Ford F-150 - 1997-2003 :: Transmission Shifts Hard / OD Light Flashing While Driving

I have an 2003 F-150 4.6L with a 4R70W transmission, the speedometer goes crazy while I drive, the truck feels like it kicks in & out of overdrive, it shifts hard, the o/d light flashes while driving and I cannot use speed control. I have already checked the transmission fluid, changed the speed sensor, & the range sensor. After changing the range sensor the truck ran perfect for 3 days then the same problems.

Ford - Gasoline - Expedition :: 2003 Dying While Driving, Will Restart Eventually

My wife has an '03 Ford Expedition with 110k miles on it. It began dying while driving. Sometimes while moving. Other times when stopping or idling. She would describe that sometimes when it began acting like it was going to die she could "give it gas" and it would revive, other times that wouldn't work. It would usually restart after one or two tries. Our local mechanic did a tune up and replaced a coil. During the trip she began hearing a sound of "metal shredding" and the car died and wouldn't restart. She had it towed to a ford dealer. They replaced the IAC valve.

After that the dying would continue but instead of dying right away it would "lose acceleration, and eventually die within a few seconds" Took it to another ford dealership and they replaced the fuel pump and relay. It would work fine for a few weeks and then start dying again. Another local mechanic noted the error code P0231 "Fuel Pump Secondary Circuit Low" He kept it for a few weeks and was able to get it to die for him once but not again. The dying continued. Sometimes it would work great for weeks, other times it would die continually on the same trip. Took it to a 3rd dealer and they couldn't find anything wrong.It dies in the cold and in the heat. Usually after driving at least 20 minutes into a trip. Once it dies once it will typically continue to do so until resting for a day or so. Sometimes with a full tank of gas, sometimes with a low tank.

Ford F-150 - 1997-2003 :: 2002 - A/C Causes Rough Idle And Stall / Sputter And Die On Restart

I have a 2002 4.6L FX4. When I run the A/C for an extended period (say 15-20+ minutes), it will start to cough and sputter and eventually just die. It will restart but run rough and cough, sputter, die.

If I turn off A/C and let it set a while, it runs fine. No check engine light. Possible EGR problem????

Starting - Gasoline - Geo - Pump - Metro :: 1997 - Stalled Driving Up A Hill / Won't Restart

I have a 97 Geo Metro two door that just stalled on me one day driving up a hill. It was low on fuel and so I thought it might have just ran out of fuel. I put more fuel in it but it would not start. I had it towed back home and disconnected the hose out of the fuel pump to see if any fuel would spray out. It did not. This lead me to conclude the fuel pump is bad. I replaced the fuel pump but this still did not fix the problem. I had an electrical guy looking at it run a bypass wire to the fuel pump and it still did not work. His conclusion was that the ECM is bad. Does this sound like a logical conclusion?

Ford F-150 - 1997-2003 :: No Restart / Clicking Noise Coming From Behind The Fuse Panel When Turn The Key

I have a 1999 f-150 and am having a problem that I cannot pin down . After starting the truck and running it for 10 min or so I shut it off and it will not restart again for approx. 3-4 hrs . When you turn the key there is a clicking noise coming from behind the fuse panel . Also the truck will not start if temp outside rises above 80 degrees . Is there a replaceable relay under there or is it the computer module ? Battery is new .

Ford F-150 - 1997-2003 :: Random Interval Engine Stops With Short Delay To Restart - Code PO231

I have got the most aggravating electrical gremlin possible. For over a year now, the truck intermittently just dies. Mostly it happens about 2-3 mins after start (every couple weeks or so), then takes a couple of key offs, then back ons to restart. But it does restart and then runs fine for a time.... 2 weeks ago I was rollin' down the road and hit a pothole, and whammo, she died, and wouldn't restart. I thought, "great it was the intertia cut-off going bad." I had it towed to the shop where they did some diagnosis and told me it threw a PO231 code.

The tech then said he was doing the diagnostic manual directed test, and swapped out the fuel pump relay, and it started right up. New relay, out the door. A few days later on the way to work about 2 - 3 minutes after start, she dies again. I hang my head, say a curse word, and key it a couple times, and it starts back up and runs fine. Presently speaking she's back at the shop, but the owner, who's a straight up dude was loath to take her back, because it was running fine at the time.... I've got to figure this thing out before I drive it off a cliff.

Truck -- 2001 7700 XLT 5.4L 88K miles

Symptoms -- Random interval engine stops with short delay to restart, 1 hard bump engine stop with no restart. PO231 code (after the hard bump no restart). Didn't check it previously (wasn't aware there were "soft" codes).

Troubleshooting to date -- 1 new fuel pump, 1 new fuel pump relay.

Only things left are the inertia cut-off switch (which apparently don't go bad that often), and the wiring itself/connections to the different components....

Ford F-150 - 1997-2003 :: Hard Downshift From Overdrive

2000 5.4 4x4. 104k miles. Extended cab. Heres the issue, when you're at that spot on a slight upgrade and the tranny should down shift out of overdrive it will downshift kinda hard. Sometimes it does this and sometimes it wont. Its driving me nuts. I thought maybe change the fluid and filter and see what happens, but a tranny guy that I don't know from the other guy said dont waste your money its more than likely a broken spring behind a piston. I put a new motor in this truck about 10k ago so I can wrench. It did this before the motor swap too.

Ford F-150 - 1997-2003 :: 2002 - Hard To Start When Warm

I have a 2002 F-150 4.2L that is hard to start when warm. Cold starts are no problem, except in the below 0 F stretch last winter. Also when it is a hot start it is not an issue. Only when it has sat for a few hours does it have an issue. The following is the list of things that have been done.

