Reduced Engine Power | Service Traction Control

chevymom2

I have a '08 Impala LT. I keep getting Reduced Engine Power | Service Traction Control. I have had the throttle body, accelerator pedal, fuel injectors, & PCM|ECM replaced, but continue receiving the Reduced Engine Power | Service Traction Control. The Os2 Sensor was replaced about a year after I bought the car. I am at a loss as what to do next.

HELP !!

I am having the same problem for 2008 Impala LT. Let me know if anyone found any solution this problem.

Get the car scanned and see what codes come up. If you're lucky, it might be a problem with the throttle positioning sensor or throttle body itself---but there are multiple causes for this problem.

I have a 2008 Chevy impala and my car says it has low engine power. It doesn' stay on it goes on and off randomly. The traction control and check engine light also comes on with it. My mechanic thought it may have something to do with my spark plugs and the wires which really needed to be changed..... But now the messaage has come back. Has anyone been able to find a mechanic who was able to figure the problem out? I have to drive over and hour every week day and there is no pattern at all for this problem, it just shows up randomly and it happened the first time on the highway and it' scary when it happens on the highway. My car will slow down and when it eventually builds speed (which is maybe 60 -70) it still struggles. And what's even worse is trying to drive up a hill or bridge, it feels like my car won't make it, like it' driving through water.

If you can't get any help from mechanics you've tried you could consult the list of "repair shops" on this website for especially well-trained technicians. There might be someone in your area, and these people generally will have the expertise to fix this problem:
