As stated above, I was driving (a little aggressive) when suddenly the car revved up to max rpms, I shifted to neutral almost immediately and it continued to do so for about 2-3 seconds, a total of no more than 5-6 and I turned it off. Ever since then it has not started, I am completely unsure of what this could be. I’ve heard IAC could cause the issue of revving up, but would it also stop the car from starting now? It’s a terminator swapped motor into a 2001 cobra. Any help is appreciated, just want to get her back on the road.