- New Plugs,
- New Plug Wires,
- New Coil Pack,
- New Fuel Filter,
- Clean Throttle Body,
- Clean Mass Air Sensor,
- Clean Idle Bypass,
- Replace EGR Vacuum Control Switch,
- Manifold Leak Repair (Ford Dealer),
- Throttle Body Stop Adjusted for more idle speed,
- Check fuel pressure (40 psi key on, drops to 35 psi static).

Ford F-150 - 1997-2003 :: Truck Shakes When Accelerating Hard

Its not the tires/wheels. I just had them balanced. It only shakes when hard accelerating. If I am easy on it, then smooth as can be. It gets worse with the RPM of the engine. I am thinking its in the tranny.

It still shifts smooth and I have been pulling 17 mpg on the interstate with it. So I know its acting correctly? Could I have blown something in the trans or ballooned the torque converter?

It just started the other day, I drove about 350 miles on vacation and noticed it when I went to come home. Like i said it only shakes when you lay in to the throttle, and it gets kinda violent.

Ford F-150 - 1997-2003 :: 2001 - Binding Up Then A Hard Slam

My 2001 f150 4x4 with a 4r70w start slaming hard. Once at speed in overdrive it ran fine. Then driving around 25 it would be fine for a minute or so then I could feel it binding up then a hard slam. Then it would drive fine for a minute and do it again. Mechanical? Electronic? Torque converter?

Ford F-150 - 1997-2003 :: Vibration Under Hard Acceleration From Stop

01' Screw 5.4 4wd. Went camping this past weekend and it was the first outing for this truck our TT weighs 6k. When accelerating from a dead stop going straight I'm getting a rumble strip like vibration that last a second. If I take off very easy it doesn't do it. I've seen similar post but no definitive solutions. This truck has less then a 100k on it and so far I've changed the trans filter/fluid rear end oil with modifier and new spark plugs.

Once I'm rolling and hammer down it won't do it. It's more of a annoyance then anything.

Ford F-150 - 1997-2003 :: Brakes Hard When Motor Off Soft When On

My son just bought a 97 F150 with the back brakes blocked off. The front brakes had about full pedal when the was on. We changed the front calipers and brake pads. Bled them came back with great brakes (with back brakes blocked).

Then we found out the back calipers was none so we bought all new parts for both back brakes, found some leaks in the rear lines fixed them. Now we bled the brakes with the motor off till no air came out. Solid pedal. Then turned on the motor and the pedal goes down 3/4 of the way now easy.

Stops on snow good no tire sliding. Turn off the motor has solid pedal again.

Ford F-150 - 1997-2003 :: Rebuilt Tranny Shifts Hard When Going From 2nd To 3rd And 3rd To 4th

I just had my tranny rebuilt it doesn't shift hard all the time but it does from time to time going from 2nd -3rd and 3rd -4th I thought being new it may need to soak up some fluid so the bands can swell so I ask the shop that rebuilt it that question he said they soaked them as they rebuilt it so they should be swollen already then he proceeded to tell me it was electrical is he telling me the truth because the ck engine light isn't showing any faults and if it was electric shouldn't that have been fixed in the shop while it was being rebuilt if it was interior electronic?

Ford 6.0L Power Stroke Diesel :: 2007 F250 - Engine Gets Warm / Hard To Restart

I have s 2007 f250 superduty with a 6.0. Recently after the engine gets warm I have a problem restarting it. I have to turn the key to the run position until all sounds have stopped then I have to pump the accelerator to get it to start. Sometimes I have to repeat this three or four times before it starts. I have had the fuel pump rebuild and installed two new batteries. What I should be looking at.

Ford F-150 - 1997-2003 :: Hard Time Starting After Drive For A While And Shut It Off

My 97 f-150 starts up every time.........the first time. After I drive for awhile and shut it off it gives me a hard time starting. It just cranks over but wont start. If I give it gas it catches and tries to start but dies out right away after I let go of the key. Sometimes after up to 10 tries and 20 minutes later it starts up again, so far! Also there is a gas smell, but I am thinking that's because of putting the gas pedal to the floor. could it be plugs? i bought it with 180,000 miles on it. I pulled a plug and it does look pretty rough so I am going to change em tomorrow.

The parts store calls out iridium plugs. the guy told me any plugs will work. said the only difference is the mileage you get out of em.

50,000 on regular plugs
100,000 on platinum
150,000 on iridium

Not sure that's the case but I bought platinum. I changed the plugs and wires and it runs great now. stopped for gas yesterday and still had to put the pedal to the floor for it to start. only one try and it started tho...... what next?

Ford F-150 - 1997-2003 :: 2001 - Transmission Is Shifting A Little Hard When It Is Under Strain

2001 Super Crew
2x2 4r70w transmission
417k miles
4.6l

Transmission shifting hard when under strain. My truck has 417k miles and the transmission is shifting a little hard when it is under strain. For example going up hills when in cruise and such forth, no problems otherwise.

My question is kinda weird: Since the fluid has never been changed or added to for that matter (fluid level is correct) , should I change it now or just ride it out? It is still my primary vehicle and runs perfectly!

I have been blessed with this truck since I bought it new
No engine work
Changed DPFE a couple of times
Cleaned throttle body a couple of times
Couple of pairs of shocks
one O2 sensor
alternator

I know its a weird question but could putting new fluid in at this time make more problems?
