Im gonna check all my sensors a little later today, i have a spare 02 sensor i gonna try that as well. its just weird that it onlys does when i floor it and the problem stays after that even daily driving untill i restart the car.... making me think it is a sensor being reset just dont know which one. There is no check engine lights on either. i would take it back to the shop but its about and hour and a half away. Anybody else got any suggestions?
