I have a misfire, when I checked the code it was P1347 misfire #3, I changed plugs, coils and still have the same code, changed the vvc both of them no help I even changed the intake gasket twice, and changed the intake it self with another use one that I know it was good, torqued the nuts at 16lb, still have the same problem, checked the coil wires and were good. HELP

I would suggest pressure testing that cylinder, Also check the wiring and fully inspect the coil connector on the harness for corrosion/contamination.

ckecked pressure on #3 and was about 155, changed the injector and the spark plug, tested the coil and had a good blue fire. was holding pressure at 155, but still have the misfire on #3 and the car feel like it. As I said before I changed intakes and intake gaskets too. can't think of anything else, any idea anyone?????????????????????
