the car is going in to limp mode and misfiring under light throttle and normal driving. some times shutting off. it keeps throwing codes and putting me in to limp mode. i clear the codes and it goes away. but comes back. got the car to drive so i can post a log. if i restart the car the codes come back and the only way to make it idle ok is to clear the codes while engine is on. also for some reason it wont let me flash xhp, i believe it was slipping a little too hard to tell with everything that was going on
