Ford: DONT KNOW WHATS WRONG WITH MY TRUCK, vacuum leaks, pressure guage

Question
MY TRUCK HAS BEEN RUNNIN LIKE ITS MISS FIREING BUT I CHANGED THE PLUGS TWICE, THE WIRES,CAP ROTOR, AND COIL AND IT STILL RUNS LIKE ITS LOADING UP. ITS A 1993 FORD F150 FUEL INJECTED 302. I ALSO CHECKED THE CONVERTER TO SEE IF THAT WAS PLUGED. THE ONLY OTHER THING I COULD THINK OF IS AN INJECTOR IS FIREING WRONG OR MY COMPUTER IS JUNK!!!!!!!!!!  PLEASE HELP CUZ IM GETTING READY TO SMASH IT INTO A TREE!!!! LOL

Answer
hello


Firstly, compuotrs and injectors are not common failures on fords


ok.. did it just start running badly?
does it miss or stumble at idle? or only under load? when cold? or only when hot?
what are the KOEO, KOER, and continuos codes?

How did you check the cat? with a pressure guage or vacuum guage?

what is timing at?
what is mileage?

Is fuel good? Has the fuel filter been checked/ replaced?

what is engine vacuum at idle?

what is fuel pressure and delivery?

Has it been checked for vacuum leaks?

Any signs of rodents under the hood?
