Chevy Impala Reduced Engine Power
HELP! I have an 06 Chevy Impala with a little over 100K miles. Routine maintenance always taken care of. As of the past couple months I have been getting the ENGINE POWER REDUCED message on the dash. Power is kicked back, and speed is reduced as well. I have already taken the advice of the other posts and replaced the throttle body first...did well for a while, and then error popped back up. Yesterday I replaced the accelerator position sensor while we had warmer weather...ran fine last night, only to give me the message AGAIN this morning when it began to get colder outside. I am out of ideas. Anybody have any isight?
