Ford Super Duty (1999-2016) :: 2002 F350 TPS - Low Crawling / Throttle Is Very Jerky Off Road
May 10, 2016
My truck is a 2002 F350 CC dually longbox 4x4 7.3 auto that I bought last fall. On the street it is very well behaved although I suspect it is not giving me as much power as it should be, as compared to my previous 95 powerstroke.
Off road, slow crawling, the throttle is very jerky. Under acceleration it is smooth, but if I try holding a low throttle position, the rpm rises and falls. I am certain this is a bad TPS, and may also be contributing to my perceived low power on the street.
I have googled my brains out and it seems there is a cheap replacement TPS for earlier trucks but the 2002 has the 5 wire combined TPS and IVS, which reportedly is not replaceable without replacing the whole pedal assembly. To complicate matters I have the adjustable pedal assembly
So are there any options other than buying a complete pedal assembly from ford? Can I save some bux and retrofit a non-adjustable pedal assembly? I saw a youtube video where a guy put a newer 6.0 pedal assembly in but he was short on specifics about what exactly he gained doing this.

After the hard downshifting full throttle highway run low speed stomp on it freeway cruising tires spinning on gravel crawling through town day yesterday -
my tranny just doesn't know what to do!! One thing that it does like to do is make that 6.2 spin and sing! Eventually we'll be on the same page so we can work and play seamlessly.

2000 F350. 4x4, V10. 153,xxx miles. Here's the story. Whenever I hit a little bump in the road, I get a vibration directly under my feet and in the gas pedal, NOT in the steering. It will go away pretty quick or when I hit another bump. It only happens when the front driveshaft is not spinning. Hubs locked in in 2WD, it doesn't vibrate. Hubs unlocked and in 4x4 High it doesn't vibrate.

I am installing a set on a '12 F350 for a customer. I already had to go buy an additional hardware in order to get the back bumper on correctly...and now I'm looking at the front bumper and I swear I don't have the parts I need to install it. It appears to be missing some brackets. There were NO instructions with them (apparently a chronic problem with Road Armor) and I can't possibly imagine it bolting to the flimsy brackets that hold the factory bumper (fairing would be a better word for it) in place.

I have a 1997 f-350 crew cab 4x4 w/ off road package and 7.5 fuel muncher power package. My engine stalls going down the road w/ no warning. Sometimes it will start back up immediately, and other times not until i cycle the ignition 6 times or so.it seems to be getting worse as time goes by. Since it started i replaced tps, cap, rotor, plugs and wires. I also replaced fuel tank and pump and filter about 1.5 years ago. Some other issues to clear up, but concerned w/ current problem.

I have a 2005 king ranch and have a clunk coming from the back over bumps/heaves in the road. It doesn't happen all the time but often enough. I just replaced the shocks, that worked a little but didn't solve the problem. Now thinking rear sway bar end links? Anything I can check/inspect?

I have a 2005 F350 diesel, 54000 miles. I was at a red light today, engine is idling normaly.. light turns green and I step on the throttle and get nothing. My truck is rolling (in drive) as if it were in nuetral. I shut the engine off and it does not start for 10 to 15 min. Then it fires up and seems to be running as if nothing happened.

Have a 06 f350 just rebuilt the engine. Started up ran it down the road a couple miles and lost low side oil pressure. Got back to the house and will not start again so put a gauge on and it only has 3 lbs after cranking for 10-15 sec. Pulled the balancer and lpop cover and front cover had some deeper scoring then before. No noticeable stuff in the pan or filter. Changed out the front cover and lpop. Still has only about 5 psi.

It's an 02 f250 4x4 crew with 7.3, 6 in lift and 35 in tires. It has all ways wandered a little bit and I just accepted it. I changed everything in the steering from ball joints, tie rods and drag links less than 2000 miles ago. Everything still seems good and tight. Recently it has gotten a lot worse so I checked again and everything seems to be tight. Where to or what to check next? It's to the point I don't feel safe letting my wife drive it and I don't enjoy driving it.

