I have a 01 F150 V8 5.4. The other day I was driving down the road and it started riding really ruff! So bad that I thought I might have a flat tire. In any case there was no flat tire the truck still rides ruff and idles bad. It almost sounds like it wants to choke out then it will idel up and repeat the pattern. Today I changed the air filter, PCV Valve, and Fuel filter but the problem only seems to get worse. The only mods I have is an afetr market throttle body spacer, an Airaid intake system, dual exhaust, and I have a hyper tech programmer. After I changed the fuel filter, the check engine light came on. I tuned it back to stock and reset the computer thinking that might help things out. The check engine light went off but the problem is still there. I have run out of ideas. Does anyone have any suggestions? I live in Flowery Branch - anyone know of a good mechanic?
Hey John, if it was a vacuum line & it affected him going down the road, you should be able to hear it in May'retta.
Yeah it was a thought, my '93 Exploder has this problem some times, a vac line pops loose from the intake manifold and the thing feels like it's going to shake itself apart. I have learned with the PSD that you start looking at the "so obvious that couldn't be it" stuff first.
You need to find someone with a OBDII $600 scanner and watch the data. Being a 2001, I would just take it to a dealer. You really do not want someone mickey mousing around with your 5.4. Look for a Blue Oval certified dealer.

I don't know where you are from Morrow, but I would suggest a guy named Courtney at Spartan Lincoln Mercury. He is the best around - modified or stock. Just to tell you how much I think of him - I am having my engine replaced in my Explorer with a new crate engine from Ford - same size - 302 - just a little more horsepower. Any Ford dealership in Salt Lake should be able to swap it out, but I don't trust just anyone. I sent my Explorer back 2100 miles to Courtney to get him to do the work....
Coach, try Bob Menzies @ Car Care America. I have used him and trust him. E-mail me for contact info. or look in "the book". He's in Suwannee, on Peachtree Industrial just north of the Kroger @ 317. Hope this helps.
