Ford F-150 - 1997-2003 :: Stalls At Idle - No Codes
My buds 2003 4.6 liter stalls every time he takes his foot off the pedal. Runs fine otherwise, no roughness or anything, you just have to keep your foot on the thing to keep it from dying out.
We checked for codes and found none. I checked vacuum connections and they looked OK.
Is there an easy way to test the IAC or should we just throw a new one in and cross our fingers? If we do change it out, does the truck need to be driven around a bit for the computer to re-learn anything?
Ford F-150 - 1997-2003 :: Engine Stalls When Reading Codes
I've got a 1997 F250 with a transmission problem that I've been trying to diagnose. The problem is I can't grab any codes from the truck. I took her to the transmission shop and they described to me the same problem I was having. Whenever I try reading codes with the engine off it fails, when I try reading codes with the engine on it stalls the engine. The transmission shop referred me to another shop that might be able to figure my problem out, but I'd like to leave that as a last resort. I've checked all fuses and relays and I have a new engine computer on order right now. However, I'd like to know if there are any other possibilities.

I've been having this problem since I've gotten the truck about year ago. it has very high long-term fuel trims and it seems no matter what I do I cannot get them to go down my fuel trims at idle are 39 Bank1 and 33 bank2 they go down to around 12>7 while driving what could this mean. And even weirder occasionally I get Bank 1 or bank 2 too lean codes at idle when cold starting???? 1997 Ford F150 4.6 ......

1997 F150 4x4 210,000 4.6L Windsor 5 Speed. Engine totally rebuilt 15k ago (besides for timing chains and tensioners). No codes thrown.
This morning when i started my truck, it made a knocking sound (almost like metal slapping) that seemed to be coming from the bottom end of the engine. At first I thought it was a spun bearing, but then the sound went away after a minute or 2. I have Google'd the problem, and have found a few diagnoses such as: oil draining back from the filter (or something like that), or an exhaust manifold leak that stops when the metal warms up and expands, or even the starter motor not being aligned right and not disengaging properly...
This is the first time this truck has ever done this. I changed the oil and filter about 1000 miles ago with 10w-30 oil and I believe a WIX filter. Also, this is the first time using the WIX filter
The weather this morning was around 51*F, so not too cold (to me).
Also, a few weeks ago when I changed my oil, I noticed milky white stuff only on the bottom of the oil cap, and in the feed neck. The rest of my oil looked like perfect used oil. After I noticed the milky stuff, about 2-3 times a week I would clean the stuff out of the neck and off of the cap. Just recently, there hasn't been as much milky fluid. My coolant level has not changed since I marked it during the oil change. A few buddies have said it might be condensation, but it's never been like this before.
I guess my question is, is this something that could put my truck out of service if left untreated? I'm assuming it's not a spun bearing because the noise goes away, but is there a possibility coolant could be leaking into the case but stay the same level in the reservoir?
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.

I have a 2000 f150 4wd 4.6. It wouldn't start this morning. A few years ago I had to change the inertia switch so my first move was to bypass that, which didn't work.
After that I gave it a shot of ether to see if it would hiccup and tell me if I had spark or not. It started up, ran rough while the air cleaner was off, then cleared up and ran fine, and is now starting/running fine again.
The problem is that I have to take the truck on a trip Saturday, and I can't figure out what the problem was if the truck is starting. What it could have been? No check engine light or anything either.
Ford 7.3L Power Stroke (1999-2003) :: 2002 - Blue Smoke On Cold Morning Start Ups
Got a 2002 7.3 F-350 with 300,000 miles and for the last couple of years I've been getting blue smoke on cold morning start ups and its been gradually getting worse, it clears up after about 30 seconds and all is normal,No loss of performance, Oil consumption is minor, however I hate a vehicle that blue smokes, I'm guessing my issue is valve seals are worn, I was wondering if it is possible to replace the seals while the heads are on the engine? and was also wondering how much time it would take to fix? as i would have to have it professionally done. I know its hard to guess a time frame and everyone is different. Sounds like textbook valve seals to me but is there anything else I should check first?

