Ford F-150 - 1997-2003 :: Bad Miss Under Acceleration Below 2500 RPM
I have a 97 f150 with 4.2 4x4 auto. I have a bad miss under acceleration. if i ease on the gas no problems. stomp it and it chugs and pops back thru airbox til it gets to 2500 rpm then clears up. If I shift it manually and keep rpms up its fine till it gets below 2500. I have replaced spark plugs, plug wires, fuel filter, upper and lower intake gaskets, cleaned injectors, new air filter and cleaned o2 and mas sensors. Had vacuum system checked and was told all good.

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.

I recently inherited a 99 Expedition 5.4 with 90k miles. I'm trying to fix it up so I can sell it. Like the title states, the truck runs rough but there's no check engine light on. I did some research and ended up replacing the PCV elbow and that made it run better for a while but now it's back like it was. It won't die, just a really rough idle and a miss while driving. I imagine it's probably a (or a few) coil pack(s), but I have no way of knowing which one(s) to replace. I would think that would illuminate a CEL though. I'm also having problems with the AC. Upon inspection, I found that the compressor clutch assembly was completely gone from the front of the compressor. I replaced the whole clutch assembly, then voided the system of Freon and refilled it to spec, still no cold air. The compressor clicks on and off like it's low on Freon but it can't be. I'd just sell it as is but in south Louisiana a working AC is a huge selling point!

Alright so I have an 03 5.4 with 144000 miles. once it warms up to temperature it has a miss and low end power is low and no fuel mileage gets 12 to 13 if I'm lucky. From idle to 3000 rpm its doggy get it over 3000 rpm it runs great. All new plugs and coil packs. What it could be. When the motor is cold it runs great has most its power.

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.

Engine will start and run but will miss in a pull and die sometimes but will start back, we hooked it to a scanner and it said (intake wiring) it wasn't a dealer hook up just a gas station garage, we have already done plugs and wires.
View 2 RepliesFord F-150 - 1997-2003 :: 1998 F250 - Transmission Shudder Or Engine Miss Below 10MPH?
I have a new to me 98 F250LD with the 4.6/4R70W. I have maintained this truck fro my FIL as best as I could get him to spend (neglected). Filter and fluid replace with Mercon VI last year due to 2-3 shift slip.
He gave me the truck after it would not climb a hill, just hit stall speed and would not move up a steep hill, as I understand it. I put Seafoam trans tune in hoping it would free up sticky solenoids or valves in the VB.
I finally got it registered in my name and drove it to work and back today. After about 25 miles highway driving it shudders pretty bad trying to climb a hill at low speed.
It seems to me that at this low speed, torque converter lockup should not even be a possibility. I do not have COP, but rather a single coil pack. I replaced the wires and plugs for Dad a few years ago, but some shady shop later told him that I didn't replace the left rear (to make an upsale I suppose). Not sure what they may have done in there.
I have scanned with my ELM 327 and Droid using Torque Pro, and the only Fault is EGR flow.
Ford F-150 - 1997-2003 :: Slight Miss / Rough Idle - Hesitation Or Stumble On Acceleration
2003 F150 5.4 72852 miles
I have a Rough Idle & sometimes a hesitation or stumble on acceleration. I cleaned the MAF & IAC motor & Air & Fuel Filters are new. I got a 20890 scanner & ran test 6 53 as suggested in many posts by BlueGrass. Here are My results & what They Convert to.
1 00F5 .3675
2 0051 .1215
3 0000
4 0000
5 00A3 .2445
6 0000
7 0000
8 0000
I'm guessing the cop's are ok & probably need plugs? I was hoping to just swap a coil. Too cold to do plugs & truck won't fit in my garage.
Ford F-150 - 1997-2003 :: Starts Perfect After A Cold Soak But Then Miss / Sputter And Loss Of Power
1997 F150 4X4 4.6 engine with 285,000 miles
Truck was running perfect down the road, then suddenly it lost power and started missing at all RPM ranges. So i keep driving another 6 miles and then POOF the miss is gone and truck runs perfect. Couple hours later i hop back in it and its running good and then suddenly it starts missing and loosing power again except this time it never started running good again. Never did throw a CEL.
I hooked up my SCT Tuner (for my F250) to check for codes and came up with P0171 which indicated one of the banks was running lean, but no missfire codes. Did a search on here and learned the common problems(vacum leak) of that code.
Found the vacum leak at the PVC elbow, so i replaced both ends of the plastic tube.
Pulled the throttle body elbow and cleaned out the clogged up EGR ports.
Put a new air filter in and took the MAF out and cleaned it with MAF cleaner.
Put it back together and it idled way better but still ran like crap with the bad miss/sputter. Ran it down the road a few miles and came back thinking of the catalytic converter, i crawled underneath and it was glowing red. It does run and feel like the converter is stopped up but if i have a dead miss and dumping fuel wouldnt that make it glow red to or no? Still no CEL and now no codes.
Also i held the engine at about 1000 rpms where i could here the miss good and unplugged the fuel injectors one at a time to see if that made a difference. Each one i unplugged made it miss worse, so wouldnt that tell me that all 8 cylinders are firing?
And i changed the spark plugs (motorcraft) 250 miles ago.
So it still cranks and runs smooth after a cold soak overnight and then after a mile of driving or less it starts the dead miss/sputter and loss of power.
Ford Ranger / B-Series :: Random Miss At Full Throttle
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.

I have a 2001 F150 Supercrew. On the passenger door, the courtesy light no longer comes on. It's the light on the door (not the doom light). If I open any of the other 3 doors, all of the lights come on including on the passenger side so I know the bulb is good.
I looked for a door switch, but did not see any along the door or frame of the door. How do I go about fixing this?

Ford F-150 - 1997-2003 :: 2001 - ABS Brake Light Stays On?
My 2001 F150 has the ABS light on. I can startup and it runs thru the continuity test, light off, in park, no problem. Push on the brake pedal, no problem. Put it in gear and the light comes on, before you start to roll. Should mean its not the speed pickups, i checked them for ohms and 5 volt supply to each. I ran the scanner and got P0703 on the extended codes.
That normally means bad pressure switch on the brake booster. I knew that would effect cruise control and external leaks can be a problem, but could that be related to the 703 code ? Both "brake" related ? I am tempted to buy a switch and install. I do have the factory recall harness on the switch. And check for continuity thru the switch. Has continuity, but only a few ohms, not sure what it should be.

The odometer light turns on and off (mostly off) and seems to be getting worse. The repair shop I go to said its a dealer item and they usually send them out to a specialized shop, the dealer said replace instrument cluster. I may not be the best but I would like to try a few things before I shell out the money. I read that it may simply be the connections at the Instrument cluster plugin which might just need cleaning, read another fix which involved Pencel soldering, Cold Solders on the instrument clusters circuit board.
