Ford F-150 - 1997-2003 :: 2001 - Shakes Violently At Consistent Speed?
2001 F150 4x4 harsh shaking. When driving at consistent speeds the truck begins to shutter and shake, begins as a light shake and becomes extremely harsh fast. This is not like a vibration that can be felt, but a really harsh shaking of the entire truck.
The truck continues to shake after taking foot off gas and braking. It will shake harshly even when braking and slowed down to 5mph, but instantly goes away once at a complete stop. Accelerate immediately after coming to a complete stop and it completely goes away and drives normal for a day.
Check Engine light has not come on. Tachometer stays consistent RPM. Shift into neutral does not stop shaking. Only coming to a complete stop ether in drive or neutral does the shaking stop. It happens driving at consistent speeds going 35mph & 65mph, etc. Any thoughts on what the issue could be?
Ford F-150 - 1997-2003 :: 2000 Truck Shudders When Accelerate From A Stop
I own a 2000 f150, 7700 with 199,000 miles, 5.4 eng. In drive with foot on brake, it idles at 600 rps, fairly smooth. When I accelerate from a stop the engine shudders. Ten months ago I had the plugs replaced, last week I bought 8 new coils and I installed them, no change. I removed the down stream o2 sensor from the exhaust, it was as clean as blued gun metal. Can these 2 sensors be cleaned or tested? The service engine lite is not on. List of things to check?

New here. I have a 2001 F150 which i love but lately has been an issue. I started it up a few weeks ago after it set over night. i threw it in to reverse and notice it hesitating while reversing and it has small trouble accelerating but does buck and jerk while trying to maintain speed. So I took it to my well trusted mechanic and he ran compression test and ran the highly prolific OTC scanner on it and nothing. I have changed my mass flow sensor and I dont show any misfires or any codes pending. I did replace a busted catalytic convertor a couple months back. Im running out of places to turn.

For over a year, the truck took 5-6 seconds of cranking to start, but always started. This morning it started, but shakes, coughs, and vibrates like hell. It revs up but still sounds like its hitting only on a few. replaced ciols many times over the years, but this sounds different.

2001 Ford Excursion 7.3 will run barely for about 20 sec. shudders, then dies. Bought new, driven 334K miles. Performed the usual fixes common to 7.3 issues over the years. All original injectors except for #7 which I replaced about 5 yrs ago. (I know should have replaced in sets but not in the budget at the time). Anyway had my wife turn the engine over after I had removed valve covers for inspection and observed a lot of smoke coming out of what appears to be at or around number 7 rocker arm valley? All rocker arm/pushrods look to be moving as they should beyond that I'm in over my head. Am I screwed or could it possibly just be a bad injector/injectors?

2012 6.7l CC SB SRW 4x4.
Truck has 9700 miles on it, bought it in December of 2012. Twice in the last week, when at about 60 mph on a flat road, maintaining speed with virtually no wind, there is a slow, gradual shudder from the rear wheels. Both times the truck has been on cruise control and if I add power, the truck does not accelerate and the shudder continues to increase. If pull power either by brake or canceling cruise, it stops and the truck performs as expected.
I have yet to have the time to reproduce this. My only hope is if the dealer is already aware. I plan on trying to reproduce it at some point with hopes of having something tangible for the dealer.
Ford F-150 - 1997-2003 :: Knocking After Get Up To Speed And Let Off The Gas A Bit
My 2000 F150 started knocking, it does this after I get up to speed and let off the gas a bit, it will know as I push on the gas again but if I push heavy on the gas it dose not knock, What could if be? By the way it is a hard knock not a pinging sound.

This started about a month ago. The truck surges at any speed as long as the gas pedal is at a static position. There are no codes. I have replaced the fuel filter air cleaner cleaned the maf and did a ton of reading on this issue. Is it the tps? The tps voltage does not fluctuate any when it surges. Maf,? Should be throwing a code right? Same as the egr valve. What am I missing?
View 8 RepliesPassat (B6) :: Shudders On Accelerating At Speed / Cylinder 1 Misfire
Our 2008 2.0T Variant with 70K miles runs fine, except while running fully warmed up on the highway. Then, at cruising speed, the engine shudders if you try anything more than gentle acceleration. If you push deliberately on the gas at about 1,500 rpm, the engine shudders, fails to accelerate, and the MIL flashes. This has been going on for a few months.
Wifey is about to go on a road trip and, although she's adjusted to this behavior, I don't wanted her stranded somewhere. The engine is throwing code P0301 (got it read at AutoZone), Cylinder 1 Misfire.
I'm wondering why it only misfires under these conditions, and not, say, while accelerating off the line or while idling.
Any tips? I've already put a bottle of Techron through the tank. Car has had all recall/service bulletin work done, which as I remember included a coil pack recall a few years ago.
I wonder if getting the car into the stealership before her trip is a "must." (I don't have my own scanning tool in order to sequentially troubleshoot coil packs. I can at least check plug wiring.

