I converted my car back to stock from a vf39 conversion. I put everything back exactly as it should be, checked and re-checked connections, but I am getting a CEL and my car will not rev at all. If I put the gas to the floor it will slowly rev to about 2k and not go any further.
The only thing I can think of is an electrical problem, but I only had to mess with the o2 sensor to convert back.
Also the CEL will not go away with a battery reset, so I am assuming its electrical.
It won't rev at all, so I cannot take it to autozone to get the CEL checked.
