Ford F-150 - 1997-2003 :: 2002 - Slight Vibration In Rear End When Cruising Down The Highway
Noticed my 2002 F150 had a very slight vibration in the seat / steering wheel when cruising down the highway at 60 MPH.. Very slight, but was not there 2 weeks ago.. It seem to get a little worst as the 2 weeks progressed. Got all 4 tires balanced and rotated... no luck...Took both rear wheels off-- no problems with tires -- checked bearing clearance-- pushed and twisted on driveshaft yolk to check pinion bearing... nothing found......... last resort was drop back end of driveshaft and check U-joint.. It was tight and dry. Put drive shaft in 12 ton press and pushed out the u-joint bearings. Very dry and joint pins were starting to spall....... I mention this because I had checked " clearance" and "slop" and had "no noise" before removal... Truck has 139K miles on original u-joints .......... Something to keep in mind. Eventually it would have worn to the point that it was obvious, but in the first stages of failure, you just get small symptoms.
View 7 RepliesFord Escape / Hybrid :: Starts Out In 1st Gear And With Little Feathering Of Throttle Shift Directly To 3rd
I am working to analyze my Granddaughters 2008 Escape FWD Auto 2.3 L issues with the Transmission. Vehicle has 142K miles with engine oil changes but no maintenance on the Transmission.
Engine was replaced about 9 months ago with a used 2.3 L with 52000 miles. Engine runs fine with no issues and NO Codes. BUT when driving the Escape I find it starts out in 1st gear and with a little feathering of the throttle will shift at 2600-3200 rpm directly to 3rd gear. (Based on known ratios and rpm vs MPH) Also no OD/ 4th gear. OTHER than the shifting issue it runs fine.Reverse works normally.
Summary: NO CODES from OBDII, NO OD lite ON or flashing, NO leaks, "wrench" light is ON solid after 1-2 miles driving, "wrench" light is OFF on restart but turns ON after 1-2 miles driving, Changed ATF - old fluid was slightly dark but looked and smelled OK - Drain plug magnet had slight coating of sludge - no dirt, metal or other solids. Transmission Shifting Lever properly selects Park - Reverse - Neutral - Drive with a quick/Normal change.
Ford 7.3L Power Stroke (1999-2003) :: Slight Hesitation In Throttle While Cruising / Truck Stalled Won't Fire
Last night I bought 2000 F250, 346k on it... Crew cab short bed 4x4 with ranch hand bumpers like I wanted .... Headed back home (Miami FL ~1100mi) and covered about 200 miles @70-75mph before i ran into few problems ....
First off, while cruising I noticed slight hesitation in the throttle, with loss of speed regardless of pedal pressure, noticeable on inclines. It would go away on downhill and get smooth response again and pick up speed. This went on for about 40 miles.
Then I noticed heater blower stop blowing hot and start blowing cold, without me changing any settings. At the same moment, I noticed temp gauge move up and I hit next exit offramp to check what's up. During right turn at the end of off ramp truck stalled. Pulled to the shoulder, and popped hood.
Noticed empty degass/overflow bottle. Carefully opened lid and water gushed up to the top. When all pressure slowly released, water pulled down and emptied the bottle. Both upper and lower radiator hoses are empty. Engine oil has no traces of water tho. There were no leaks under the truck. I then tried to fire up the truck to get me to the gas station 1/8th mile away.
No crank in Park. WTS comes on and goes off. Cranks in Neutral, RPMs come up some, oil pressure shoots up to normal running position, but won't fire. Tried a while then gave up as not to kill starter and batteries completely.
Fuel pump works 20 sec then shuts off. There is fuel in bowl. I covered 140 miles since last full fill up, so not fuel pickup issue I don't think.
Summary
Have crank
Have RPM
Have oil pressure
