Ford Excursion :: ABS Light / Speedometer Intermittent But Only Under Engine Load?
Oct 7, 2013
Just bought an '03 Excursion v10 with ~150,000 miles on it (Saturday morning). About 3/4 of my 1.5 hr drive home, when I hit my first small mountain, and I put my foot into it, the ABS light came on, and the speedo started bouncing around. Same thing on the second hill/mountain.
Then, after driving it on a couple small trips this weekend, and towing my 2500 lb boat home (20 min drive), it behaved fine (no big hills, etc). However, I decided to hookup my backup camera. During the 60 or so minutes that I had it sitting with dome lights on, etc measuring everything up (also trying to figure out how to fit my tool box in the back).
When I tried to start it when I was finished, it would just crank and crank and crank. Every now and then, it would try to catch, but never would. Left it sit for another 10 minutes and it started just fine. However, once it started, the ABS light came on for a little while, then went out.
At first, I thought "oh no... fuel pump". But then I started thinking about the speedo and the ABS light going whacko on the hills. I'm wondering if it's a low voltage issue? I had the alternator checked out today, and it tested fine at 13.9v. However, I've heard that those tests aren't always accurate.

My 2002 v10 4x4 with 103k is parked in my garage overnight so its toasty when i leave the house. But I've noticed when it sits out in the cold all day i'll get a intermittin ABS light. i left work one day at the first stop light i had a flashing ABS light. once the light turned green it went away and the system worked fine.
Last night the truck sat out in 5F weather, i remote started it so it was warm inside.. I left home and noticed about a mile down the road the ABS light came on and the speedo dropped, this lasted about 2 sec then came back no issue after that and the abs system is working just fine.
So, my question is what sensor would it be? I'm not 100% on how it works with the excursion. i know my explorer has a sensor in the rear axle and 2 sensors up front. i have not tryed pulling a code as the light doesn't stay..but i may throw the OBD2 reader in the console so i can try to catch it next time?

Saturday I stuck the ex in a snow drift, rocked it back and forth in low range about six or seven times, once i got it out the engine shudders in overdrive. If i lock out OD it still shudders under load, It starts at around 40 mph, if I push it up to 60 and let off the throttle it stops and is smooth until I start to climb a hill. It never did this before It is a 2001 V10 with 143,000 miles, where to start looking ....

As I'm driving along, I get the battery light coming for a few minutes then going out. Is this a sign my alternator is on the fritz?

MY 04 Excursion limited has 154k miles on it. Up until about 2 weeks ago the RSS worked great. Then the light on the dash that turns the RSS off when you are backing up a trailer was intermittently on/off then it stayed on the whole time. The switch doesn't lock in one position. Like the clicker is bad. I got a new switch hoping this would fix the problem and Momma could back her school bus up with no problems. Not so. I checked out all the sensors and when you get in front of them individually you can hear them clicking. but the switch is still stuck in off. I disconnected the battery and reset the system and it still doesn't work. I cant find any schematics in my Haynes/Chilton manual for this system. there is no fuse for it in the owners manual.

Having this issue for a while. Finally have time off work to dig into it some more. 00 ex, v10. Intermittently flashes o/D light and shifts hard. I replaced 2 out of the three speed sensors. One at the output and the other on the axle. Only active code is the p0720 output shaft speed sensor circuit. Last weekend removed and inspected harness, did not electrically measure it tho. My question is: intermittent problem? I drove it today to see if it was still doing it and it drove like a dream! Haven't had the battery disconnected or anything, just sometimes it does it and other times it a smooth ride.

I have a 1999 Ford Explorer Sport. In the past month, I have experienced on a number of occasions a sudden fluctuation in the speedometer. At the same time, the ABS light will come on and the engine becomes loaded. This will last for a second and then return to normal. The interval between occurrences is not fixed or repeatable but often occurs when traveling at a higher speed (65-70 mph) on the interstate. The first garage said it might be the idle valve so we had it replaced but the problem appeared again a few days later. We just recently took it to a Ford dealership that said it might be the rear wheel ABS sensor so we had this replaced. Once again the problem reappeared a few days later.

My current truck is an early 99 F250, 7.3L diesel, CC 4x4(manual shift transaxle) auto transmission. It is basically stock, with the exception of a hutch/harpoon and a new fuel pump over the winter, an AIS intake. I have a magnaflow exhaust kit in the garage along with bellowed up pipes but have not installed them yet.
Here is my issue. Several times over the last 2 years, the truck will pull a load, or long trip, and with complete randomness, the engine will feel like it has shut off, there is usually a jerk or two, and the truck "restarts" itself and continues on like nothing happened. Last year we drove 1.5 hrs from home with the boat in tow, driving up Snoqualmie pass, and it died completely, no restart. We had to be towed home. It started right up at the shop, so no real clue of what happened.
When this happened, I had the fuel system checked for pressure and replaced the engine fuel filter, and all was good. I also had the Cam position sensor replaced/updated to the new grey sensor. Shortly after, I had the minor jerk/stall occur again, so I replaced the fuel pump and did the hutch/harpoon mod to ensure there wasn't an intermittent fuel pressure loss and that the in tank filters were not clogged.
Last weekend, i pulled my boat to Oregon, and the same "hiccup" happened as I was about 1.5 hrs into my trip. it was fine after that the rest of the 4 hr trip. We also drove back the same route and had no problems.

Well mine was. Checked all vac lines, 4wd was fine, tested with vac pump tested ok. So first I replaced the canister. Nope, actually happened more often. Pulled the 4wd solenoid that's mounted on the inner fender, rusted and split just above where the vac lines connect. I capped them and now my a/c is perfect, 4wd is out but for now I can live without 4wd.

My speedometer is off by around 5mph. When I'm going about 65mph it only reads about 60mph.
How is this corrected? Programming or speedometer cable gear?

I just got my excursion and it skips really bad when going up the bridge, or when it is under any load. I definitely need to change my plugs. I also may need to change my coils. Is it okay to get the cheap $8 coils off ebay or do I need to spend the money on the $75 ford Motorcraft?

I have an 08 Camry that appears to be having the problems associated with the ABS module (intermittent A/C, speedometer not working, etc.).
I've picked up a module/pump from a junkyard. Excuse my ignorance, but the module itself (black portion), does not have any fluid circulating through it? If I'm just swapping that, there is no need to bleed the ABS or perform any programming?

I have a 2007 prius and the speedometer display is intermittent. I would like to know if there is an online manual for replacement or how to even get this one out? I'm going crazy!

So we finally found a travel trailer and picked it up yesterday. It is a 2008 Jayco 29A. Fiberglass with aluminum frame. 5345 dry weight, so shouldn't be too taxing on the Ex, but we towed it through parts of the NC mountains to get home and on steep grades it would downshift to 2nd gear and I would hear what sounded to me like pinging from the engine.
As far as I know the plugs are original, so should I just go ahead and replace them, or there also a possibility that this is just the notorious exhaust manifold leak? If all exhaust manifold bolts are still intact, is there a good test to know if it is the exhaust? No engine codes were thrown. The truck has 72k miles on it now.

2000 Expedition AWD, 4.6l ... 150K on car, 50K on trans, 150k on transfer case and most else.
The problem is, under load, there is a intermittent bearing vibration noise...it sounds like a roller bearing that has too much tolerance so it vibrates in and out under acceleration. You can feel it in the gas pedal and chassis, you can hear it, and it robs a little power when the sound it pronounced. The sound is 10x worst when towing my 6000lb boat. Gear doesn't seem to matter, but it is hard to make it happen in 3rd gear.
Diagnostics so far:
-Can't reproduce sound on rack or out of gear
-Stethoscoped all accessories - good
-added Lucas oil additive to engine oil - no change
-added Duralube high mileage goop to trans - no change/slight change?
-Aamco said it was transfer case, tear down and inspection revealed nothing, they said it was mostly pristine for a car with 150K on it.
-Inspected U-joints - all tight
The duralube in the transmission may have made a slight difference in the frequency of the sound...but it could be my imagination, it wasn't significant enough a change to be determinate.
I think I could isolate the issue with a diagnostic tool that doesn't exist as far as I know...it would be a handheld device with 4 magnetic mic sensors you could stick in various locations and watch the waveform output on the handheld... you would simply move the mic's around until you got the highest amplitude on the readout.
At this point the only thing I can think of:
-Aamco missed something
-Main bearings, cam bearings, or possibly oil pump
-Transmission bearing (Aamco says "NOT")

So I have had my 02' Camry for a little over a year. Love the car, it is a 2.4L SE with a 5-speed manual. Recently it has developed this mystery misfire/hesitation under a load and at idle with the AC on. I replaced the plugs with OEM Toyota Iridium and it seemed to clear it up for about a month, but now has come back. If I start the car and turn on the AC it will intermittently start to miss but not only when the compressor is engaged and it does it every now and then under a load specifically in 4th or 5th gear under a load with lower RPM's (under 2000).
The check engine light is not on and hasn't as much as even flashed on at any time so there must not be any hard misfire codes. I want to stop by Autozone and see if they will scan it to find any stored codes but haven't had time. I would think that if it was a coil pack that it would be a hard misfire. I'm stumped. This car is in great condition...no oil leaks, interior is near perfect (replaced a worn shift knob, and door panel pieces around the window switch). Also car has 160k miles.

