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.

Ford F-150 - 1997-2003 :: Random Delayed Start When Truck Is Cold

Not all the time, but I've noticed it after the truck has been driven - shut off - then started again within a few min period. When truck is cold or has been sitting for an extended it starts no problem. By "delayed" I mean once I try to start the truck it takes a sec or two longer than normal before it cranks. Then when it does start it will idle very low for a sec or two then pick up and act normal.

So far I've done this to remedy it:
- new fuel filter
- new air filter
- cleaned MAF sensor
- cleaned throttle body
- seafoam thru vac hose

Only thing else I suspect is weak fuel pump but looks like it was act up all the time not just when the truck is started back to back. Truck has good power when running, I did a couple short blasts up to 80mph and everything was fine.

Ford Transmission :: 1992 E350 - Pinging Almost Tapping Noise As The Truck Was Stumbling

Started having an issue with my '92 E-350 box truck. I noticed a slight hesitation while driving which I thought was a miss from perhaps a plug wire jumping or something. It didn't do it all the time, just occasionally for a few seconds then would clear up. I looked for a bad wire at night but couldn't find anything so I said hell with it and changed plugs and wires, cap and all.

That didn't fix the problem. Progressively the problem has gotten worse. Then I started hearing a pinging, almost tapping noise as the truck was stumbling. Now I've noticed that the motor seems to be running fine as it does it which has led me to think it may be in the trans.

A little background on the trans. About 6 months ago the van started randomly conking itself out coming to a stop after a few minutes of driving. It seemed the trans was bogging the motor down as if it were locked together. If I put the truck in neutral coming to a stop it wouldn't do it. I went ahead and had my uncles shop flush the trans and he put some sort of synthetic fluid in it.

Since then the van has never done the cutting off thing again. All seemed well. Then this started. It does it from take off through all the gears even in OD. It almost feels as if someone is rapidly hitting the brakes. I thought maybe malfunctioning brakes however soon as I'm not pressing the accelerator it doesn't do it.

Today I had about 4000 lbs of wood in truck and it was a horrible trip. The truck would barely get up to speed. I unloaded the wood and on the way home it only seemed to do it going up hills so it seems any load on the truck makes it happen.

Does it seem I'm in the right area thinking transmission?? Being it happens in every gear would a torque converter seem to be a possibility. When I was having the cutting off problem I was told it sounded like the converter wasn't unlocking but the flush seemed to fix that issue.

I haven't pulled the pan to see if there's any surprises in it and I did the diagnostic check and there wasn't any problems found. Any other manual diagnostic checks?????

Ford F-150 - 1997-2003 :: CEL On - Heavy Pinging?

I have a 1997 F-150 4.6. I have a cel and a heavy pinging that seems to get better the colder the outside temp is. If I unhook battery , the rehook the cel is gone for a day or so and the pinging is much less, but in a day or so it comes back on and condition worsens.

Ford F-150 - 1997-2003 :: Pinging Badly When Towing

My wife's brother has a '97 F150 w/4.6L/automatic trans/4x4-OFF ROAD package. It's a standard cab, short bed (fleetside) truck.

It has 126k miles and he is METICULOUS about routine/periodic maintenance. He's owned it since new, has changed the plugs twice.

Is this a common issue with the '97 4.6L? He says he has tried using premium fuel to determine if it makes a difference. He said it worked but it still pings, just not as bad.

Ford F-150 - 1997-2003 :: V8 Truck Won't Start With Clicking Noise

It's a 97 with the 4.6 v8. I turn the key and the lights in the cab go out. A voltmeter on the battery reads 12.53 and doesn't drop at all when the key is turned. I took the alternator out and had it tested with a pass. The battery was replaced 2 months ago. I can hear the relay in the fuse box clicking away after the key is returned to the off position. Is my next step a new starter? Solenoid? Relay? This all just happened overnight. And it's only got 115,000 miles. The starter does not turn over...

Ford Ranger / B-Series :: 2003 2.3L - Pinging / Tapping Or Knocking Noise

My 2003 Ranger 2.3L When I purchased it in 2005 I never noticed this tapping noise until in 2007 when Tennessee forced 10% Ethanol added to fuel. That is when the noise started.

What this could be. I have since moved to Texas and found a station that sells Ethanol Free gas, but that does not remove the noise.

Ford F-150 - 1997-2003 :: Clicking Noise When Truck Start Cold

Start truck cold, getting clicking noise...sounds like valve but runs great. Warms up and clicking goes away. Remove #1 spark plug and it shows build up of whitish carbon. Will remove the other spark plugs and check. Also starting to use half a can of oil a week. No leaks that I can see. Oil pressure gauge shows high...always has. Also, open door and get out after driving and smell oil. Wanted to make it to 400k but might not be able to with this issue.

Going to do a compression check to see what else is happening. Still have decent power. If cylinder pressure is good would it make since to do just a "top end" rebuild (if it is a valve issue? Should i pull it and do a complete rebuild? What does white build up on spark plug usually indicate?

Ford F-150 - 1997-2003 :: Small Vibration On Dashboard And Noise Underneath The Truck

I have a 2001 Ford F150 with 165800 miles. I just had my power steering pump, PVC valve, and serpentine belt replaced by tire kingdom this Sunday 3/2/14.

After they replaced those parts, and I picked up the truck. I noticed the truck was making some new noises, these noises occur when I brake an it sounds like a small vibration on my dashboard and there is a noise underneath the truck. the sound also get louder when I roll up and down the window and run the ac. This had never happened before the repairs.

I took it back on Thursday 3/6/14 back to the mechanic and told them about the new problems. Now they said I had a brake problem. So they replaced the calipers, brake pads and rotors. But I still have the weird noise.

The truck still needs two rear tires a new high-end ac line and a freeze plug. Would any of these cause the noise underneath the truck or the noise in the dashboard or is there something else?

Ford F-150 - 1997-2003 :: Cracking Noise - Fuel Smell - Truck Broke Down?

My truck broke down on the freeway last night. I heard a cracking noise (metal breaking) and it sounded like a backfire. The engine was running fine, good RPM's. I rev it up and the noise got worse, It sounds like a bad lawn mower or go cart. I was also smelling raw fuel.

Could I have broken a exhaust flange or the manifold? It sounds like the exhaust is bad and not burning the fuel.

There were no codes or a check engine light. I only went 1/2 mile after it broke down. I had to tow it to a local shop.

It's a 2003 4.6 with 205,000 miles.

Ford 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 :: Truck Started Making Screeching Noise When Turn The Wheel And Moving At Slow Speeds

97 F150 4x4 around 200k miles on it, Drove the truck to town today and it started making a screeching noise when I turn the wheel and moving at slow speed's It is not the typical Ball joint squeak, and they were replaced about 6 months ago. I also get a clicking squeak going down the road, everyone in a while from take of ill get a slide grinding or crunching noise. Also noticed that when taking a curve to the right i feel and hear a slight Bump but I don't when turning to the left/

Also it doesn't have the typical grinding noise of a bad unit bearing, there is a slight roar but Pretty sure that it is just the aggressive tire's... I am about to go out and Jack it up and have a look at it to see what it was. Also if I loosen the Cv nut on at the Hub that would show me if there was any play in the bearing correct? since the cv should keep the bearing's fairly tight even if they are worn?

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).
