My buddy has a built c5 z06 has a 383 stroker procharger new fuel system 80lb injectors. He was driving the car perfectly 1300 miles well pulling into our town he hit a path where they tore the pavement up and bottom his car out. The car threw a reduced power/traction control code. He got the car home found out his 02 sensor wire was cut. Replaced that and the car when started will not idle it will idle around 500rpm then when given gas it will rev up but pop and backfire. He has no codes and we replaced the plugs. Hes getting perfect fuel around 60 on his gauge. What could be causing this issue?

Sounds like he took a lick... I'd check the MAF connections and make sure there isn't a leak sucking air .....

Only codes are low voltage cause he's speed density

It's what came from the dic. Here's the thing he hit the pump car shut off found out wire to pump came loose reconnected that drive it another hour that's when it died the second time. So first pump wire came lose them found later o2 sensor wire was cut