Have fuel
Have (had) batteries, now not so hot
It's cold out ....
Ford 7.3L Power Stroke (1999-2003) :: 2002 - Hesitating While Cruising Along At 35 MPH Roughly
I have a 2002 7.3 160k miles and recently it has been hesitating while cruising along at 35mph roughly. In park right off idle the engine does shake but if i give it a little more pedal the shake clears out. Not sure if that has anything to do with my issue but im just throwing it out there. Anyways cruising down the road the truck will hesitate almost like its not getting enough fuel the engine bogs then picks up then bogs and picks up but it i give it more pedal the truck gains speed and the issue stops and i can resume cruising at say 45 and not feel this hesitation at all.
On the toll road i never feel the hesitation cruising at 2k rpms. A problem that might of lead me to this issue was in the winter below 30 degrees i would drive the truck get to a stop light engine still cold or maybe warming up off the cold mark but when i go to take off from a light its like my fuel pedal doesn't work but the rpms will climb a little then the truck takes off and jerks really hard since i had the engine rev'd up. which made me think throttle sensor immediately or maybe the trans is having issues. since its warm out I don't have that issue now so i believe that it the trans. do you think maybe my hesitation now is also the trans? I never get a CEL. I did recently change the coolant temp sensor and now i am having this hesitation issue.
But I was told the ECM does not care about coolant temp on an auto truck so i dont see how that could affect my performance. Instead the autos monitor oil temp and the manual trucks monitor coolant temp correct? I had an issue like this with the truck years ago when i purchased it i was leaving the gas station on very cold maybe 10 degree day and the truck fell flat on its face and threw a bunch of codes but i let off the throttle and got back in it and it took off like nothing happened. So im not convinced the coolant temp sensor was defective from factory. But this old problem of not accelerating seems to be coming back to haunt me.... and i think its in a new form with the hesitation once in a while. I think i forgot to mention the hesitation isn't all the time!
Ford Transmission :: 2006 Expedition - Surging Very Slightly While Cruising Under Very Low Throttle
My 2006 expedition surges very slightly while cruising under very low throttle. Usually most noticeable at 60-65 mph with no headwind.
Took it in and had my mechanic check it out. He confirmed the slight surge and said it felt like the torque converter was locking and unlocking. No codes or pending codes were found related to the power train.
Abs light is on for a bad rear wheel speed sensor. Code for right rear. Checking the sensor showed 3 ohms for right, 5 ohms left ( left is less than a year old on a new wheel bearing.)
Initial thought was the bad sensor is giving bad input confusing the pcm/tcm. But the condition remains with the sensor unplugged.
Driving down the road watching the tach, it does appear that the converter is not staying locked. Condition goes away with more throttle. Motor runs smoothly otherwise with no indications of misfire. Plugs have 50k miles on them, as does the transmission fluid. Fluid is red and smells fine. Never gotten hotter than 210 by the gauge in the pressure port.
Why would it lock/unlock at very low throttle, but lock tight with more throttle? Tps flaking out? Throttle body motor getting twitchy? Can I pull my popup to the hills this weekend?
Ford F-150 - 1997-2003 :: Surging When Only At A Very Min Throttle
I have been fighting this surging issue for a while. I noticed when it starts to surge i could turn off the a/c and it would quit. It only surges when i am only at a very min throttle. Does this make sense? What can I do to fix it?

