I have done a 5.3 swap with a hot cam in my 1995 4x4 chevy truck. It has a manual trans and transfer case. I hope that ya'll may be able to help me out. Heres my problem. When you first crank the engine you can rev it for about 2 min after that it just chokes itself out when i try to rev it. IF I hold the throttle in a certain spot it just surges like its getting gas then not. Ok so I take pin 32 and 34 on blue connector and apply a ground and i have my throttle back. I tried to find some info on this and everything I find saying the vss not hooked up. I belive I do since my speedometer is working. Does anyone know what im doing wrong. Thanks for your help and time By the way this is my first time asking a ? I've done all this project by searching on this site but didnt have any luck with this one
