Ford F-150 - 1997-2003 :: Stall At Idle / Hesitation When First Pressing The Gas / Loss Of Acceleration
2001 F150 V8 4.6 Liter... I've been experiencing hesitation when first pressing the gas, stall at idle, RPM fluctuating between 1000 and 500 at idle and loss of acceleration. Had the truck read at autopart store and received a P0402 error and misfire is cylinder 8.
At this point, I've changed the the plug, COP, EGR valve, EGR Valve Solenoid and DPFE sensor and still have the exact same symptoms. I've also changed the plug for cylinders 5,6 & 7 as well. The check engine light is on, went off briefly after changing DPFE sensor, but back within a day.
Given the fact the error code is P0402 and some of the threads I've read, I thought the issue was centered around the EGR system, but I've replaced many of the components.
Ford F-150 - 1997-2003 :: Transmission Slipping Every Time Going From First To Second Gear
I have a '97 F150 4x4 with the 5.4L engine and automatic transmission. The tranny's been slipping on and off for a couple of years. It started when it was hot outside, I had been driving a long ways, and I was trompin' on the gas to pass someone. Still, the slips were rare. As it got worse during the hot summer months, I just minimized my long-distance travels.
I recently took it to a transmission mechanic. Like some of the feedback to posts in here, he felt it was a problem with the engine - because we had a bad EGR valve signal on the computer. (We still flushed the fluid. I later replaced the EGR and the DPFE. Another mechanic went through everything, replaced some valves that had something to do with the EGR, and feels the engine is 100% (and it runs very, very smooth). For those that will bring it up - I have replaced all of the coils (though it's been a few years). Having actually replaced some numerous times over the years, I can feel when one is bad (of course, the 'check engine' light as well). Lastly, we've replaced all bulbs in the dash so they are all working as well. Also, the transmission is not leaking. The computer system is giving us no errors/throwing codes.
After a couple of weeks, I happened to drive the truck a long distance one day and it started slipping. It got bad enough that it was slipping every time going from first to second gear. It would usually engage as I took my foot off the gas. Since then, because I haven't driven long distances, I have not had a problem.
The transmission mechanic thinks it's still an engine issue. He also mentioned a mechanical/electrical switch system on the side of the transmission (?). Give me a list of things to look at.
Camry :: 2003 - Power Loss And Hesitation Jumps Under Load
My 2003 Camry loses power and starts to hesitate or miss-like under load, but when cruising along not under load it runs smooth. There is no check engine light coming on.
I have changed the fuel pump and fuel filter in the tank.
I have changed the spark plugs.
I have added injector cleaner and fuel treatment to the fuel.
I have cleaned the air filter and air filter compartment.
Ford 7.3L Power Stroke (1999-2003) :: Transmission Slipping When Put It In Drive
My tranny is acting odd. I put in drive and seems to slip a lot in 1st, barely even move at some times. If I put it in 1st with the shifter it goes in and grabs then I can shift up to 2nd or drive and there aren't problems. It drives normally when not from dead stop.
Transmission has 50k miles on it since replacement. Fluid level is normal. I don't tow and drive it particularly hard. I will have to go back and look at miles since last fluid change. I should be right around 30k miles since last change.
Ford 7.3L Power Stroke (1999-2003) :: 2000 F450 4x4 Transmission Slipping
I have a 2000 Ford F450 7.3 4x4 dully with a PTO driven winch 108,000 miles. The truck has develop a transmission slip.
I have changed the transmission fluid twice and it drives better but it slips badly. I can drive it up to highway speeds but it has problems getting from 0 to 10 MPH. The transmission runs hotter then normal but nothing major maybe around 205 degrees
Do I need a complete rebuild? This is a beater truck that I use to tow mainly. It is not worth a major investment. I need the PTO gear and 4x4.
I have several 2000 through 2003 7.3 E350 and E450 short school buses. Does the transmission from these has a PTO gear? I am thinking of pulling the transmission from one of them and swapping it.
It looks like the transfer case just bolts to the back of the transmission; I believe that a 2wd van 7.3 transmission will work with the 2000 F450 setup.
Ford 7.3L Power Stroke (1999-2003) :: F250 - Transmission / Torque Convertor Slipping
My son bought a 1999 F250 Diesel about a year ago. The seller gave him receipts showing that the 4R100 had been rebuilt and a new T.C. installed 25k miles before the sale. The problem is that it is slipping. He says it started with 2nd gear, now it will hardly move in 1st.
Fluid smells a little burnt. We pulled the transmission pan expecting to find lots of friction material. It does not have as much as I thought it would, not as much as I have found in the the pans of the few other auto trans I have seen with worn out frictions. Below are pics of the inside of the pan.
Or, is it the T.C. that is slipping. I have never had a vehicle with a bad T.C. How do you diagnose it? I have experience rebuilding (GM) Turbo 400's and 4L60's. Never had a ford AT apart.
Ford F-150 - 1997-2003 :: Starts Fine Then A Day Later It Won't / Acts Like Not Getting Fuel
We have a 2003 Ford F250 Super Duty, gas engine. This will start fine, then a day later, it won't. Wait 30 minutes, then it starts.
Starter and battery are fine. It acts like it isn't getting fuel. Fuel pump? Filter? What else might cause this?
Ford F-150 - 1997-2003 :: Power Loss - Cannot Go Very Fast
I have a 97 F150XL 4x4 a few days ago i was driving and i started to lose power i had to take it out of overdrive just to maintain 60mph by the end of the day it took a good 45 seconds to a full minute to get up to 10 mph. I have been told it is the catalytic converter, anything that would cause this it has a lope when stopped at a light but is fine when in park it acts like its flooding when I take off from a stop but the faster I go after taking off the flooding feel goes away and just seems like a lack of power. That morning i put on a EGR vacuum solenoid and an o2 sensor...