Ford F-150 - 1997-2003 :: Clunks Around At Low Throttle Especially Around 50 - 55 MPH
I am having a strange issue with the transmission in my 02 F150 with the 5.4, but it only happens when it`s cold outside and the truck is warm, typically after shutting off the truck and starting it back up (like if I stop at the store for something).
Basically, it clunks around at low throttle, especially around 50-55 MPH. Sometimes, it will act strange as I roll to a start, but typically it`s fine up until there. If I hit the gas it shifts just fine, but it acts up at constant speed/throttle.
I am hoping that its a sensor or something that's confused vs. needing a rebuild or new torque converter.
Ford F-150 - 1997-2003 :: Throttle Body Cleaning
I need to clean my throttle body on my '97 F-150 and it has a label saying not to clean directly. Is it still safe to use TB cleaner and to go ahead and clean it? It needs done but how would I go about it.

I have a 1997 f150 with the 4.6l triton that just started to make a squealing noise. I have replaced a couple of pulleys that were bad but that did not get rid of the problem. It only makes the noise when I give it some gas and it is coming from around the fan clutch area.

The Throttle Body on my 2001, 4.6 L is making a strange whirring noise, when you puy your hand on the intake pipe, you can feel a slight vibration. The Truck idles and runs okay, with no codes. Giving it a little gas and the noise goes away. The last thing I did was clean the IAC with Gum Out Carb cleaner, the second or third time I've done this over many years, with no problems. I'm a little perplexed at the cause.
View 6 RepliesFord F-150 - 1997-2003 :: 2001 - Miss At Low RPM - Light Throttle
My 01 Super Crew 5.4l is missing at light throttle. Cruise control on flat hwy, no miss, slight incline, starts missing. Put my foot into it and either it stops missing or it covers it up where I don't notice it. No codes set at this point. It's got about 135k on it and for all I know it may have had the original plugs in it so I figured I'd change them. Changed the plugs, still misses. Shortly a code set, something about the EGR sensor (it's got another name but I forget what it is at 1:30am). I found I had broken a hose while changing plugs, fixed it, no more code, still misses.
When I sent my GF up to get the non-existent codes checked the parts guy sold her some Lucas fuel system cleaner. I'm figuring a COP going out but the cleaner pretty much completely fixed the miss, till that tank of gas was gone. Few tanks later and it's back again as bad as ever. I bought some seafoam as I've had good luck with that in the past. It almost completely fixes the miss but I get a rare 'bump'. What do I need to look at next? Can it be the fuel filter? I'd think no because I'd figure it'd be even worse at greater throttle opening. Injector? How do I check them?
Ford F-150 - 1997-2003 :: Hesitation As The Throttle Is Pressed During Driving
2003 Ford F150 XLT - Truck hesitates (or bucks) as the throttle is pressed. Not from a stop though. It starts / runs fine, but no matter how how fast, what gear, hot or cold, it feels like the fuel cuts out for 1/2 second. Also it is not a specific point in the throttle motion. It does it when it is halfway, 3/4 or fully depressed, but is not consistent. It does happen more frequently now than two weeks ago. I am not getting a check engine light.

Ford F-150 - 1997-2003 :: Started As EGR / Throttle Body Clean
I'm usually over in the EX forum but today was working on my brothers 1998 F150 - V8 4.6L. Had the EGR code P0401 and due to FTE I found the problem took the throttle body off and found it was definitely plugged. One of the bolts was really loose and came off way to easily. Didn't realize until cleaning why... Now I drilled 8 studs out of my aluminum EX heads but this one has me pondering how I'm going to clamp this thing down and center a bit..
1st pic - ports WOW - guessing this was the problem ...
2nd pic - bigger issue ...
3rd pic - the ports cleaned up ...
Ford F-150 - 1997-2003 :: Switches To Defrost When Step On Throttle
When I have my a/c on, every time I step on the throttle it changes where the air comes out of the vents . Under normal power the air blows out the front vents, step on the throttle and it switches to defrost , let back off and it goes back to normal.?????

For example. If you are going 30 mph the engine surges. It surges when the throttle is in the same tps location.

View 1 RepliesFord F-150 - 1997-2003 :: Knocking And Vibrating - Gas / Throttle Pedal Noise
2001 F-150 4.2L automatic, 189k mikes. Gas pedal would do weird knocking/vibrating. It would do it at idle & under acceleration. Gas pedal would knock & sometimes slightly move or kick back at you. Felt like someone was lightly hitting it with a small hammer. Well there is not much to the gas pedal assembly; pedal, throttle cable & mounting bolts/plate. Looking under hood, a bracket from drivers side of motor was pushing back against firewall, which was pushing into gas pedal mounting bolts. I grabbed the bracket & it came off motor. Nothing else attached to bracket. Looks like it rusted off and was pinned between motor & firewall. Well, this fixed the gas pedal problems. But now i wonder what the bracket is & whats it suppose to hold??
