throttle body gasket n the intake manifold.. I turn
it on and still missing fire worst than before and i
dont k ow what could it be help
Take throttle body and intake back off and reuse your old metal gaskets. As long as they not bent they will work just fine. I have done it lots of times with no issues. Don't use any type of sealer on them.
The intake in my avatar picture has been on and off at least six times using same gaskets every time.
