I own a 2001 ford f150 lariat 1/2 ton pickup truck with 95,000 original miles on it. On my way to work I noticed it began running very erratic and the service engine light came on, I immediately took it to the shop. The diagnostic check revealed the #7 coil wire was in need of replacement. The shop advised me to change all coil wires and spark plugs as I was nearing the 100,000 mile mark, the cost was $1,200. I opted to just have the spark plugs changed and the # 7 coil wire replaced for $240. The next day the shop called and said there was a big problem, the #7 spark plug broke off during the extraction. The $240.00 cost is now $1800.00. The shop said the head would need to be removed to replace the broken spark plug. I have no choice but to have the work done as the shop told me there was a big problem with spark plugs shearing off during removal because of poor design, they commented the spark plugs have a 100,000 mile guarantee to work, however, the engineers didn't figure on how bad the plugs might deteriorate making removal turn into a financial fiasco.

On two occasions, my 2001 ford f150 (5.4 engine, auto, 4wd) has had the throttle accelerator "stick" during acceleration. The first occasion occurred in february 2010, and the second occurred may 28, 2010 at approximately 10:45 am cst. On both occasions, I was accelerating from a stop at an intersection. On the first occasion, multiple attempts were made to pump the brakes and also the accelerator, when these actions did not respond to the problem, I shifted into neutral and turned of the ignition, and pulled over onto the shoulder of the road. On the second occasion, the same attempt was made, pumping the brake and accelerator pedal; after several seconds and many depressions of the brake and accelerator, I made one final, very fast depression of the brake, which resulted in a noticeable "clunk" sound and accompanying jarring sensation, similar to something disengaging. After this, the truck returned to normal operating conditions. No "check engine" indication was noted before or after either of these occasions of "stuck" accelerator. Fortunately, on both occasions, traffic was very light. If traffic had been heavier, a collision would have been likely to occur.

While on a trip and 400 miles from home , the vehicle started missing severely. We were able to get to our destination some 180 miles further. The following morning the check engine light came on and the vehicle was malfunctioning badly. We got a dealer to repair it. The intake manifold was cracked and causing water/antifreeze to create the problem. The manifold was replaced along with other necessary parts. Apparently this is a common problem on the f-150.

While driving my 2001 f150 truck, the check engine light came on. I took my truck to the garage that does my auto work. They told me it was the egr pressure sensor. They replaced the sensor at a cost of $190.00. Later I found out that ford had issued a service bulletin to have the sensor replaced and they sent letters to the owners to bring their trucks in to have the sensor replaced. Since I am the second owner of the truck I did not receive the letter and since I had 119,852 miles on the truck ford would not fix it." ford knew of the defect, why should I have to pay to have a defective sensor replaced".
