hello I have a 2005 Ford F 150 5.4 3 valve I have a problem I have replaced the cam phasers fuel filter catalytic converters all spark plugs all coils cleaned mass air flow sensor clean throttle body and a few injectors the problem I am having is the truck has no power sometimes it does sometimes it dont whenever I'll run it hard from a thousand RPM's to 4500 rpm in first gear it does fine when it runs its next cycle from a thousand RPM's to 4500 rpm in the next gear it throws an alarm code 306 cylinder number 6 misfire and it runs really rough for about a minute while the check engine light flashes and then it goes away and smooths out what do I do next

 

What do you do next ???? You should learn some penmanship in order for that mess you wrote to be understood.

 

Penmanship ? Someone should take his ink away.

 

Thanks guys for all the help damn yuppys can't help anyone

Is #6 one of the injectors you replaced?

Sorry you had to get a blast from the forum police, but when you don't title the post with anything but the word "help" and write a post in one long sentence with no caps or punctuation, that is going to get you a blast in just about any forum out there. Your post is very difficult to read and make sense out of. Obviously you are not an English major, but please make a better effort than that.

 

My feeling is, if they can't even write..... I know he knows how.

 

Yes I have a masters in English lol j/k. I have removed the cats and replaced injectors #6 is one I replaced. The truck has no power it won't get out of its on way

 

No codes other than the P0306? What did you use for spark plugs, coils, injectors, and cats?
