Hello Im new to this and was wondering if anybody could help me. I have a 2004 Ford F150 FX4 5.4 3V. The last few weeks the truck has been missing and starts shaking real bad. When I had it hooked to the scanner it showed intake manifold runner control stuck closed bank 1. It dosen't do it all the time and it does not show any kind of miss firing code or anything like that. I have taken it to two garages and one of them didn't have any idea what the do and the other thinks that I need to take the intake off and try to clean the butterfly openings. Has anybody else had this problem and if you did what did you do to fix it? Thanks
