    96 Ford Bronco 351, I am on my 3rd EGR valve in three months. I have reset the code several times to verify code but it comes back on about a week after I put in new EGR. Code is EGR flow insufficient. P0401 it is the only code that comes up.

    From the message I posted above, I am on my 3rd EGR valve in 3 months. Could the catalytic converter cause the EGR code ?

    gator,

    did you ever get the problem solved and what was it? I may be having the same problem with my 95.
  • dgiustidgiusti Posts: 3
    driver321,
    I have a 95 with a 351 that has true duals, sounds goods and runs good but just remember that the mufflers (especially flowmasters) will be right under the back seats and you will definately get some internal noise.
    Be careful with Flowmasters, stay away from the 40 series.

    I have a 95 full size with a 351. It runs perfect for about 20-25 minutes then starts to run rough almost like a miss. I've changed plugs, wires, cap, rotor, o2 sensor, ignition module, fuel filter. Check engine light is not on. Prior to this starting I ran Lucas fuel injector cleaner through it and now am hearing bad things about that stuff in older vehicles. Has anyone experienced anything like this and if so what did you do??????

  • dameen6dameen6 Posts: 4
    how are you PHERNON,well i have a 88 bronco 11, i had similar problems with mine,here's a couple of things you might want to check, driveshaft,universal joints,gears in the rear end, I don't know if you have automatic locking hubs check em also,check yur radius arm on both sides check the insulator and washer they usually are wore out and is rubbing on the crossmember that is some of the things that were done to mine. I HOPE IT HELPS YOU, good luck and let me know if any of them were bad, hopefully it isn't yur tranny, thats were i am stuck for now.

    I have a '92 V8 5.0L Ford Bronco and I have a problem with the engine in the morning. The fuel pump needs to run for about 15 minutes before it has built up enough pressure to start.
    The mechanics think it might be either the connection on the fuel pump. They're going to connect all three tubes seperately instead of together with one clasp.
    If that doesn't help all they can do is replace the on board computer. My faith in mechanics is a little gone since I've spent more on repairs than on the initial amount I paid for the car.

    Has anyone had the same problem or does anyone have any suggestions on where the problem might really lie?

    :confuse: Any help is appreciated.

    Thank you! Danielle

    I had this problem before and all it was is a sensor in the engine. It only cost 85 dollars to replace. After that you won't get that jerking anymore. I thought it was the trans but it was only a sensor.

    I have an 87 bronco that quit me today, it started twice but died each time after about 2 minutes or so, I'm thinking fuel filter but not real familiar with the fuel system yet, please help, my other truck is a diesel and diesel fuel prices are going through the roof, I have to get my "ol bronc" back on the road
  • I have a '93 full size Bronco 351 motor Dana(?) drive train w/140k problem started with a "thump" when shifting into reverse, hard ("jerky") shifting, then a vibration/"shudder"(like I'm riding over small rumble strips) when accelerating at 40-55mph. First time to shop they reccomended a service (fluid,filters,etc.) and a product called "shudderstop" for the torque converter. The "thump" went away and it was better for about a month then the shudder started again. Second trip to shop they tried a "shift-pak"(?) and solenoid(s). The thump and hard shifting are gone but I still have a vibration/"shudder" between 40 and 55mph when I accelerate. Any suggestions before I research replacing??? I hope to keep my Bronco indefinitely so I'm not opposed to replacement, but if it's not necessary I'de like to keep my money.
    Thanks

    I would recommend checking your drive shaft as well as your tranz. You may need new universal joints. If at 40-55 mph you start to fell like it wont go any faster then i recommend doing as i suggested, if it stops as you accelerate past this operating speed i would recommend having the front end checked. good luck!

    Will a 1986 ford Bronco rear door fit a 1992 bronco? My stepson's bronco got hit by a school bus and the only door he can find is a 1986. If the 1986 will not work what years will fit.
    Thanks

    thanks for the reply!
    i have checked the drive shaft and there does not appear to be any "slop." the "vibration" has now migrated to other points on the speedo and happens when accelerating. if i turn the "overdrive" off it happens less frequently but continues.
    i am also considering replacing the front shock towers. it looks scary though. any tips?
  • droplever1droplever1 Posts: 5
    I have had some success by "googling" "ford replacement parts"
    if you don't find the exact door, you may still get an idea of what you can use instead. i'm not sure if i am supposed to do this or not, but i have used jeffs bronco graveyard.

    My air conditioner works great while under idle but under acceleration it changes direction and blows warm from the dash I know it is a vacuum problem and I have allready changed the canister. Just wondering if anyone had any Ideas?

    im not sure if it will help but i have a 1981 bronco with the windsor 302 (but out of a mustang) and i had the same problem of it stoping on me (left me right in the crap) like yours there was no spark... the tow truck driver said it was the amp for the dizzy... as i was going to mexico i left it untill then to buy a new one and while i was there i did so... when i got home to england i fitted it but to no avail... a friend of mine said stop messin about finding fault and just replace the whole dizzy with a HDI unit... i did this for £120 and it works perfect, all it needs is one live wire and one for the taco, and it is a performance part too... im very happy with it... go to geffs bronco graveyard they have them on the shelf for like $105..

    hope it helps

    hello

    i also have an 81 bronco and i had the problem of there being no radio at all and none of the wires being there to rig one up easy... so first of all i found a ford double din cd player to go in it... and i got the plugs for it from a scrap yard (i think you call them piggy backs there) and i was lucky enough to have mate who was able to rewire a new harness for the radio... aparently it was easy according to him... but i am sure you could find a spurious wireing diagram on the net or in an old chilton manual or haynes manual... it may be more simple and reliable than using the harness

    good look from england...

    I have a 96 ford bronco, 5.8 automatic, runs and starts good, but when I turn on the headlights the engine dies, would seem to be a short, but does anyone know if it could be another known problem ?
  • tidestertidester Posts: 10,109
    One thought that comes to mind is that it may be your alternator. It may not be producing enough electricity to power your engine with the headlights on. Anyone else have any ideas?
