My '99 F-150 has 124,000 on it and still gets 16 mpg back and forth to work. Ive see older E-Series vans with Triton engines with over 300,000 on them with no problems (one of them was a work van that had almost 500,000 on the original engine).
The days of vehicles being worn-out at 100,000 miles are long gone. If my brother's '92 F-150 can last 220,000 miles (and still going), my F-150 should be able to last 200,000 miles NO PROBLEM!

My 97 f150 has 117,00 miles. The motor & tranny are in great shape. I'm having the usual problems associated with a old truckl. Its vacuum lines had dry rotted & many sensers have gone out. Other than this its been a ok truck. My old company van has over 250,000 miles now & its motor & tranny are its strong points. The vans body & front end are shot but the 5.4 runs great. Its still going around 500 miles a week with no problems

I'm picking up a new F150 this week (hopefully, waiting on the bank to finish a home refi) and one of the reasons why is the continued reliablity I've seen out of the 5.4. Granted a lot of it has to do with proper maintenance, but that's not a big sacrifice to make considering the benefits, safety, and peace of mind you get from driving a well maintained vehicle.
I had a 94 4 cyl ranger, got 220k out of it. A lot of that was city mileage. All I replaced on it was the fuel filter, TP sensor, tires, and 1 set of plugs and wires.
My Grandpa's 78 Ford pickup got 336k before the odometer stopped working. He replaced 1 alternator on it. Before it just absolutely quit running, about 3 yrs ago, it never leaked a drop of oil or tranny fluid. I'm not too worried about any of Ford's products.

What does the IAC look like. I know it is an Idler Air Contrller. Someone gave me a description and there is like two or three parts on the engine that looks like it. On a 2000 F150 5.4, if I think it is what it is, it's on the right hand side of the butter fly valve manifold.
