I I have a problem with my 01. I can start it sounds awesome press on the gas and it moves but sounds like it's running on 4 cylinders. Any guesses?

What engine do you have first and how many miles on the truck?

4.6 it's a buddy of mine truck so not sure the mileage. But he has gone through the entire fuel system and changed the spark plugs.

If I changed the basic ignition parts, the fuel filter and was sure I was getting fuel, which might include getting access to the intake and spraying some wd-40, which is some volatile fuel and then I checked the timing, I'd be at the mechanics....then again I don't know much about sensors, but I do know that computers in vehicles tend to throw codes. I also know my mechanic is very fair, very honest and when I have suggested unnecessary stuff, he has said "don't waste your money."
