today i was driving home from work and my freind in his formula was behind me and i decided to show off by slamming the gas to the floor and leave him in the dusst, then it kinda died then backfired and was running agian! and a few days eairly i was driving and i hit a pretty bad pothole and the car just shut off. i was able to start it up very easily . thinking i had a bad ground i checked my wires and cleand up the contact areas but that must not be it! cause it still dies on huge bumps. also about a month ago i replaced a crank sensor because of a code 43 after that it drove good and didnt get a code..... not sure if this has anything to do with whats going on now though.

 

did you check to see if your computer contacts are clean/ connected all the way? this is a common problem....

 

i just checked pretty much all connections and they look good and i just put dialelectric grease in all my connections maybe this may help? ill have to lay on the gas tomorrow morning before work and see what happens. ill throw it on the diagnostic computer at work too and see if i can find any problems.
