Ford Excursion :: 2000 6.8 Limited 2wd - Random Miss In Motor
Feb 19, 2013
I am a proud new owner of a 2000 X 6.8l 2wd with the 4.3 rear end .
I have had the truck for 2 weeks now . When I bought her , she ran a little rough but I expected as much after sitting for 6 months ... After driving her home I began to start a massive tune up , because she was acting like there was a miss ... The miss only started after she was at normal operating temp and at first only when at cruising speeds in overdrive on the freeway , it progressively got worse ... The miss became all the time once up to normal operating temp but will do it wether she is in any gear or even park .... Oh and the miss is NEVER at the same time it is always completely random ...
I have changed all 10 coils , all 10 plugs , the PVC valve , and I am changing the fuel filter this afternoon ... Other then that I think I can hear a vacuum leak , but I have tried spraying carburetor cleaner around the engine bay as instructed by a " ford expert " at the local auto parts store and I did not notice any change ... After I install the new fuel filter I am going to fill her full of 93 octane and add a bottle or 2 for Lucas octane boost as well as the Lucas injector cleaner ...
Other then these things I am at a complete loss ! This is my first v10 ford so I am a little at a loss ... Now if this was my wife's BMW 760 or my Lexus IS 300 I would not be having this problem.

2002 Ranger XLT 4WD 4.0.. I was passing another car at about 55 when they also started speeding up (go figure) so I floored it and got on around them but before I lifted I felt it miss, the CEL began flashing so I slowed to the speed limit and went on to work. The light flashed for about a mile then went out. So on the way home I floored it again close to home and the CEL came on again. Got home and put the code reader on it and all it had was a random misfire so I have cleared it. The truck has new plugs, wires, etc for a complete tune-up. I don't usually run at full throttle so don't know if that would be normal for the Ranger, the Ranger was my wife's truck for 12 years and now is my DD. Need to clear this up? Thought of changing the fuel filter in that is still the original one.

We've got a 2006 F150 with a 5.4 in it. One of the new kids was told to change the spark plugs, then when I went to start the truck the next day it was missing bad. Plugged in the Ford IDS, number 7 cylinder is dead. Only codes are for that cylinder misfire, and random miss on startup. So, I double checked the kids work and it was all fine. Tried putting a new plug in, didn't work. Moved the coil to a different cylinder to see if the miss would jump, stayed on number 7.
Used a noid light to verify COP harness was working, and it was. Put a new coil on it anyway since I had one, still missing. Used noid light to verify signal going to injector for the cylinder. Signal was good, replaced the injector for the cylinder. Still misfiring. Ran a compression test and the cylinder has good compression. The threads for the plug are fine, not cross threaded or torn out. The only thing I can think is that the PCM has gone bad in a way that its firing the injector/COP, but doing so at the wrong time some how.
Every other cylinder is running fine, O2 sensors fine. PCM isn't trimming anything back to account for anything, and if it was it would do it to multiple cylinders to keep the engine balanced. Cant think of any more tests, and I don't believe there is anyway that the airflow could be restricted to only 1 cylinder, but I could be wrong. Wanna try and solve this to keep from sending it to the dealer.

So i bought an excursion 3 or 4 days ago and yesterday I went to install a double din dvd receiver. As I was installing something shorted out and I blew the radio fuse. No big deal or so I thought. Got the radio in and replaced the fuse but then the X wouldn't start. Went through everything and found a 5 amp fuse and a 15 amp fuse blown as well. Turns out the 15 amp fuse is for starter motor or something. Well I replaced the fuses and they kept blowing. Unhooked the radio completely and still keep blowing and the X is still obviously not starting. Pulled every relay I could in hopes something would reset and nothing. Any clue what it could be at this point?

2000 Ex 5.4 v8
Had 2 coils go bad last week. Got them replaced. Today I am on the turnpike doing 70 and my oil light comes on and oil pressure drops all the way. No engine noises and temp is OK so I coast to the next exit. Get off and go to the gas station in the corner. Turn the truck off...
Wait a few minutes, when I go turn it back on it wont start. The motor wont even turn. It just clicks.
I notice smoke coming from the wire that goes from the starter relay to the starter so my brother comes and gets me and we go to the nearest auto part store and buy a new relay.
Replace it and try to start it, same thing. Just clicks and smoke. My brother gets under the truck and taps the starter as I try to start it, no go. I am fearing the engine locked up. But no engine noises, clicks or clacks or anything. Battery is fine as well. Any thoughts on what else I can try?

