Ford 7.3L Power Stroke (1999-2003) :: 2001 F350 - Power Loss And Almost Shut Down At Random Times
I have a 2001 F350 7.3 the truck will at random times loose power and almost shut down. A while back I had an issue with the uvch plugs and changed that out. Truck ran fine till I got some dirty fuel from a diesel tank at my friends farm. I did the hutch mod cleaned the tank and now have a frame mounted screw on filter before the pump. I cleaned the fuel bowl and changed the filter. Fuel pressure stays at 59psi and drops to 56psi wot. The truck is tuned with an edge programmer. After these mods the truck ran awesome for over 2000 miles. Now it has the above stated problem. I have fuel and hpop guages along with egt and boost. During the problem egts will increase rapidly and it seems like it is starving for fuel.
Hpop gauge reads 3300psi or above during wot and shows good pressure during these mishaps. I have auto Enginuity and I get a different reading at wot of only 2600 psi. The hpop gauge is tapped into the icp sensor per instructions and has been installed this way for a while with no issues. The tune has been on the truck for over 40000 miles. The only thing that I can come up with is it will occasionally throw a p1211 under wot or pulling my Gooseneck Dump Trailer when loaded. However it acts up sometimes and doesn't throw the code. Sometimes you can shut it off and start it back up and it's fine other times it will last for the whole day. My only guess is low pressure from the hpop but I don't reflect this from my gauge only on AE at wot. Wouldn't a bad pump act up all the time? Am I correct to think it is just the ipr?
Ford - Ranger :: 1997 - Clunking / Rattling Sound In Manual Transmission At Random Times
I have a '97 Ranger with about 120k, 5 spd manual transmission, 2wd. For the last 2-3 months I'm hearing and feeling a clunking or rattling noise (I can't decide which it is) coming from the rear of the vehicle at random times.
I can't really predict or find a pattern of when the noise will happen, but it seems like it is most likely to happen when I'm either accelerating up a hill or when I'm braking relatively hard. It happens whether the clutch is in or out. Doesn't seem to matter. It does NOT happen when idling, only when traveling. I don't ever remember it happening at highway speed (65mph).
If I have my hand on the stick shift I can feel the shaking / rattling as it happens. There seems to be no impact on the performance of the vehicle - no additional trouble shifting into or out of gear, accelerating, or anything else.
On a recent trip I towed a 1,000 lb trailer and I did not feel or hear the noise at all during that trip (about an hour each way). Any guess as to whats going on?
Elantra XD (2001-06) :: Random Sputtering - Fuel Filter / Pump Going Out
I have a 2004 Hyundai Elantra with 96,000 miles and a brand new 2015 Hyundai Elantra.
It had been randomly sputtering for a couple of weeks before this and I thought that the fuel filter/pump was going out. So, I replaced that and when I turn the ignition on gas squirts out of the fuel pump so I know that is working. I then replaced the spark plugs because I don't think they had ever been replaced, but it still won't start.
When I turn the key everything sounds good, but it just won't start. I am trying to avoid having it towed to the shop until I exhaust the ability to fix it myself.
Ford F-150 - 1997-2003 :: Driver Door Unlocks Multiple Times When Turn Off Key (6 - 10 Times)
2003 F150 Super Crew 5.4
When I turn off the ignition, the drivers door lock unlocks or pushes the arm through the door for up to 30-60 seconds over and over again. I would say like 10 times and it is annoying as hell.
Is the only part in the door that controls this the actuator or is there something else that can be doing this?

I had been having battery issues with my 97 ford f150 4.6 liter for the longest time, thought i had a short under dash, i pulled entire dash out, disconnecting bat first of course, and inspected all wiring harness connections and fixing my issues and putting it all back together. now with new bat and all put back together i am now getting the airbag light flashing 5 times then 2 times (error code 52) i know it has some thing to do with power failure or backup battery, but now with the new battery in i cant seem to get it to reset. How to do this?
View 3 RepliesFord - Focus :: 2003 Runs Rough At Random Times
My son drives a 2003 Ford Focus with 183,000 miles on it. At random times when he starts the car, the engine runs very rough at idle speed but when he drives away, it runs fine until he slows for a stop sign/turn, etc. and the engine is at idle speed again. When this happens, the engine runs so roughly, that he loses vacuum to the brakes and his brakes stiffen dangerously. The car may not do this at all for a couple of weeks of driving, and when it doesn't do it, it runs beautifully.
Also, it only runs like this if it does it from start-up; it never idles roughly in the middle of a drive in which the car started normally. I have changed the spark plugs and wires, PCV valve, fuel filter, and air filter, but it still goes through this about once a week. I bought the car used just a few months ago and it had just had the valve cover gasket changed because the valve cover was leaking.
Malibu :: 1997 Chevy Misfire At Random Times And When Under Heavy Loads
I have a 97 Chevy Malibu V6 3.1L with 92k miles on it, a couple weeks ago i started getting a misfire issue. The car would start to misfire when under heavy load such as accelerating up a hill. The local auto parts store diagnosed it with code P0302(cylinder #2 misfire). I started by replacing all of my spark plugs(ACDelco Platnum) and wires. This seemed to fix the issue for a day or so, after that the misfire worsened. I would misfire at random times and when under heavy loads. This caused my transmission to keep shifting up and down followed by the all to familiar hot/melted plastic smell of overheated transmission fluid. This continued on for a few days as it got worse.
The car than started to misfire heavily all the time. I took the car to another auto store and it pulled up codes for Random/multiple misfire. I then took my car to a mechanic for a full diagnostic, their computer said their was a misfire on cylinder #1, as-well as a bad spark plug wire on #1( He found this by getting shocked while wiggling the wires on the coil pack) and told me to replace the bad wire. I replaced all wires again and the problem remained. i took it back up for re-diagnosis and they then said it was a bad coil pack. I replaced the coil packs and the problem still remains.
Santa FE SM (2001-06) :: 2004 Hyundai 2.7L - Loss Of Throttle At Random Times
I've been having trouble diagnosing a loss of throttle at seemingly random times. Sometimes while driving, especially after driving for more than 20 minutes or so, I will experience a hesitation while on the gas pedal as if I have taken my foot off the gas. It makes it impossible to drive until I pull over and unplug my TPS and then I can drive fine in manual mode. Then the next day I can plug my TPS back in, drive around fine for a bit before the hesitation happens again and then I have to unplug the TPS again and drive in manual mode. It doesn't make sense to me why it takes a bit for this hesitation to begin and why unplugging the TPS and driving in manual mode seems to fix the problem.
I've recently replaced my crankshaft position sensor, idle air control valve, purge control valve solenoid and TPS. When I recently placed the TPS, the hesitation problem and another problem I've been having recently, a high idle in park, seemed to be fixed, but then the hesitation problem popped up again. When I unplug the TPS, the hesitation disappears and I can drive fine but the high idle in park problem is back! I'm suspecting some sort of wiring problem to the TPS. I just went on a 100 mile camping trip in manual mode no problem, but I can't be driving around forever with no TPS.
Passat (B5) :: 2003 Won't Start At Random Times
I have a 2003 Passat and it won't start at random times. The battery would loose all it's charge but has the battery tested and it was fine. Hooked a voltmeter to the battery and with engine off got 12.4v. Right when I start it it would drop to about 10.6-11.1v. While running it would show 14.1v and with all accessories on and running at about 2000rpm it would read 13.6v.

F150 has the 5.4L w/ the auto. 59K on the ticker. This "spuddering" type problem only happens when in overdrive. Mostly highway and when starting to pull up small hills. The symptom is a slight jerking and "spuddering" feeling. It goes away with more rpm's and some acceleration. I've tried injector cleaners and 91 octane just for grins, nothing works. Is this a possible COP issue?

View 3 RepliesFord F-150 - 1997-2003 :: 2003 - Got Code U1262 - Random Misfire?
I have a 03 F150 with a bi-fuel 5.4 engine an it has 195000 miles. I have had trouble for some time now with misfires. I bought the truck in october of 2011 with 125000 miles and replaced all the coils and spark plugs because it was misfiring badly will running on CNG. It was fine on gasoline and never had any codes. After I replaced the plugs and coils it ran fine on CNG and gasoline.
This summer 2013 it began missing badly at highway speeds only when running on CNG. If I accelerated the miss would go away until I was light on the throttle again.I checked the misfire count and found the bad cylinder and replaced a coil. Then a day later same thing on another cylinder. I swapped a coil from another cylinder and problem went away for a day. Eventually I chased the misfire around all the cylinders on the engine until I had ended up either replacing a spark plug or swapping a coil on all the cylinders. And I still had a misfire. It seemed to be worse on days with temperatures above 90 degrees. Eventually I got it to stop misfiring.
So now 5 months later I am back again with a misfire. This time it is misfiring on both gasoline and CNG and under any throttle conditions, except coasting. I have no codes. And the misfire monitor is sending me around the engine again. I have replaced a spark plug in two cylinders and swapped 4 coils.
I'm ready to buy all new coils, but I want to be sure that it is not a waste of money since the old ones only have 70000 miles on them.
Two days ago I had the misfire monitor saying #4 in the evening and the next day without me having done any work on it it was saying #6. Later that same day it said #7 and I still hadn't done anything other than drive the truck.
I checked the connections at the firewall on the drivers side with the three large plugs that are held in with a 10mm bolt, they looked fine, no corrosion or burnt pins. I checked the connection at the ACFM which also looks good. I will check the connection at the PCM in the next day or so.
Some other problems that may be contributing:
1. I occasionally get a U1262 code (scp fault)
2. Sometimes when I check the misfire monitor it only shows 7 cylinders, sometime 9 cylinders. I am using an Innova 3160 scanner.
3. I have either a leaking valve cover gasket or leaking head gasket, because I have oil dripping from the rear bottom corner of the passenger side cylinder head right above the exhaust pipe.
Ford F-150 - 1997-2003 :: Random Misfire Now Won't Start
I have a 1997 F-150 2WD 4.6L V-8 that began having random misfires as I would drive. I was planning on going out today to get the new plugs and coils however when I got off work and pulled into my drive something happened when I went to leave the truck wouldn't even crank it just made a clicking noise. The battery has full power (the radio ect. still works). I am hoping that the problem is with the coils and plugs but if not ...
View 5 RepliesFord F-150 - 1997-2003 :: Rear End Bounces Only At Certain Times
I thought my brakes were sticking........don't think thats the issue. My rear end bounces....you can see it, and its only certain times...mostly when its hot, or I've been driving for a while (an hour maybe)
I have been taking notes on the symptoms, and finally got some noise today. When the rear end starts to hop it sounds like you are riding on rims and it will actually slow the truck down if you let off the gas.
The brakes aren't hot beyond reason, and I've noticed that it occurs mostly after making a sharp turn???? Or a fast medium turn such as a quick merge.
I think something is either coming loose in the rear or ?????? Not sure Also, when I pull my camper I haven't had it happen yet.......may be a coincidence.....? Or the fact that I take turns slower when its attached.

View 3 RepliesFord F-150 - 1997-2003 :: Random Pinging Noise From Under The Truck
I just picked up a 1999 F150 5.4 with around 19k miles on it. Truck is in mint condition, stored in a heated garage since new. Before we made the deal I checked everything out pretty well including checking all the fluids, test drive, other usual stuff and didn't notice anything out of the ordinary. However, today I went for a short ride with the windows down I noticed a random pinging noise from under the truck. At first I thought it was a few small rocks bouncing off something metal under the truck, however it continued to do it randomly for the next 5 minutes. I would say I hear a ping every 15-20 seconds randomly. Doesn't matter if it's idling or under load, happens about the same either way. Aside from this, truck starts and rungs great and no error or warning lights have kicked on.
When I got home I started the truck back up and climbed under to see what it was. I found that the noise is coming from the exhaust system, mostly heard at the catalytic convertor. It resembles the metal expanding kind of ping, but I think its actually originating at the engine and the noise is just carrying through the exhaust system. I then went back to the engine bay and could hear the same random ping, just much quieter. I don't know the condition of the fuel, but based on the low miles I haven't ruled out a bad tank of gas. Only other issue with the truck is there is a bit of rust and corrosion on the inside of the exhaust tips and up into the exhaust pipe. They are still shiny and silver on the outside, just a little rust buildup on the interior of the exhaust. Hoping it's just the last 1' or so that is rusted
Ford F-150 - 1997-2003 :: 2000 - Speedometer / Gauges Going In And Out At Random
I recently purchased a 2000 F150 Regular Cab Work Series with the 4.2 V6 4x4 and an automatic transmission. It has what seems to be an electrical issue where the speedometer and gauges come in and out seemingly at random. All of my fuses are good with the exception of Fuse 1 in the fuse box under the steering wheel, which will blow every time I put a new one in. It seems like there is a short in the wiring for the radio? However Fuse 1 is supposed to control only the audio, and I'm not sure why that would be an issue with the gauges.
When they come on, everything seems to work just fine. Also, even when they go out and I have the headlights on, both the gauges and the car stereo will be backlit with the green glow.
When I turn put the key in the run position, the gauges will come on and remain on for a random amount of time after I start the engine, then will go out and come on at random. When the gauges go out so will my check engine light (code P0460).
Ford F-150 - 1997-2003 :: Truck Has Random Misfire Code
I was involved in a light accident over the weekend. I was hit in the rear by a Prius which didn't do body damage except for the 7 blade harness for my trailer towing. But, now the truck has a random misfire code. You can feel the truck jerk when you go up any grade. We changed the fuel filter and dumped in some cleaner already. One guy says its fuel and one thinks its coils. It is a 2003 F150 extended cab 5.4 with a nearly new motor. The truck has about 175xxx on it and I have had it for about 40xxx. I have not changed coils. We did check the inertia switch on the passenger side and it was not tripped.
