I reset the code and drove about 2 miles and it has not come on. I am going to clean the MAF sensor and see if that keeps it away. Is there anything i can monitor on my accessport to make sure my car is running safe? I am keeping it under 3k rpms
Sounds like something popped or broke when you were doing the pull.
Check your couplers
