Ok here is the deal. I have been working on a lift for a while now. It has the Gm motor and it runs and accelerates great but it has a miss at idle. It had a blown intake gasket which I replaced. Runs better but still misses at idle. I have tuned it up wires and plugs. All cool pack are good. Replaced the mass air flow and cam shaft sensors. Replaced all 4 fuel injectors and it has a new vaporizer on it. I have no other vacuum leaks. It's throwing the camshaft code but it's fine all my voltage check are in specs. Anyone have any clue what to do next?
