Hey guys, I'm new to the forum. Hopefully I can get some much needed help. These past 3 weeks I have been having issues with my GT. It first started as I was driving down a highway and the RPMs started majorly surging. It started out going from about 2k-4k then gradually went down as I pulled over. I checked everything out and it seemed to return back to normal idle. The days after that, it began to surge while idling and progressively became worse. I took apart and cleaned the throttle body and MAF thinking that would help, but no luck. After that we let it idle and it still surged while idling. I gave it some gas and it threw up the wrench and completely died. I tried replacing the TPS and that seemed to help with the surging while idling. But it still dies and the wrench light comes up when I give it gas. It is also giving me the codes P2111 and P2104. Any insight on this would be much appreciated. I am at my wits end and miss driving my baby very much. Thanks in advance.
