedal sensor as well. In my experience, the throttle actuator motor is the most common repair

Traction light on , reduce engine power lights on 07 ss impala what does that sound like .


I know this is not a solution but I too started having this same problem today. Start car, runs normal then all the sudden it feels funny, traction control light blinks on and dash displays service traction control-reduced engine power. This causes my car to sputter like it is going to stall I have to pull over and turn my car off and back on to drive off (only for it to do it within the next 10 minutes). I thought turning TC off would work for now just to drive it, no not successful stil does it : ( I TOOK IT TO AUTO ZONE AND HAD IT SCANNED HAD A CODE FOR GROSS EVAC LEAK AND SOMETHING ABOUT THE THROTTLE PLATE/BODY NOT SURE IF THAT IS RELATED BUT THAT ALL THE INFO I HAVE ON THAT.

2004 grand prix no go with traction control light on.


I had the same problem with my car. I cleaned the throttle body and when i installed everything back, the car would throw 2 OBD codes: P0120 at start up and P0507 when it stalled at a red light. Took it to the dealership and they had to install a new throttle body because the throttle position sensor is internal. Cost = $718.00 out the door. Part is about $480 and labor is 1.8 hours at $99.00/hr (bunch of ****). There is only a 12 month/12,000 mile warranty for work from the dealer so I would recommend doing the work yourself if possible. There is only 2 bolts on top, 2 nuts on bottom, 1 electrical connection, and 1 hose clamp.

My 2000 Lincoln town car is jerking and my check traction light is coming on my car will stall out but i can start it back up


If you have a switch for the traction control, the stalling of the engine can be reduced or eliminated by turning off the traction control.

The traction control probably has debris inside the rear emergency brakes. The traction control works by counting the speed of each wheel. When the part that counts the speed is blocked with debris, it thinks one wheel is slipping and kills the engine and applies the rear brake to the fastest spinning side.

The motor is suppose to lose rpm until the wheelspin is stopped. Then the motor is suppose to run normally. If the motor is completely dying you have a terrible problem with the sensor on the rear wheels.

The Traction control needs to be looked at, some Brake shops may be able to fix it. A dealer would have the tools. There should be nothing wrong with the engine, its suppose to react to the sensors.