Hey everyone,
I've been shopping for a 7 seater with some decent gas milage and maybe room for dogs in the future and school buses are too expensive, heh. Would love to get a 7.3l Ex and I may have a chance now...but wanted to get your input...
A good mechanic friend of mine that owns his own shop, and a former ASE Ford Mech has a friend with a 2001 Ex Limited 4x4 7.3 w/310k. The interior and leather seats are in great condition, no cracking in the leather. They have never towed with it, mom drove it to shuttle kidos. He only wants about 5-6k for it, should I ****** it up or wait for something else, it seems like a great deal for a 7.3l.
There has been no mods and the front end was rebuilt by my buddy about 3 yrs ago. This would not be a daily driver but would get a fair amount of use with 7 of us on weekends.
thx

The X has 107K on the clock. I have a 6 quart after market aluminum diff cover installed with Royal Purple 75W-140 synthetic gear oil and no limited slip additive in the gear oil. When I make a left or right turn, I get this vibration like the limited slip clutch pack is engaging then disengaging. It is not a thump or thud but just a subtle vibration. I don't hear any noise but I just feel the vibration. It happens either going forward or backing during a turn and is more noticeable when pulling a load and turning. Going straight down the road I hear no noise and feel no vibration. I thought I would ask before I pulled the diff cover off.

I have a 1999 Buick Regal GS with a supercharged 3.8 liter engine and 161,000 miles. I bought the car off of my uncle and he said he would have to change plug wires every month to month and a half because it would start missing so bad. When I first drove the car it would quit on me at red lights and in parking lots, it only seemed to do it at low idle speeds. I live on a hill with a blacktop road and I had to give it a lot of gas just to pull the hill it was missing so bad. The plug wire had a lifetime warranty on them so I replaced them and it stopped quitting on me but I still had a bad miss at random but not as bad it would just be like hard jerks. I added sea foam fuel injection cleaner and had the fuel filter replaced. The mechanic checked the spark plugs and he said they were like new AC Delco. I also cleaned the MAF Sensor (the mechanic told me to and how) because the engine did not run steady at idle and it seemed to work that, but not the miss. Could my problem be the plug wires? They are carquest brand 7mm wires.

So I was talking to a guy today with a 2002 Limited diesel. I noticed that his truck didn't have radio buttons on the steering wheel. I thought all 2002 Limited had radio buttons on the steering wheel. The inside of his truck also had simulated wood grain in places that my truck (also 2002 Limited diesel) didn't have.

Installed the Riffraff gauge kit and the check engine light came on about 20 miles after install and the Ex now randomly has a hard jolting miss, just for a second then its gone. Took it about 4 or 5 times of the jolting miss then the check engine light came on.
Could something have been unplugged or could the manifold air intake heater delete be causing the light. Ran fine until the gauge install. I remember reading something about the ground for the manifold air intake heater being a issue if not care full. I could not get the dam thing off so tapped the end and left it. The ground post kept spinning not allowing the ground to come loose. This thing is becoming a pit I cant feed fast enough.
If I can figure this out before Monday that would be great. If not I am tired of dicking with it and am just going to take it in. Don't have a scanner that will read the codes so SOL there. Unless there is some way to get them off with a flashing light sequence. I would love to find out how to do that. I don't want to drive it anymore than I have to as if one more thing goes wrong with this dam thing........

I developed a significant miss on my '00 Excursion 6.8L yesterday and threw a P0306 code. Since the engine has 178K showing and I bought it used, I am planning to replace all the COPs and plugs.
Recommend one COP over another; motorcraft over Accel, etc.? Any preference for spark plugs?

I have a 2001 Excursion with the V-10. Two weeks ago, the upper nipple on the radiator cracked and I overheated. Was towed home and replaced the radiator with a quality aftermarket one. I then drove to the whiz wash and cleaned the antifreeze off of the engine.
Immediately I noticed a slight "miss" when cold, particularly when backing out of my driveway. I have no lights on the dash and it is throwing no codes. The miss gets much better (almost gone) when the truck is warmed up.

2001 V10 160000 miles.
1st happened Wednesday on way back. Temps all fine but had been in stop and go traffic earlier. Truck was on cruise and felt like fuel cut. I disengaged cruise. Throttle would keep it running and within 5-10 seconds it caught and ran fine.
Connected and reconnected all injectors, coil connections, tb and MAF connections. Nothing noted loose. No codes on OBD reader.
Drove around town last couple days no issues. Today towing three dirt-bikes about 45 miles. towards the end of the 45 miles. she stumbled as we crossed an intersection. Then caught and ran fine. Did it twice on way back home towards the end of the trip.
Had OBD reader in gauge mode with ignition advance, tp sensor, voltage and gallons per hour showing. None seemed to change when it stumbled.
Fuel pump is about 2 years old. Coils maybe 4 or 5 years old. Aftermarket. No codes on OBDII reader.

My dad has a 2000 F-150 with the 4.6L with 90,000 miles. He just had the transmission rebuilt 5,000 miles ago if that. It seems to miss between 45-55 mph when you have a little hill and give it some gas. Once its shifts out of over drive, it seems to be better. With over drive off, it does not miss as much. I know we put new plugs in it but don't remember how long ago it was. He bought the truck brand new.

Just hoping that there is something common that causes this problem. This thing can idle just as smooth as you could want one to and the next time it will have a dead miss, and the miss is not consistent. It may miss like three hits then be ok a little then miss a little. There is no CE light or codes. Again just hoping there is something common.

2000 VW GOLF 2.0L, manual, ~190k miles
Driving down the highway my CEL started flashing and the engine power dropped at the same time. I drove two miles to my destination and the idle was very rough and the power was still very low. The codes were P0300, 0301 and 0304.
The coil was replaced about 2 years ago. The plugs have never been replaced. About 2 weeks ago I had a solid CEL with the codes P1255 and P0422... I purchased a new ECT Sensor but did not yet make time to install it.
Could everything be related to the ECT? Or do you think there are multiple issues?

Got a 2001 F350 diesel auto, 295k miles.
It has miss when over 2000rpm. Below 2000 its smooth.
ICP has oil in sensor, ordered new one. Gonna change oil too.
CPS is new (not sure if its black or the other one). Starts idles and drives good otherwise.
Where should I look?

My father's 2000 F150 5.4L has developed an issue. But the issue only surfaces in it's last gear. As it shifts into overdrive it begins to miss and hesitate and bog. If you disable overdrive you never feel it.
I'm thinking an exhaust restriction. There are no trouble codes, no check engine light. I notice that the note of his exhaust changes as the vehicle warms up, sounds like it's being smothered. And the flow out of the pipe lessens.
My only issue is whether the EGR is causing it or the converters. Haven't seen them go bright red yet, but this has been going on for a good while.
I wanted to get a few opinions before I tear into it today. I'll do a vacuum test on the EGR valve and rescan the codes but don't wanna drive it and heat up the exhaust when i gotta disassemble it.

I have a 2000 F350 cab and chassis 4X4 with V10 and a 5 speed manual (actually it's a 4 speed with overdrive). My problem is the engine seems to have a miss in it. When I first start it in the morning it usually runs good for 5+ miles till it warms up then if I am not pulling a load I can hear what sounds like a miss but the truck accelerates fine. If I am pulling a load I can also feel a slight steady consistent shudder and I can tell the truck doesn't have the power it should and the gas mileage SUCKS worse than it use to.
I ran a bottle of Lucas deep clean through a tank of fuel and that seemed to work a little but I will still encounter the problem sometime during the day. When the miss seems to be gone I can hear a very slight pinging noise when I accelerate or pull a hill with and/or with out a load. The pinging noise I hear sounds like an engine with a distributor that is getting to much spark advance if you have ever experienced that before.
I purchased this truck used several years ago and I don't know what the PO did but the check engine light is not coming on and it doesn't throw a code. I put 10 new ford coil packs on it about a year ago so I really don't think it's a coil pack, but I could be wrong. To me it sounds like maybe it an injector problem????? I know there are several sensors on this engine and I am thinking maybe a crank position sensor is not working right but I honestly don't know???? Is there a way to test this sensor?