About 6 months ago my 4 wheel drive stoped working and I wasn't worried about it because I never used it. I did mess around with it allitle bit to try and fix it the one time I did need it. Long story short I was involved in the floods near Houston these past few days but my truck was never in more than a a foot of water. I went up the store and grabbed a few drinks and went home. tuesday when I went to get in my truck to head back to college station for school it was stuck in 4x4 low. whick puzzled me because my 4 wheel drive hasn't worked in a good while.
When I turn the key on there is no 4x4 lights that come on momentarily and when I turn the 4x4 switch still no lighst come on. Again its been this way for 6 months. I tested the two relays under the hood and both of them have power. there is no power going to the switch in my dash and no power going to the solenoid on the transfer case. Wich is why I am confused on how it went into 4x4 low. I assuming it is in 4x4 low because of how fast the tranny shifts and I know its locked because I cant turn my front drive shaft while in neutral. The hubs are unlocked. I just printed out a shematic and am gonna try to figure out why my 4x4 isn't working.. to hopefully fix it so I can get my truck out of 4x4.

I recently bought a 2002 F350 and so far, the only issue I've had with it is I can't find out why the ABS light is on. I've looked around and found that it's probably caused by the speed sensors. But this is where I run into issues. From what I've seen, a bad sensor will generally give a reading of 0 ohms, but none of mine do. The rear diff sensor gives me ~1800 ohms, which I believe is OK.
The front driver side reads about 700 which is I know is a little lower than it should be, and then my passenger side reads ~42 mega ohms. Both the front sensors kind of threw me off since what I've read says they should all read about 1200-2500 ohms. Any other things I should check or should I just go ahead and replace both front sensors? I've just looked around and have barely been able to find anything about the front sensors.

Just completed the rebuild on the front end of my 02 f350 and of course I had to take the abs sensors out, everything is good but now my abs light is on. Is there a method I can use or do i have to hook it up to scanner and erase the code.

My truck seems to shudder between 40 and 60 mph when it's in OD. If I turn off OD it seems to go away with the increased rpm's. Although I can't be sure if it genuinely disappears or if I just don't notice since I'm at 2100 rpms instead of 1500. Trans fluid is clean. Is this a common problem in these trucks? Just filled up from flat E the same day air temps about 4 deg. Truck was fully warmed up. Does this sound ignition related, tranny or fuel related?

I have a 02 F350 V10 4x4. Tonight I went out to go to a friends house and the truck started fine but when I push in the brake it will not release the lock on the shifter. You can hear a click noise when you push in the brake pedal.

The batteries keep dying. I can charge the batteries and drive it to work a couple of days and by the fourth day, it's dead again. Have replaced alternator, batteries, and starter and I am still having issues. Just noticed this weekend, the instrument cluster going off, coming back on, shutting off again all while the truck had been running for about an hour. I'm not sure if it is because the battery was dying or what. As soon as we got home after the instrument cluster incident, turned the truck off and tried to start it. The battery was completely dead.
I have been looking up on sites and I keep coming across the GEM Module. I want to ask around before I buy it. I have also noticed small issues with my 2000 Excursion. Back windshield wiper starts up upon the vehicle starting. Goes a few times and stops. Not sure if this is the same type of issue as in the GEM Module.

2002 F350 Super Duty 7.3 Diesel.Transmission trouble. Came off interstate - took foot off throttle at yield and hit gas as turn was clear. Did it fast and felt like hit wall. Immediately lost transmission engagement. Trans did not reengage until below 20 MPH. Tried to speed up and disengaged at 20 to 25MPH - just free wheel - engine wine. Went to 1st gear and would come up normally. Shift to 2nd and could get up to 30MPH and probably higher - didn't push. Shift to drive and trans disengage. No trans fluid leakage and level looks good and clean. What to look for? 126K miles.

I have a 2002 F350 V10 and one night I turned the headlights on and when the ignition switch was turned to the off position the lights would go off. When the ignition switch is turned off the lights come back on. I changed the ignition switch but the problem still exists.
