2008 Chevy Impala LS check engine, abs, service traction, and reduced engine power while driving but speed wasn't affected. Maintained 60 mph with no surging or fluctuating rpms....car drives fine

 

Codes??

 

I had the same with my 2009 Impala. It would come and go. It was caused by the throttle position sensor, bad solder joint in there.. Requires replacement of the accelerator pedal.

 

I replaced the accelerator pedal today . So far that code is gone but still seeing one for camshaft position sensor and it was changed a month or so ago. ABS and service traction lites still on. Pretty sure it's the wheel speed sensor on passenger front. Checking it tomorrow thanks for responding

 

Did you clear the codes after installing the pedal?

 

Did you ever resolve this?
