What causes misfires?

RE: What causes misfires?
injector could be totaly clogged, that would cause a misfire...which is when a cylinder doesnt complete its job. So a totally blocked off injector could be minimizing the fuel goin into it and not getting enough gas to combust fully. Find a VAGcom or take it to a dealer, it will tell you if it is a misfire and which cylinder (if u dont kno it is a misfire for sure)
EDIT: i worked on a f150 at my shop with a misfire in cyl 5. could be all of the things sandman said plus injectors. Like we replaced the wire on it, still missfired, then replaced the injector and it worked. plugwire, plug, or injector is ur best bet.
