Id Change your plugs gaps have opened too wide . Set to .28 thousands

No biggie but 28 thousands would be .02

Doubt it’s the tune since it’s doing it with the oem reflash. Going to change plugs as suggested and see what happens. Thanks all.

I get what your saying but maybe something in the tune contributed to an issue that is now also seen after flashing back to OEM.

You stated "it was tuned by goosetuned and ran fine until this weekend." , however, you didn't state how long you ran the tune without issue.

I bought the truck tuned but have owned it for the last 10k miles without issue.

I should add I talked to the tuner and he also recommended plugs.

I have this spark plug socket set works good. Be carefull installing if reg 5/8 socket is used people have side loaded plug when installing/tightening and cracked the porcelain causing misfires.

bring it someplace other than a dealer.

dealers suck. and that sounds like a fairly isolated issue.

sounds to me like whatever the tuner did got jacked up.

Sweet . Yep I used to change mine on my the tremor at 10000. If I waited I would get misfire around 12000. What did the gaps open up too on the plugs u pulled out?

This morning I was at my local dealer for oil change. My only day off and a lot to do today. In and out super quick. Talked to a 81yr old man in waiting room. He has a 16 3.5 eco f150 and they gave him a recommended services. They told him his plugs were due and coolant change. Recommended is 60000 for plugs. He said I thought they last forever to service writer. He said he will have it all done next time around. Service writer is good guy not pushy. Old man tells me he just turned 127000 miles on truck , original plugs. He does all highway and set cruise and go ,no towing . I was impressed told him you must never step on gas hard . He laughed and said once in a while.

Not sure. I was so happy to have her running strong again, I didn’t check. Thanks again.
