I got into a front crash with it airbags deployed and everything replaced the radiator and throttlebody now when i start it it starts off at 5,000rpms does that for about 3-5 seconds then jumps down then starts back firing do I have a bad computer or something else?

 

Vacuum leak, IAC?...

 

Check the bellows tube between the throttle body and the intake manifold. Bet that's the issue.

 

Thanks it was actually my whole intake manifold most of the bolts were broken after i got into the front end crash it pushed it I guess and broke then so its all good now thanks
