Why is my 1997 GMC Sierra 5.7 vortec missing in cylinder 8?
My 1997 GMC Sierra with the 5.7 vortec has a
cylinder 8 misfire after I replaced the spider injector.
I checked the plugs and wires and they seemed to
be okay. The truck needs timing can that cause a
misfire if it’s a little out of time? I also changed the
distributer,cap and rotor not to long ago.
