Bucking and snorting on acceleration

Congrats Sasquatch you convinced your first Raptor owner to drill a hole in his intercooler.

...

What's sad is the owner is more inclined to drill a hole in his intercooler than to spend $2 per gas station visit at an attempt to burn through a few tanks of Premium fuel. Even if that ends up not being the issue, at least you've eliminated a factor, one that the dealer is likely to tell you to do anyway.

Not for nothing, but super is almost .50 more per gallon than 87 octane where I’m at, so it’s closer to $5-10 per station visit.

Wow. This is NOT fuel related. This has been proven by the ecoboost owners from way back in 2011. Why not learn from their trial and error???

Betting your plug gaps are too big or cracked plugs , problem on early ecoboosts . Plugs will develop a vertical crack and plug gaps were not consistant from factory.On My 14 ecoboost i keep my plugs changed every 10,000 miles i will develop a WOT misfire at 12,000 miles. I gap them at .28 thousands when i change them after 10,000 miles they are open to 34 or 35 thousands. Too big a gap for 20 psi boost.

You needed the weep hole to solve your problem. As long as you had that, new sp534 plugs gapped .030, and changed out every 30k you would have had a trouble free experience.

He wasn't using 87 he was using mid grade

Same Problem

I have the the same problem. The truck is 2 months old and it's been doing it from day one. I have ran 93 from day one and I have checked the following.

Checked plug gap and they were all at around 28 and no cracks. I took the intercooler cold side tube out and looked in with my camera scope and found no condensation so no weep hole needed . I checked all the clamps on the intake/intercooler to make sure they were tight. I used Forscan to check for missfires and found none. I reset ECU by disconnecting battery overnight and that just fixed the erratic shifting issues I was having.

Next step is the dealer.

Are you running in 2wd?

I run 2wd but have tried it in 4wd in normal and sport mode and it still does it.

You are correct in that you will never see fluid left in the intercooler as the engine is not running. It only builds condensate when it's running and it is passed through (causing your misfires). You need the weep hole because you never know when the fluid is building up.
