Update: Car does not die going in reverse or drive anymore adjusting the Iac solved that, car also had good size oil leak seeming to come off the back of the engine looked like it was coming from the Rms, so replaced Rms and didn't fix it. Then did entire intake gaskets and valve cover gaskets and problem solved no more leaks. Car will idle okay it idles at about 800 rpms. Issue im having now is when driving and you come to a stop the rpms will bounce up then go back down to where it was and the car will basicly hop forward a little if that makes sense. And this only began after putting everything back togather after doing gaskets, the engine harness is in shitty shape and had **** unplugged and broken connecters(from previous owner) not sure what as far as i know the knock sensor was one of them. Im assuming we must have connected a disconnected sensor and thats the source of the problem. Any ideas? New to v8 and maf input would be appreciated:
