Ford F-Series Computer Problems

    My truck is an older F350, I had the same problem, but started out intermittently, then one day nothing. Mine turned out to be the camshaft sensor. Check into that.

    My 95 F350 started shuttering and acting like it was starving for fuel. I have 3 tanks on it and switched between all 3 and no luck. I checked all the fuel supply lines, all were tight, I put a vacuum gauge on the pump and it was pulling 25 inches. I changed out the year old fuel filter (which looked like it had some wax on it) so I figure maybe I got some wax in one of the injectors. I have been running diesel kleen and lucas through the fuel constantly, before and after the problem, but it still acts the same. If there is a better cleaner, please let me know, or is there something else I should check?

    Sounds like a clogged exhaust pipe. Disconnect the exhaust pipe as close to the engine as possible, reset the codes and crank it up and see what happens, do not run it for too long this way.

    Check and make sure the flexplate didn't break (if it is an automatic). It should have an access plate down by the transmission you can look in and see if anything broke or the teeth are worn (or pull the starter back out and look in).
  • Hi i have a speedometer that starts of bouncing around and gets worse the faster i go. i replaced the speed sensor on back pumpkin and had the truck hooked up to a computer. i had the speedometer/odometer tested . all is good any ideas, i thought maybe computer?
  • My F250 diesel smokes black smoke when I press relatively hard on the accelerator after it warms up. When it is cold, it does not smoke and runs just fine. I realized that my air filter needed cleaning so I did that and it helped a bit. I then used MAF cleaner and cleaned the MAF. It did not make any difference. Do you think the MAF might be bad? If so, how can I tell.

    FYI, last year I had the head gasket and head replaced as has many people had to. It has 137,000 miles on it.

    2003 7.3 ltr. the radio,dome and windows stop working. There is no apparent "outside" factors such terrain or precipitation that instigates this fault. sometimes power returns with in a few minutes, sometimes an hour. any suggestions.

    check your GEM module, do a search, somewhere I have the info regarding a small leak that gets the back of this unit wet, causing all kinds of weird electrical problems.. on fords, escorts, lincoln navigators, etc..if I find it, will post the info.. ah.. right after typing this, went to the previous page, and wa-la.. there it is.. all about the GEM module.. ;)
  • I know that it has been a while since this was posted, but I am going through the same problem with my 94 f150. It has a 4.9 with an A4OD and has approx 135000 miles. I am into my third PCM. The shop just says, yep there must be something else wrong, but offers no suggestions. How did you fix yours. Any ideas anyone?
  • Was there any underlying faults to the vehicle prior to any of the PCM's going out, stalling, not starting, anything like that? you weren't unplugging it and plugging it back in, with the ignition on, were you?
  • By the way, how long did the PCM's last?
  • Anyone had this issue? My check engine light came on, so I took it to the dealership. They hooked it up and the code picked up indicated that someone installed a performance chip or tried to modify the programming. I've NEVER hooked up any chip or tried to modify the PCM in any way. When I told the service advisor this, he basically called me a liar and said I would have to pay for a new PCM at about $1000! Any advice would be greatly appreciated.
  • My 200 F350 with 7.3 is giving me issues. The truck was losing power and wanting to die at any rpm above 2000, so i checked and replaced the fuel filter. ran fine for about 1 month started again figured i had some trash in fuel replaced filter. problem is this time white smoke like it starving for fuel and then it will clear up and can go down road then check engine light will come on and truck starts sputtring and white smoke again and speedo starts jumping up and down about 10 to 15 mph, just dont have any other ideas need help.
  • May need to replace the fuel pump
