Have an '07 XLT 4x4 144,000 on it, recently had hvac line explode over cyclinders 1-4 causing cyclinder 3 misfire. Dealership replaced line, and "cleaned" and re-installed plugs 1-4 after that when I accelerate hard I have hard hesitation through about 55 mph BUT when I take off normally no hesitation runs smoothe. I replaced my coils 1-4 with some BWD's no joy. Thinking my plugs might be bad, any install the Champion 7989 plugs yet? Any ideas to help? Thanks

Eric

Welcome to the family Bosco...IMO...stick with the Motorcraft replacement.

Thanks for the warm and fuzzy, by the way I replaced my top of the line motor craft spark plugs with champions dual platinum 7989 plugs and bwd ignition coils. I feel the difference alread, I've driven about 50 miles on them so far the engine is very responsive is purring just fine.

I have a 2nd Gen, BUT, if I were to guess, I'd say some of the Freon/oil may have been sucked into the intake via the normal air inlet.. It may have gummed up the MAF sensor. Might try cleaning it first.

True just like a dealers is if they think they are going to give me anything over $13k for my 08 Expy that has 78k miles which i think is bs because they would try to sell my Expy for around 24k.

let me guess, it's black? Almost certain it was used in a livery service capacity... although, if in fact, a limo there is alot to be said for that, you know all of the maintenance has been done... altho probably worn out back seats, lol

Nope it was white with the unpainted lower plastic and was located here in Salt Lake City Utah.

Ok update its been about 640 miles since I replaced the plugs and coils, everything is still peachy. I'm at 145246, feels like it did when I bought it with 5k.
