Ford F-150 - 1997-2003 :: Pinging Badly When Towing

My wife's brother has a '97 F150 w/4.6L/automatic trans/4x4-OFF ROAD package. It's a standard cab, short bed (fleetside) truck.

It has 126k miles and he is METICULOUS about routine/periodic maintenance. He's owned it since new, has changed the plugs twice.

Is this a common issue with the '97 4.6L? He says he has tried using premium fuel to determine if it makes a difference. He said it worked but it still pings, just not as bad.

Ford F-150 - 1997-2003 :: 1998 - Slow Towing - Specific Trailer?

I bought my truck a couple months back for my custom furniture business. It's a '98 F-150, XLT, 5.4, supercab, 4x4, 3.73, 4R70W, 176k miles, with tow package. Today I picked up a single axle 6x12 trailer enclosed with metal mesh, weighs about 2000 lb. This was my first time towing with this truck and I figured it would run a little slow but this was ridiculous.

Highest speed I could get to was 64 going slightly downhill with OD locked off. Most of the smaller inclines and flat areas were max 55, then the worst was a two mile 7% incline at 35 mph. That last one just wouldn't downshift. This was all between 5000 and 6000 elevation in the Rockies. It's a little embarrassing getting passed by loaded semis

Am I doing anything wrong? Could it just be this specific trailer has issues?

Ford F-150 - 1997-2003 :: Misfire On Cylinder 3 (P0303) But Only During Towing With Ethanol

I drive a Supercrew F150 5.4L XLT 02 since 9 years, I put a Fuelflex module since 8 years, since some months I Misfire on cylinder #3 (P0303) but only during towing with Ethanol (over 2000/2500 rpm), when I drive on gas all is fine, I changed Flexfuel modul, plugs, coils, header gasket, without any positive results, it's very curious to have the problem only with ethanol (E85), I can drive very hard and at high speed with just the truck, but with a trailer as soon as I ask more power i lose one cylinder, with misfire...but like I said only on ethanol? I know engine needs more ethanol than gas, so I go check fuel pressure and maybe try to change fuel injector...

Ford 7.3L Power Stroke (1999-2003) :: More Black Smoke When Towing?

Normally I run around sea level at home but Iam on road trip in Wyoming at over 5000' elevation I am noticing alot more black smoke when towing. I run a DP tuner with 40 and 60hp tow mode. I also notice alot more black smoke in 60HP Econo Mode when not towing? Would this be typical due to the higher elevation?

Ford 7.3L Power Stroke (1999-2003) :: 2000 - Vibration While Towing At Low Speeds

I have a 2000 with a six speed and through the first 2 gears while giving it only a little throttle, worse on hills and worse while towing I have a pretty decent vibration. Once you get to 3rd and up its fine. I have read about axle wrap and due to the fact my springs are pretty wore out I think this is a big part of it. Any other things to look at other than new springs? The u joints all look and feel fine so I haven't touched them.

Ford 7.3L Power Stroke (1999-2003) :: Some Gauge Reads Towing Light

Towed 3 axle trailer loaded with a 73 VW bug, two implement bars, plows and a small boat. I would guess total weight at 7,000 max. The ambient temp 97 degrees and very humid. I have a 2000 dually.

The following are from the ScangaugeII
TFT trans temp 175 max
EOT end oil temp 205 max
SLP trans slip 0.20 max and 0.0 in high gear

From glow shift
Water temp 196

The one I am worried about is the trans slip, from a stop taking off always went high 0.15 to 0.20 and then drop quickly. Once the TC locked 0.0 down the road. Also, when I reverse with no load on dirt I have seen 0.20 on the trans slip. I have Forscan but have not logged any temps yet....

Ford 7.3L Power Stroke (1999-2003) :: Check Engine Light While Towing

2001 F350 290,000 no mods other than 6637, 2WD

Towed our new to us RV home last, only 15 miles from the dealer and yes its a big 5th for my truck at 12,000lbs. Anyhow, about 2 mins from home as I'm pulling off the freeway I got a SES light come up, then it disappeared. I checked codes this morning using forscan and nothing shows to indicate what it may be.

I was wondering if the transmission is getting hot if it throws an SES? It was only a short trip, but I have no real idea of the condition of the trans as the truck is new to us too - fluid looks and smells good.

Only new code is an ABS one c1229, c1233, C1234. I had 2 of them before - think the 1229 is the new one.

Ford 7.3L Power Stroke (1999-2003) :: Shuddering Low Gear Acceleration When Towing Heavy?

2002 F350 7.3, MANUAL transmission ZF6.

Bought this truck used for hauling an excavator, and after fixing damn-near everything engine/turbo/and-cooling-system-related ---- it's finally seeing some use.

Just recently started hauling 12,000lb payloads. When I accelerate hard in Low gear, and then shift into 1st and accelerate hard again, I feel the whole truck shuddering. It's like a shimmy-shaking vibration all through the vehicle.

It doesn't happen in higher gears, only when the following conditions are met...
1) Starting from a dead stop
2) 12,000lb payload (heavy)
3) Accelerating hard (Low, First gear)

I would also like to add that I experienced this shuddering vibration very intensely when I put the transfer case in 4wd LOW (front manual hubs left unlocked) and towed 14,000lb up a steep hill in 1st, 2nd, and then 3rd transmission gears.

