HELP! 2011 malibu 2.4 IDLE SPEED HIGH,ENGINE POWER REDUCED, LOW TRAC, SERVICE ESC, P1400,P0507
My 2011 Malibu all the sudden started idling high, I assume it then switched to limp mode as the dummy lights came on. It was shuddering violently a stop. Long story short I cleaned the throttle body, Which didn't help so I replaced the throttle body and the spark plugs clean the map sensor and the intake I'm at a loss....... Can someone help please thank you in advance!