2003 F150 5.4L Tow Package 140k miles... Had coils, all plugs/wires replaced two years ago due to vibe climbing hills. Now at startup in the morning for a minute or two during idle, the engine vibrates severely then subsides and runs fine rest of day. Doesn't do this every morning. Truck lives in FL. The issue is either temperature related or moisture related. Ford service has the truck presently and attempting to diagnose from an overnight stay. They already 'fixed' the problem last week by replacing #1 plug/wire and resetting the power control module (pcm) but two days later the problem came back. Tech said today that the plugs currently installed are Bosch (any issue with these plugs?)

Camry :: 2003 - Transmission Doesn't Shift Out Of Second Gear When Start Driving In Cold Morning
My camry has been great up until the last week. The weather has gotten extremely cold here and when I start driving in the morning or from any cold starts the transmission doesn't shift out of second gear. After I drive it a mile or so and slow almost to a stop it will shift normally until I park it.
It has 125000 miles on it and I hope this isn't a serious problem because it is a great car and has been well taken care of. Looks brand new on the inside and out and I've never had any problems until now.
Ford F-150 - 1997-2003 :: 1999 - Stalls / Won't Start When Hot
1999 F150. The truck is a 4X4 supercab, with the 4.6 motor, 141,000 mi. During cold weather it runs great, but as soon as the temp gets into the upper 70's or higher I have a recurring problem. The truck starts right up and runs well, but when it is shut off it will not restart until it has sat for over an hour. It has also stalled at speed on the freeway when the outside temp was in the upper 90's to low 100's.
So far it has always restarted after sitting for awhile. I took it to the dealer and they kept it for 3 days, but could not duplicate the problem and found no codes in the computer. I replaced both coils, but it is still not starting after shut down when hot. My next thought is to change the PCM, but that is a big chunk of change to be guessing about.
Ford F-150 - 1997-2003 :: 1999 - Stalls At Idle - Won't Start?
My dad has passed his 99 f 150 with 130,000 miles to me. It is a 2 wheel drive, extended cab automatic equipped with the 4.6. Recently, the blend door failed and as a temporary measure I installed a ball valve in the heater core supply hose. The ac now blows ice cold.
On two occasions since the installation of the ball valve, the truck has stalled at idle when in park and would not start, although it turned over fine, until 30 to 45 minutes elapsed. On both occasions it was a hot day. The check engine light is not on and no codes are stored.
Ford F-150 - 1997-2003 :: 2001 - Truck Stalls Under Load
I have 2001 F-150 with 4.6L. Truck runs fine until under load and runs fine until I slow down to a stop sign. Once truck sits for a few moments it fires up again and will run for a short while then will do it again. Each time i let it sit for a few minutes, it will start again.
I pull a small travel trailer and seems to happen more frequently when pulling or climbing hill, but not under full power, just when slowing down. Could this be cause of catalytic converters? MAF sensor, or fuel starving.
Check engine light is on, will codes identify if it is a plugged cat?
Ford F-150 - 1997-2003 :: Stalls / Stutters - Cranks But Won't Start
So I leave town Friday with the wife's car for a golf tournament that is 4 hours away. I left her with my 2001 F150 Supercrew Lariat 4x4 5.4L. She calls as I am starting my practice round on Friday stating that the truck had died on her in the local Dillons parking lot. She had driven to the east side of Wichita, then drove all the way back to the west side before swinging into Dillons to get some chinese food for lunch. When she gets in the truck to leave, she starts it and it runs rough.
She gave it gas and it ran fine for a few seconds, she put it in drive, and then it started running rough again. She stopped the truck in the parking stall ahead of her, turned it off, and restarted it. Same thing...runs rough. She tried giving it gas, but it would not go above 1500 rpm. Then it just died on her. She then tried cranking it, but it would not turn over. She let it sit overnight and got a ride from a friend (it was 102 degrees out), went back the next morning to try again. Same thing, just cranks. So I get back last night and go up with my scanner. No codes, no SES/CEL.
So, I am now thinking it is the fuel pump. I crawled underneath the truck and had her turn the key so I could see if I can hear the fuel pump. Nothing. I went ahead and disconnected the battery to let it sit overnight.
I am about to head up there and see what I can do. So far, here is my list of things I need to check:
1. Fuel pump relay #301
2. Fuel pump fuse #18
3. Check for the theft light
4. Check "inertia switch" on the passenger side kick panel
5. OPEN gas cap and listen for the fuel pump (had never heard of that one)
6. Hit the gas tank a few times with a rubber mallet to "jar" the fuel pump (again, never heard of that one).
My question to all of you is: Am I missing anything else? Alos, with it running perfect, then running rough and suddenly dying, would is necessarily be the fuel pump? I had read something about a "Fuel Pump Module" located near the spare tire. Is that something I should check into with it running rough (well, not running at all now) like this?
Ford F-150 - 1997-2003 :: Truck Stalls Out In Gear But Not In Park
I had what I was told was the breather (on the drivers side valve cover) snap off. I was able to place a piece of tubing In it and reconnect it. I had to change the #7 cylinder spark plug wire. Got a misfire code and found the wire was loose and corroded. Replaced wire and PVC valve.
My problem is, it seems not to be idling as fast as it was before this happened. The truck stalls out now in gear but not in park. 1997 F150 4.6 ....
Ford F-150 - 1997-2003 :: Stalls Out At Idle After Manifold Replacement

