I was driving my 2022 c5 corvette and a couple of times it would just turn off for no apparent reason then i was pulling up my drive way and it all of a sudden started running really rough like something had come unplugged. I cleaned the MAF put on a new tps and took off the throttle body and cleaned it now it starts for about 5 seconds then runs rough and stalls. The codes are p1120 po336 p1220 p1514 p1516 any help would be appreciated i would like to get it running before it snows thanks in advance