I just bought this Excursion, well actually traded my motorcycle for it.
When I test drove it the air bag light was on and there was no radio or 3rd row seat in it. The owner told me that he had removed the 3rd row seat (and seat belts) along with the DVD system with headrest monitors at the request of a buyer that wanted the truck without that stuff. He then told me that the air bag light came on when he removed the DVD system. The truck was also missing the wiper arms.
I explained that I was interested in the truck but ONLY if the above problems were fixed.
The next day he calls me to tell me that everything has been taken care of and we could make the trade whenever I was ready.
So I rode my bike to him. The 3rd row seat had been installed and the wipers were fixed. He had installed a different radio and told me it would have taken him all day to get the DVD back in but he would give me the system and I could install it. I figured ok, I don't mind doing that and I can make sure it is done right. The air bag light was off, so I made the deal.
Driving home I noticed the speedometer was not working and that the truck wandered a lot. I noticed the wander on the test drive but didn't think it was as bad as it now was. About a mile from my house I could smell hot brakes. Before I smelled the brakes I called the guy and told him about the issues and that I would take a quick look in the morning in the daylight. He assured me that he would take care of any problems that I found.
The next day I pulled the gauge cluster to see if there was a loose wire... there wasn't. But I did find that the air bag light wasn't on anymore because the bulb was removed. At this point I was very upset and called him and text his wife and got no answer. Since I couldn't really drive the truck with the dash pulled apart, I put it back together and decided to look at the rear brake where the smell was coming from. Around this time I noticed that the 3rd row seatbelts were not installed. Also that the truck is riding on C load range tires with a bit of dry rot.
I went to pull the rear wheel and the lug nuts were those spline ones where you need a key. Of course the key wasn't in the truck. I was however able to get a 3/4" socket on them to get the lugs loose. I found the brake problem to be a caliper mounting pin was rusted in place not allowing full retraction of the pads from the rotor. I figured this one wasn't his fault as I didn't notice it the day before. So I ordered new caliper mounts and hardware from Rock Auto. It was going to take a couple of days to get the parts so I drove my car to work the work next day.
After work I stopped by his shop. He gave me the key for the wheels and explained to me that he paid a guy $200 to fix the air bag light and that he was going to go over and demand his money back. He also told me that the seat belts were tucked in behind the interior panels and they could be just pulled out and bolted up. I gave the guy the benefit of the doubt and went home.
After my brake parts came in I installed them without issue even though I had to work in the rain to do it. I wanted this truck on the road and my car is having some issues that need me to park it and work on it some. I have been driving the truck for a couple days and haven't been feeling very well.
Today I decided to pull the interior panels and install the seat belts. Well on the driver's side the retracting part was there but no belt coming out of it and the bracket that goes to the other end of the belt and bolts in the floor was broken and part still bolted to the floor. The passenger side was a little better, all of it was in the panel like he said, however the part where it bolts to the floor was rusted and wouldn't unbolt from the floor so it appears that the anchor was just ripped up out of the floor.
Needless to say I am not real happy right now. However I have titled and registered the truck and he has the signed title to my bike and I do not know if he has titled it yet.

Speedometer Going Crazy. 2002 Excursion, 5.4, Auto Transmission, 246800 miles. Put key in ignition and immediately noticed no odometer display. Put it in drive, Odometer began to register but SPEEDOMETER fluctuated wildly. Reading the posts as best as I could, I replaced the VSS sensor on Rear Diff, and no change in symptoms. I don't want to replace sensors just to replace them.

I have a 2000 6.8L V10 Ex, and I'm currently working through the last thing on my "to fix" list. The truck has 37" tires (Nitto Mud Grapplers), and at freeway speeds the speedometer is off by 10mph. If it reads 60mph, I'm really going about 70mph.
I thought the solution was to order an SCT flash tuner, so I purchased one with tunes from 5startuning:
**1. SCT 7015 - X4 Flash Device with Choice of 5 Star Tuning Custom Tunes - 5 Star Tuning
I choose the correct Revs per mile for my tire (560), but the speedo is STILL 10mph off at 70mph.
No changes that I made to the tire size or axle ratio made any difference. It always read the same amount off. The SCT X4 flash tuner wasnt able to change the speedo on the 2000 Ex's.
[URL] ....
My question is this: If both of those tuners plug into the exact same port, and use the same parameters, why is it my X4 tuner can't change the speedo, yet this other tuner is able to? It doesn't make any sense to me. If the X4 truly cannot change the speedo of certain model years, there should really be a disclaimer about it. Feels like a bit of a rip off since the only reason I purchased it in the first place was to correct my speedo...

I have a 2001 chevy silverado 3500 6L gasoline engine.
I have been getting a P0307 random multiple misfire #7 on and off for a few months now, occasionally the P0300. Check engine light comes on when I am going up hills, often under heavy load and sometimes when the truck is cold in the morning and the truck starts to run rough until the code clears, which it does pretty quickly usually. I have replaced coil, crank sensor, cam sensor, fuel injectors. If I unplug the battery overnight the code will be cleared and the truck will be running just fine the next day.
