Hi, I have a 1992 Ford F150 with the 5.8 in it. I bought it from original owner a few years back, I have now put on 25k miles. Just within the last month once truck is warmed up (as of lately it's higher on the gauge then normal, but is still reading normal range) I can get up to about 55mph and then it starts to shake and buck when I accelerate. I have read a few forums that had some suggestions, clean out throttle body and replace gasket (did that last night, did not fix problem) this afternoon I will be replacing fuel filter. I also read that could be just the plugs and wires, I will check those after new fuel filter is installed. I am starting to run out of ideas, I am about to turn 21 and am struggling with what I want to do in my life, so I have decided to enlist to become an mechanic in the Air Force. I just need this truck bad to running smoothly this thing is my baby and I want it to be running smooth before I leave so once I get out I can completely restore this truck to keep it forever. I have only 130k on it, before these problems started I had no problems whatsoever.

Along with the shaking and bucking I have a couple other things that started once that started too, when I slow down to about 5mph and come to a complete stop it sounds like something is slammed and/or grinding. I believe it's somewhere in the front end.

Also there's a sound coming from passenger side front wheel area, like a card in a spoke, it was on the drivers side front tire for a while but now it went away and switched sides to passenger side.

If anyone can help with any of the problems that would be greatly appreciated.

Thanks, Blake.
