Hi All - had some correct advice on this board last time I had an issue - so I thought I would ask again...after searching of course!
I have a rough idleing 2003 Lincoln Aviator that set the 306 and 316 codes for cyl 6 misfire and misfire at startup. I changed coil packs (even swaped them around) and same codes, no change in idle. pulled plug - looked good but swaped it with another cyl anyway - same codes.
Any ideas? I changed fuel filter 6 months ago and truck has 78k miles on it. All plugs were changed about 25k miles ago. seems to be isolated to #6 cyl? Maybe fuel injector? Not looking forward to swaping them - is there a good cleaner?
Thanks for any and all help!!
