Could Computer Have Been Resetting?The old 85' f150 is running great now. I didn't do a thing with it except drive it a bit and let it sit for about a week. I drove it this morning to work, about 35 minutes of side street and freeway mix and there was no sputtering, or mumbling or odd...

ThanksThanks for all of the good advise, I'll try some things out this weekend. Any other things you can think of will be of great benefit.Phil

Help, my 85' f150 5.0 efi runs great when it's cold and warming up. Once engine is warm it will buck and kick and sputter until I let off the gas or hit the gas. At idle the engine speed goes up and down and up and down and if left alone will vary so much the engine will die. Fuel filter...

I am Phil. I own a 1985 ford f150 5.0 efi. I love my truck but occasionally need help with it. I hope I can count on you guys to lead me in the right direction when I get stuck on a problem.
