Hey guys need some gurus help, been trying to diagnose my car myself to save some dollars..
So my 2004 vz alloytec randomly started to run like crap after driving along the highway, after coming to a stop at home it was idiling pretty rough, I checked the car the next morning and started Fine etc, after driving it for about 10-15 minutes it began to misfire again… I then began my diagnostic side of things by checking coil packs… I came across bank 3 coil pack being faulty and not working… I then replaced it with a new coilpack… car started and drove fine about about another 10-15 minutes and the misfiring came back but was intermittent misfires wasn’t consistent… then eventually it came back as before and became consistent … I then Began to check coils again and some how it was the exact same one… I then changed spark plugs and gapped them to 0.7 as recommended by my mechanic and switched coilpacks over with a different one… then after the misfiring has just become consistent from start up and still from bank 3 the coil unplugged is making no difference… I then began to dig deeper and changed the injector around to see if it switched which coil it would misfire from and still hasn’t made any difference…. I’m lost in what I have to do right now…. Car was running absolute perfect till now… please help
