Hi I'm new to the Ford world I'm mostly a dodge guy bit I have just acquired my late grandpa's old truck and it's a 94 f150 with a 5.0l and it's having some issues. When it's cold it runs good but misses a little, but after it worms up it runs like crap and when your driving it just looses all power and you have to feather the gas peddle to maintain any kind of speed but it's not much acts like it's looses all power. I got it from my aunt and uncle and they had it at 3 shops and they couldn't figure it out. Has good fuel pressure, has had a new cap and rotor and looks to be new plugs and wires I have a code reader and will include the codes I got from it. I was able to get it to run a little better by turning the distributor and adjusting the timing a little but still not running right. I've sorta narrowed it down to the cat is plugged and the vacuum advance ( has good vacuum) is not operating correctly. And I know the fuel pump codes is likely a ground for the fuel pump as when I picked it up and got it on the trailer both tanks were working but now I only have one tank. Thank you in advance
