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!

Do you know what codes you have? Maybe take it to an auto parts place and have them pull codes.
It sounds like you might have a vacuum leak.

Sounds to me like a battery or alternator issue.
