Truck started jerkin etc @ 35 40 mph, check engine light came on and I pulled the code: po358 ignition coil h. So I replaced coil and plug, no change, still have bad miss. Pulled new plug again and it looked like it was real wet, thought maybe injector might be stuck open or somthing so I replaced injector. Still no change . Any ideas as to what else it might be ? Any help would be appreciated.
