Changed plugs about a week or so ago erveything cool, yesterday started running rough SES light comes on, scanned and PO316 comes up something to do with the gas vapor. Little blinking symbol c and ev.
I probably knocked something off when changing the plugs.

Any advise would be appreciated.

 

I remember you. Yea, good luck with that. Couldn't happen to nicer guy.

 

Don't know why your acting like that with me I never said anything to offend you that I know of. If I did I apologize if it's not to late. I did get off track on a couple issues and people, Don't we all from time to time even you j??

 

Yea, well they are friends.

Did you use Motorcraft plugs? PO316, - Bad coil or bad connection on the B+ wire at the coil.

You should have another code besides just the 316. The other code directs you to the cylinder #.

 

I sent PMs to people I offended apoligizing to them.
Yes I used the exact OEM plugs from the dealer all numbers the same with gap.

Thanks for the tip will check it out.

 

Could be a bad connection , - coil balde to coil spring. If you used anti-sieze, it could have dribbled down and fouled the plug on a 4 thread head.

 

Misfire on #6 defective COP.

Thanks Again Sultini
