3.5 EcoBoost HELP!
Hi this is my first post on this forum, just looking for some help with what’s going on with my truck. I own a 2011 F150 EcoBoost with 108,000 miles on it. The problems started on a rainy day in California where there truck lost power and the engine and wrench light came on. I took it to our mechanic where they started with the plugs... didn’t help. Next we did all the cool packs... nothing still misfiring. Finally I took it to ford where they told me I need injectors...$2500 later I get my truck back and it’s not missfiring but only making 7-8 lbs of boost. Once I saw this I opened up the engine bay and took of the cover to discover a plug completely disconnected. I hooked that back up and got to around 8.7 lbs of boost max? I am at a loss any input helps. Btw truck was on sct 91 tune but that was removed once these problems persisted

Throttle Body is a pretty cheap part and have failed causing odd issues.

Since the Ford dealership screwed up and left you running on 7 cylinders maybe take it back there and let them finish what they started. Good luck.