View 4 RepliesFord F-150 - 1997-2003 :: Codes Came On Again - MAF?
1997 f 150 4x4 5.4 right now has a 145k miles.
About a year and half ago (120kmiles) the check engine light came on, checked the codes; 1 left bank to lean. 2 right bank to lean. Cleared the codes drove for about 3 weeks and the light came back on same codes, cleared the codes, drove for about 3 weeks and the light came back on, this continued with shorter times between the light coming on. Did this until sept 2012 took it in and Ford replaced the MAF, all good until today Jan.8, 2014. The light came on today I checked the codes 1 left bank to lean. 2 right bank to lean, cleared the codes today, the light staying off for right now. My best guess is that the MAF is again bad, my question is; how long does a MAF last, why would it fail in just over a year? What can I do to make the the MAF last longer.
Ford F-150 - 1997-2003 :: Idle Down To The Point Where It Almost Stalls When Stop Or Park
2001 f150 supercrew 5.4 triton... Recently did a tune up plugs,coil packs,filters,belt the whole 9 yards. The truck starts fine accelerates great and cruises down the road great without missing a beat.
But every now and then when you stop at a light or park it begins to idle down to the point where it almost stalls. When it does this i usually stab the throttle and it revs right up without missing a beat and idles fine for a a while then same thing all over again.
Could this be the idle air control? Seems like something simple due to the fact it runs down the road and accelerates like a big dog.
Ford F-150 - 1997-2003 :: 1998 V6 - Loping At Idle / Almost Stalls While In Gear
I have a 98 F150, 4.2 V-6, 183,000 miles.. Lately, she's been loping at idle. Especially while in gear... almost stalls. Once revved up, everything seems normal. Still goes up hills fine if I get on the gas. The light was on, and I got codes for lean condition on both banks.. (P0174, P0175).
I already cleaned all the sensors in front of the intake.
The MAF was real dirty, and the IAC was full of soot too.
They both cleaned up nicely, but it didn't work.
I borrowed a fuel pressure gauge yesterday, and it showed 12 psi with the "key on, engine off".
It showed 29-30 @ idle, and only went up to 35 when I revved it a little.
The guy at the store said the range is supposed to be "30-45 psi with the ignition on", but I'm not sure if that means engine running or not..?
Either way, it looks like the pressure is on the low side, so I'm going to change the fuel filter next (and hope for the best).
If the fuel filter doesn't fix it, what should I go after next? And, is there a way to test the fuel pressure regulator before buying a new one?
Ford F-150 - 1997-2003 :: CEL Came On / 5 Different Fault Codes
The check engine light came on in my truck and while I suspected it was a misfire (driving along it will misfire like crazy at certain RPM). What I cannot figure out is exactly which coil is causing the problem. I get these codes:
P0306 - Cylinder 6 misfire --> Easy enough, cylinder 6
P0356 - Ignition Coil F Primary/Secondary Circuit --> Which cylinder is this?
P0356 - Ignition Coil G Primary/Secondary Circuit --> Which cylinder is this?
Assuming that cylinder 1 is the front left (when facing the vehicle) am I right in that cylinder 6 is the 2nd from front on the right (when facing the vehicle)? Would Ignition Coil F also be on cylinder 6? and therefore ignition coil G be cylinder 7?
The other code I am getting are both the same:
P1740 - Powertrain
P1740 - Powertrain - Transmission System Problems
I suspect these 2 are related to one another, the odd piece is it drives fine other than the misfire. Hoping to cure the misfire so that it drives smoothly and I can then figure out the P1740 code.
