F-150 5.4L Triton

  • Automatic transmission
  • 107,500 miles


It started when my wife drove the truck about 60 miles round trip. She called me and said that the truck was chugging and shaking and died at the stop lights. I drive this truck 98% of the time and had not experienced these symptoms. My trip is short both ways under 12 miles. About 4 days later it started on the short trips and would come and go. It got worse and the Engine light came on. I took it to my garage they ran the codes and didn't want to touch this engine?? I started going on line and I now know why. So I changed my VCT's and cam sensors fairly easy job if you are mechanically inclined. The codes reset and I took the truck for a ride. It was not responsive and about 8 miles later started killing at stops. The shaking and chugging weren't there though. I figured plugs next at 108K so my garage agreed to do it, hesitantly. Once they got it they checked and no codes and no misses. He pulled the belt and let me know my timing chain and/or tensioners are bad. He didn't do the plugs and basically told me to either spend the 3k to fix it or get rid of it. Again he would not do this job and suggested that if I keep it take it to a Ford dealer and get the warranty. I've read enough to agree with him. Ford knows this is an issue and it does go back to the constant loud pinging I reported earlier. Why are they not offering the customers at least a parts and low labor rate to do these repairs that are inherent to the Triton motor? I have always stayed with the proper oil, filter etc. I may have waited to 4k once in a while. This is a TRUCK and shouldn't be doing this at 100K or less in a lot of instances. I am maybe was a Ford man all my life and I am disgusted with this. Anyone looking on line can see the issues and should stay away from the Ford line. I also had an issue similar to this back in '09 on the road and it cost me a fortune. Don't have details at this time but will post this issue in the near future along with the drivers window motor replacement.

F-150 FX 5.4L

  • Automatic transmission
  • 106,000 miles

Could not answer some of the questions , because the truck is still in the shop. I think they have replaced everything but the Radio.... They fix the Miss,,,, then it starts over, it has been the shop for a Month.... No telling what they are doing.... They say the fix what the computer says , drive it , it runs for a couple miles then starts missing again on another cylinder..or two or four... They say this ford engine is a factory screw up.

I am stuck! Any Hints? dale

Update from Feb 13, 2012: Well it in now 2/13/12. Truck still in the shop, so far new plugs,cam censors,battery,coils,new oil,timing change etc., not sure what else, sent to the Ford Dealer, they know what to do .... back to the other shop, Looks like we are back on the rack. I saw something on the Blogs , about the Timing Ring in the Differential What the hell would that have to do with the engine missing? HELP...dk

F-150 5.4L V8

  • Automatic transmission
  • 114,000 miles


I bought my 2004 f150 crewcab truck with high expectations, after all ford is the number 1 selling truck in America. I had no problems with it untill 3 days before going on my annual hunting trip from Kansas to Wyoming. The truck would run fine untill it came to an idle, at which point it sounded more like a diesel. I took it to several shops and heard everything from "we need to change the engine" to "have you tried different oil?" I finally had enough and had to bite the bullet. $1700 later the mechanic had changed both cam phasers, both tensioners, both guides and both timing chains. Oh and not to mention the high dollar spark plug from hell that broke off.

Need less to say I was and am not impressed with Fords new motors. I did test drive a Toyota Tundra while my truck was down and I will tell you this.....NICE. My next truck will be a Toyota. Check them out I think you will agree.

F-150 FX-4 5.4L V8

  • Automatic transmission
  • 43,000 miles

I can't believe at 43,000 miles I had to have major engine work done because of a problem that I didn't cause or could prevent. I asked the dealership what caused this and they said, "poor design, they changed it after 2005 and it will be fixed with the new design." Ford Tough, this thing has been babied unlike my Chevy 3/4 ton work truck with over 136,000mi and just a water pump replacement!

F-150 5.4L

  • Automatic transmission
  • 100,000 miles

It started at around 100,000 miles. Hadnt really caused any problems but it was an obvious problem. We didnt mess with it for a while but when it came time for a tune up we had it fixed. We were told not to worry about it until it triggered a check engine light. I dont believe it ever did but we had it fixed anyways.

F-150 Lariat 5.4L

  • Automatic transmission
  • 108,000 miles


Son had a 2004 F150 lariat 5.4 engine, auto trans, with 108.000 miles on it, changed the oil every 3000 miles with ford motor oil and motor craft filter. It started getting engine code misfire. Local mechanic said he thought it was maybe the coils or plugs. We took it to a Ford dealership, they thought it was something internally in the engine so we took it to a Ford dealership I trusted. They said it was If I remember correctly the left bank cam was bad. They had worked on 2 other 2004 F150 just like my sons, one a week before and I think another about 3 weeks before that. They said to really fix it they suggested a new engine. My brother inlaw working for an oil company as a pumper drove a 2004 5.4 and the same thing happened, and the engine was replaced. A friend of my sons 2004 5.4 engine had to have a new engine due to the same problem, the cam.

F-150 5.4L

  • Automatic transmission
  • 20,473 miles

I had just had truck in shop for tapping noise and they replaced coil assy and spark plugs at 20,387. The engine was still running rough, so I had to replace gaskets, spark plugs, valve rocker arm, reset engine timing, reinstalled valve covers and timing cover, recharged AC system. Next I will do more work on the spark plugs and gaskets to see if that fixes it.
