Ok I have a 2002 F150 V6 that has been a real pain as of late. It all started when the truck would miss a little bit when it rains or got washed. Then the truck started missing almost anytime I used it. Now the truck wont start and when it does will not accelerate and misses BADLY. I replaced the coil and now it starts again and run better but its still skipping. I replaced the wires about a year ago. Iv had a check engine light for 1.5 years for o2 sensors.

Any ideas whats going on....

 

There are 4 main problems that can cause a misfire.
bad sparkplug
bad COP (Coil on plug) - the wire that sends the spark
bad fuel injector
piston compression problems.

I'd bet on a plug or injector...

 

yea cause without spark and fuel you aint goin nowhere....id replace the cop's cause mine sputtered and one was bad...if not atleast pull em and check the boots cause mine was melted and it cause'd a prob also so boots are a simple fix

 

The 4.2 don't have cops^^^

 

well i just changed the plugs and its still doing it. So that rules out plugs and coil. Maybe ill get new wires too just to be sure. Also anyway I can check the injectors?
