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!

Welcome to the forum. For starters, https://www.way.com/blog/how-to-fix-a-p0507-code/

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.
