Ford F-150 - 1997-2003 :: 4.2L V6 Hard To Start / Occasionally Running Rough And Losing Power
I recently bought a 4.2L V6 2003 F150 with only 20,350 original miles. This car belonged to an older gent who barely used it, then passed on about 3 years ago, and truck sat around barely used by anyone. When I picked it up I ran some Seafoam through the first two gas tanks as it was occasionally running rough and losing power. Since then truck has been running incredibly smooth, but in the last few days it is getting harder to start. If I pumped it two or three times it would start OK, but today I have had to pump it while cranking it to get it to start. ( the pumping may have nothing to do with it starting)
I am replacing the fuel filter in the next couple of days, as any accumulated junk that was in the tank or lines is now probably in the filter, but it seems that a badly clogged filter would also give me some problems running, and it runs really smooth once it starts. I get a pressure gauge, (I understand the rails have a pressure test port) what pressures should I expect at what moments?

Crank engine :
I am brand new to the F150 and trucks in general.
Ford 7.3L Power Stroke (1999-2003) :: Hard To Start / Smokes And Running Rough When Cold
I have a 01 7.3 crew cab dually and it's had cold start problems since i got it in 09.I have replaced everything i could think of including glow plugs gpr,harness and batteries. Any temp below 40 i have to plug it in . If i cycle it 3 or 4 times it will start but it smokes and runs ruff. My 00 7.3 excursion starts up down to about 10 degrees than i have to plug it in so i know dually is not right.
I have a afe intake,1.5 injectors, driven diesel rr, adrenilin pump,dp tune by gear head. Kinda at wits end don't mind plugging it in in dead of winter but now one night it's 30 next it's50 and i don't have to . Also have fully built trans by level 10 if it matters .I get battery light coming on every now and again. New alt about every year and a half.
Ford 6.0L Power Stroke Diesel :: Running Rough After Installed Trans Tune?
I towed my 32 ft/ 600lb travel trailer 115 miles into arkansas today. When I arrived at the campground, the engine was running rough and shaking the vehicle. I saw highs of 175 (trans temp) 1150 (EGT), 214 (ECT), and 224 (EOT).
I recently installed the canned trans tune from my new SCT X4.
I pulled codes (none), checked cylinder misfire count on scangauge 2 (none). In fact, all gauges on the SG2 were within spec. I popped the hood and let it idle for 15 mins. Temps all dropped down to what I usually see after normal driving (not towing).
The engine did start to calm down as it cooled, but still sounded a rough
Ford F-150 - 1997-2003 :: Trans Stuck In Drive And Does Not Downshift When Pull Up To A Stop Light
My truck is starting to shift strange. As it warms up and I'm in drive, it will shift between drive and 2nd by itself. When I pull up to a stop lite, it's like it's stuck in drive and doesn't downshift. Ultimately it dies. I've checked my fluid and its fine. Any ideas? Oh and my engine light is on. Can a parts store find the code for the issue I'm having?

Iv heard a few things about changing the valve body. I tow a trailer so was wondering on pros and cons of changing this. And also what brands are recommended.
View 5 RepliesFord F-150 - 1997-2003 :: 4R70W - Trans Has Hard Time Getting Into 1st Gear
The truck:
2000 4X2 F150
4.2l V6
280k miles/ some towing
The problem : The trans has a hard time getting into 1st gear. When you put it into gear you have to rev it to about 3k (when it's warm, 4k when cold) RPMs at which time you feel a definite engagement and it goes through the rest of the gears just fine. Once it's warm it will do stop and go traffic as long as you start it with the OD off.
The background : Orobably the stock motorcraft filter on there, and I don't think the oil has been changed in the life of the trans, but I do know that it's never been ran low on fluid. I took a gander at it and found a plug where a gear type speedo went on older models to be loose and leaking. tightened it up about two full turns. also noticed what looks to be a leak where the main case meets the output shaft housing. now I know neither of these are the cause of my headache but I do wonder if the second leak might be a sign.
The research : I've been looking for almost a week now for a solution. I've been all over TCCoA, Explorer Forum,10 pages of search here on FTE and various other Ford based websites and have come across a single thread with the same symptoms but the OP never came back with a solution.
The plan : A fluid/filter change (and flush) is definitely in the plans as well as inline filter for my own satisfaction. from what I've read the stock 1-2 accumulator is known to go bad on some of these and if I have the pan off might as well check anyways.
Ford 7.3L Power Stroke (1999-2003) :: Running But Losing All Power
Where I should start? My 7.3 is running but losing all power. Pumping the fuel pedle will get it started and it will run for a few then lose everything again. Should i just drop the tank and check the sending unit and intake and filters first then work my way up?

I bought a 1997 f150 with 160l miles on it. It is a 4x4 with the 5.4 v automatic. While I'm drive and in 4th and 5th gear, the tranny shakes the whole truck and then shifts hard! I check the fluid and it's still good and red but looks like there is to much. I'm planning on removing some and adding some lucus additive in it. What could cause this???