^^^ By leaving front hubs unlocked and transfer case in 4wd LOW, I was effectively lowering my final drive ratio even more for extra pulling power in 2wd hill-climbing. I don't do this often, only when absolutely necessary. ^^^

I must also add that I do have slightly taller rims/tires than OEM ford WITH the original ford gearing (3.73) so I'm more like 3.51 final drive ratio.

Ford 7.3L Power Stroke (1999-2003) :: 2001 F250 - Black Smoke When Towing Uphill

I have always seen other trucks blow black smoke with towing up a hill but mine for the most part has not. I pulled my 5er to CO this summer and notice my truck starting to blow black smoke. I consider myself a very conservative driver. I always stay around 65 MPH while towing and never push my truck up the hills. I always try to keep the RPM around 2000 and let the MPH fall where they may until I reach the summit. With the black smoke I'm starting to see what is my truck trying to tell me? It's not bad but would like to fix now before it becomes something more.

Ford 7.3L Power Stroke (1999-2003) :: 2001 F350 - No Power Especially While Towing

I just bought a 2001 F350 diesel with 120k miles on it a couple weeks ago. Friday I headed out to Oregon with my 16 foot enclosed trailer filled with jet skis (about 4-5k pounds) for a competition. A few minutes after being on the freeway I noticed the truck did not have good power. About 30 min later while climbing a steep grade the truck almost went dead.

I started at 60mph and by the time I got to the top i was at 15mph with the throttle pinned. the motor sounded funny and shook the truck more then normal. After wards on the down side of the grade the truck started to act normal. I took it to my buddies house and switched trucks because I didn't trust if for the 13 hour drive.

Today I talked to a mechanic at the dealership and he said that it sounded like injector o-rings to him. I went home, pulled the valve covers and started the motor to see if anything is leaking. steam was coming from the valve area and the down spouts on the injectors was flowing oil. The thing that looked especially abnormal was one of the injectors looked like fuel was dribbling from it. I don't know if that is a problem or not. I couldn't tell if it was fuel or oil but no other injectors had fluid coming out near the wire connections.

Ford 7.3L Power Stroke (1999-2003) :: 2000 - Power Loss While Towing Up Hills?

I pulled with my 2000 F250 7.3 for the first time yesterday pulling a 12,500 5th wheel and then again today with an 18 ft ski boat weighting around 3500 for both the trailer and boat. I had this same issue pulling both.

Today when pulling the boat/trailer i was behind a slow moving truck and when we hit a hill with a passing lane i merged over and wanted to start passing him. We started off at around 45 mph up the hill and as I started pushing the pedal I wasn't gaining any speed and my rpm's didn't even get over 1500. It felt like a stall and continued that at around 45-50 mph up the hill (about a 65 degree slope). When I'm not towing the truck runs great, plenty of power and averaging around 16 1/2 mpg.

Only mods i have is a 6647 Napa filter, muffler delete and it's running the same 4 position TS tuner from the original owner. During normal operation I run it at the 75hp gain and when towing i use the 50hp gain.

In both instances i could see black smoke coming from exhaust when pushing the pedal but my rpm's wouldn't go up and truck maintained the slow speed going up the hill. Once at the top it drove normal and picked up speed without any problems.

Ford 7.3L Power Stroke (1999-2003) :: High Pitched Squealing / Scraping Sound - Loss Of Power Towing Uphill

Towing a 5th wheel at about 10,000 lbs total. Towards the end of out 9 hour trip home and going upgrade the truck begins to loos power and the engine starts making some bad sounds. Although its hard to hear it starts about 45 seconds in and continues later when going uphill. the truck also made a very high pitched squealing/scraping sound (not a belt) like it may have been coming from the turbo. Oil temp was about 220, trans temp at 170 at the time of the event.

Truck has 216k, stock, upgraded trans cooler, original fuel pump.

Ford 6.7L Power Stroke Diesel :: 2012 - 3.31 Gearing Is Appropriate For Hauling?

I'm about to pull the trigger on a 2012 S.D. 6.7L 4x4 XLT Supercab Longbox seems all I can find is rigs with 3.31 gearing....I really want the 3.55 gears. Dealer is telling me the combination of the 6.7L with the new Auto Transmission is more than adequate for hauling. I will be hauling an Eagle Camp 950 Truck Camper along with a 10 foot toy hauler trailer....I'm not a freeway runner mainly secondary roads and mountainous terrain. I'm used to 3.73 gears and before than 4.10 gears.

Ford Super Duty (1999-2016) :: 5.4L - Hold Up For Towing?

How does the 5.4 hold up for towing? Which trans works the best with this motor? I have a 5th wheel car trailer that I pull with a 36 hp tractor and loader on it sometimes. Would the 5.4 be to small or should I just stick with my powerstroke?

I was think of updating my old pickup with a 99 f250 cc 4x4 with either a 5.4 or powerstroke and either a auto trans or 6 spd manual What are your thoughts?
