Ok Not entirely sure how to use this website properly but I need help, I have a 2011 f 150 5.0 XTR whatever. it has 407xxx km in the ol girl and anyway im dealing with a limp mode throttle body stuck shut on me in Tims drive through tried cleaning it kept sticking it was in the actuator replaced that got it "relearnt" but now it will start and idle and drive for no more than 10 mins then limp mode wrench pops up kills all throttle activity and runs terribly I have a cylinder 8 misfire and cylinder 1 sometimes. It used to do the exact same thing cruising, make a pass and after you pass it would misfire like a bitch eventually clearing up but now you do the same thing if u can get it to run long enough and i have the code P2112 and other times P2111 Any help would be appreciated. compression test was done failed terribly 1-6 had 30-40 PSI number 7 had 5 PSI and 8 had nothing. Just need it to run log enough to get another month out if it until the motor comes Thanks fellas.

 

With those compression numbers, I don't think it will make it much longer.

 

Those compression numbers look to me like you have a valve timing issue. Maybe others will chime in regarding valve timing of a 2011 5.0L.
