Hi everyone. Hopefully someone can help! I have a 2006 Impala LS 3.5 flex fuel car. My car keeps throwing a code for the APP sensor and puts the car in "limp mode" Takes my power away, the car can't get out of its own way.. I've had the codes pulled and it says that The APP sensor and computer are not agreeing on the throttle position. Also it displays on the cluster that engine power is reduced. I've replaced the APP sensor, had the throttle body cleaned, and the computer reset and re-programed. No difference, I am still having the same problem still. It idle's and revs up with no problems, but while driving it puts the car in limp mode. I'm out of ideas... Please someone help!
