Getting codes P0174 and P0300 on a 2004 F150 FX4. It has had the infamous tick but just started acting up a little bit more. When i go to get on the highway, once i hit about 60mph or 2000rpm, the truck shakes furiously and i cannot accelerate. I can then put it in neutral, rev up the engine and then let rpms drop back down, place back in drive and then carry on like there was no issue. Another catch is that it only does this when it is cold. I have recently just replaced all spark plugs, just changed the oil, and cleaned out the MAF. Whats next?!