I am working on a 2000 f-150 XLT 5.4L 4x4 Automatic. It tries to crank over but acts like its stuck. things done: New starter, new battery, fixed connections. I can turn the crank counter clock wise but won't turn clock wise. Not sure if i should say the engine is bad or could trans be stuck? Heard 5.4L's have timming chain issues. Is that true? Point me in a direction and i'll go forth.

View 8 RepliesFord F-150 - 1997-2003 :: Incredibly Loud Noise Under The Hood And Loss Of Power
My 99 F150 4x4, 5.4 triton all of a sudden got very loud and has a loss of power. To me, it sounds like a cylinder is straight open to the atmosphere. I at first thought a spark plug blew out or an injector somehow came dislodged but I checked and everything seems ok. It's coming from the passenger side somewhere but is so loud under the hood I can't tell exactly where.
I took the valve cover off to see if a valve is stuck open or something, but I don't really know what I'm looking at as far as internal engine goes. I turned the crank by hand with a ratchet and the valves seem to follow the cams, but I've never inspected valves before so don't really know what to look for. What could be causing this loss of power and incredibly loud noise?
Ford 6.0L Power Stroke Diesel :: Check Engine Light Codes P0405 And P0404 - Hesitation And Loss Of Power

It still has a hesitation and loss of power , although better than before the Change.
Ford F-150 - 1997-2003 :: Skipping / Rough Idle And Loss Of Power - Misfire On Cylinder 4
Replaced the spark plugs and wires a couple months ago. Started skipping yesterday throwing the #4 misfire code so I replaced the coil pack, reset the check engine light but it's since came back on and has a rough idle and loss of power. By the way, it's a 97 F150 4.6L 4x4 with 200,000 miles.
View 4 RepliesFord 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.

Due to being low, and taking my splash guards off to put on my skid plate, in heavy rain, my belt I guess gets wet, slips and I lose power steering. I can hear it screech.
I didn't think that would be the case for snow, but sure enough after plowing through my driveway to go to work it was slipping screeching and loss of power.
Ford Ranger / B-Series :: 1998 - Random Misfire / Power Loss / Hesitation - Code P1131
Ok I've been plagued with this very random misfire/power loss/hesitation problem going on a couple of months. You could drive the truck anywhere from 50-300 miles without having an encounter of this problem. It seems to do it now mostly on contiguous long trips over like 30 miles. It one time threw up a P1131 code which quickly went away on it's own. This is a list of stuff that has been recently changed: plugs, wires, coil packs, air filter, pcv valve, fuel injectors, tps, idle air valve, MAF cleaned, fuel filter, and egr valve.
I sprayed with brake cleaner for vacuum leaks around the intake tonight after driving a continuous 50 mile round trip it messed a few times on the way back. When I sprayed the EGR valve mounting area it idled rough when it was hit with brake clean and idled up. So there's a leak there. Or is it stuck? It will be driving normal and usually when you come to a stop the engine will start missing really bad and then when you take off there's no power at all. You keep your foot on the gas and eventually it will feel like all the power is just turned on.
If it does it while you're driving highway speeds it will feel like you've lost a cylinder but it's not as dramatic as when you come to a stop and it starts missing. I can't be 100% but I don't think the EGR wasn't leaking before I replaced it and it was still doing the same thing. I'm wondering why the Check Engine Light won't pick up an obvious misfire when you can you actually feel it. And why if it was the vacuum leak would it only start doing it after many miles of driving?
Ford Super Duty (1999-2016) :: Hesitation / Idle Rough / Stalling Sometimes - Power Loss
Here is this wonderful 5.4 's issue now, sometimes it will idle rough, sometimes it wont. sometimes it feels like it wants to stall, other times not. if im driving about 30mph up a hill around 1700 rpm, the engine feels like a bucking horse, it will kinda want to produce the power, but cant seem to find it till the trans drops to a lower gear. With this engine power loss is unacceptable because it came out of the factory with no power, i cant afford to loose more.
there is no check engine light. its been doing this on and off for a week. i dont drive it much, may 15 miles a day. i thought maybe it was bad gas , i had it sitting for a month, but since then ran almost 2 tanks of gas through it. Seems to act the worst when driving it, then letting it idle for 5 mins, then drive it again, that's when its very noticeable. no smoke from exhaust, no mixing of oil and anti freeze, plugs are a year old, filter is new.