The bolt that holds the dipstick on the valve cover. i have tried for ever to get this thing off. soaked it , got a skinny wrench on the nut underneath but think it might be stripped (1/2 inch grinded out a little). going to try and get a set of skinny wrenches tomorrow , mine bent. tried vise grips on top of the bolt and put a box wrench on the nut , and gave it my all. The damn thing won't budge.
Also, any tips on the rest of the valve cover bolts. I had to remove some from inside the fender well but barely got to them. My question is not getting these out but getting them back in. And how the heck to you torque these things??? The bolt i mentioned above is creating problem, and I only have so much time
Ford 7.3L Power Stroke (1999-2003) :: 6 Speed Trans - Stuck In 6th Gear (Overdrive)
I have a 1999 F250 4-wheel drive with a 6-speed tranny. The tranny is several old but has only around 100k on a rebuild. Three times recently it has stuck in 6th gear (overdrive) and I had to get really rough with the stick to get to come out. Afterwards the stick felt "thick" for a while and eventually everything seems to go back to normal. Not for sure but it may have started after pulling a heavy load, around 16k, which is not unusual for the truck. Other than the times it stuck and shortly after, the tranny seems perfect.

I have a 1997 f150 lariat 4.6, at some point i started losing power, so of course I had my friend come by and check all the mechanics under neath the hood and besides needing caps and rotors all seemed well under there, so twice I've put it on a computer and it needs and o2 sensor, I've already checked my Cadillac coverter , and dropped and replaced my gas tank twice, I ended up having to replace a shock, it does run better when i put heat through it for a short time.
I've been checking my antifreeze and I am not losing none, I also did regular maintenance to it to figuring it was a fowled plug but still no good , so whats next ? coils ? I didn't replace my plug wires but I checked them all and they looked to be in good condition and I have a transmission filter kit to change that out I don't believe its been done ever ..
Ford F-150 - 1997-2003 :: Rough Running Only In The Morning
My 1997 f150 4.2L 2 wheel drive truck has been running rough only in the morning. In the last year I have changed the plugs, wires etc. As soon as I start the truck and attempt to drive, it is very hesitant, runs rough etc., but if I only give it a little gas and not push it - the truck will run fine. This will only last about 45 seconds and then it runs normal for the rest of the day. I do not have original FORD sparkplugs and someone told me that might be why. I spoke to a mechanic (did not work for Ford) and he told me it wouldn't make a difference.

2001 F150! It does this weird little surge, burping and farting away...but only in ambient heat. The engine never gets hot, it never over heats. What have we done? A full tuneup with new plugs and boots, oil change, new air filter, gas filter. It did it again...took it back in and had the fuel pressure checked, fuel injectors are fine...it can't be the fuel pump, it runs great unless it is hot weather. It has twice blown the P0171 system lean bank 1 code and has gone away after the tuneup and again after the new o2 sensor. It runs great, except in hot weather, starts surging and losing power...

Truck started just fine this morning, was driving for about 15 minutes and it started to lose power going up a gradual incline. I didn't even think of it really and so I just pushed the pedal in a bit and no increase in power, in fact it bogged down. I let up and went back to the gas and same thing. This was barely pressing the pedal down. I got to the top of the incline and started back down a bit and gained speed (dropped from 55-60 to 40 at the crest) up to 55, hit level ground and started to lose power again, and it felt for the life of me like the truck was fighting for every ounce of power it could get. Everytime I would step on it it would bog down again. I nursed it to an appointment I had, and when I got done with that I started back home. Same thing. It would accelerate from a stop up to 30 (I've always been a laid back accelerater) and when I would read 35-45 it would start to dog again. I got it back home.
2nd issue: On the way home I had to stop at a highway crossing on a slight inline. There the truck started to shudder a bit. and if I would just touch the gas pedal it would bog down. I played with it a bit and got it to rev a bit. put it in reverse got away from the intersection and let it idle a bit when It died. started right back up, no problem. would play with the accelerator and same thing. I finally got it to rev a bit and 2 footed it back home slipping from neutral to drive.

Sometimes the truck is hard to get started and to keep running, Once it warms up it will run fine. The next time it is started it will start fine but when you are going down the road if I try to accelerate it will start backfiring and not pick up any speed. I am getting a lean code on both banks. I have changed the IAC, the throttle position sensor and mass air flow sensor. 2002 F150 with 6 cyl

Ford F-150 - 1997-2003 :: Engine Running Rough During Idle And Driving
I am having a problem with my 1997 f150 4.2 v6. The engine is running rough at idle and while driving. It's running so rough that it vibrates the entire cab of the truck. I found water in the oil when I was trying to fix the problem. I have since had the heads redone and replaced all of the gaskets thinking this was the reason for the rough idling and rough driving. It wasn't; doing this fixed the water in the oil but still I have the rough running engine at idle and driving.
I have replaced the EGR valve, plugs and wires, pcv valve, replaced the coil pack, fuel filter and air filter (everything has been replaced with ford recommended parts because I have read that the engine I have doesn't like after market parts). While driving the engine vibrates and sound as if it's going in a cycle in a rhythmic sort of way (like a washing machine goes in a cycle), best way I can explain it. I have come to the end of what I think it is?