1999 F150 has a tremble or vibration between 27 and 40 MPH it does it in any gear but only between these speeds. I thought to begin with it might be a slight misfire, but seems like if that was the cause it would happen at any speed...

View 1 RepliesFord F-150 - 1997-2003 :: IAC Over Speed Error Code P1506
About 3 days ago I noticed my engine RPM was around 250 higher than usual. Usually my truck idles around 550-600 rpm (I know this is low). Anyway, yesterday it threw the P1506 "IAC over Speed Error" Code. It is idling very rough, shifting weird, but does crank up fine.
My truck is now at 93,000 miles and I just cleaned the IAC at 87,000 miles due to the common no start condition. I guess I am going to get a new IAC now since another code came up.
Well, my question is it came up with two other codes also:
P0171 - System too Lean, Bank No. 1
P0174 - System too Lean, Bank No. 2
Do you think the P1506 (IAC Code) made the O2 Sensor codes show up or is it really the O2 Sensors? I just changed my two upstream O2 Sensors around 90,000 miles. Should I get a new IAC or try to clean it again?
Ford - Taurus :: 2001 Shudders When Accelerating Uphill
I have a 2001 Ford Taurus with 103,000 miles. It shudders when I accelerate; sometimes one, two or three shakes. This usually occurs around 35-40 mph while I am going uphill (never while going downhill). I always use overdrive, but I tried it in drive and also felt it then.

I recently got a 2002 f150 5.4. The fan speed works on 1 & 2, and 4. It does blow on level 3, but it seems to blow at the same cfm as level 2. I'm thinking this can't be right. But, if it was a simple resistor issue, it wouldn't run at all on level 3, right? So, where I should look first.

View 1 RepliesFord F-150 - 1997-2003 :: 1999 - IAC Over Speed Error Code P1506
1999 F150 4.2L 125K miles.... My problems started about a month ago. I had a P1506 error. The engine was running fine but received the error code. I replaced the IAC and the air filter. Engine still running fine. A week later I received a code for the Intake Air Temp Sensor (don't remember the code). The engine still running great. I bought a new Air Temp Sensor and noticed the wires from the Air Temp Sensor were rubbing against the belt and had been severed. I made a mistake when replacing the air filter of not checking the wires (confession is good right).
The engine also constantly ran a fast idle 2000 to 2500 at this time. I repaired the wires. The engine light went off and idle now starts great and smooth but when heats up will will go to 2000-2500. I then decided to replace the Air Temp Sensor hoping to fix idle problem. Engine still idle fast when warm. However, when I come to a stop and put in neutral the engine will take a minute but go down to normal idle after sitting. Engine light stayed off for a week. Now engine light back on with original code P1506. Idle is still not working correctly.
I feel like I made it worse than it was originally and not sure what to try next.
Ford F-150 - 1997-2003 :: Engine Just Died While Pulling A Boat At Highway Speed
I have a '97 4.6L 4x4. I've had a few issues recently and am at wits end.
Symptoms: while pulling a boat at highway speed, the engine engine just died. After waiting about 20 minutes for a buddy to show up with a tow rope, it started up and ran fine...until I got home (10 miles). I parked and after approx 5 minutes of idling it died again. No CEL, and found no codes when scanned. 15 minutes pass, it fires up and works fine.
The next day, I hook the boat up again, dive to the lake, go fishing, drive home. Everything was fine. I unhook the boat and drive to work. Half way there my voltage gauge starts falling and 5 miles later all of my gauges end electric stuff dies. I drive two more miles to work and strange beep starts coming from under the dash on the passenger side (I think). After my 12 hour shift it starts and I start my 10 mile commute. Half way through I lose electrical power again but make it home. Now it doesn't have the juice to turn over.
Are these problems related, and what are the possible causes and cures? On an unrelated note, what's the easiest way to replace a rear leaf spring shackle?
Ford F-150 - 1997-2003 :: Sluggish Picking Up To 100 KPH When Began To Accelerate Up To Highway Speed
I have a 2001, 2wd, XLT, Super Crew with 4.6L and 180000Kms. I am the 2nd owner and have owned it for roughly 6 years. Since owning it I have towed the following: a 1500 Boat, 1000lb full utility trailer, a 2700lb boat, and most recently (Last summer) a 3500lb dry weight/4000lb full 22 foot camper trailer. None of these items ever caused me any problems til mis summer with the camper.
I have always got check engine lights for the stupid coil packs. It seems like I would replace one and a different one would go. I was camping one weekend a short hour distance from my home when I pulled onto the main highway and began to accelerate up to highway speed but it was feeling sluggish picking up to 100kph. When I merged onto the highway it was not a flat piece of ground and was a small grade of a hill, but nothing big. Before getting to the top I started to hear a strange noise, almost like a rattling, and the check engine light started to flash. After breaching the hill, it picked up speed, the light went out, and everything seemed fine.
This happened twice last summer with no other problems. At the end of the summer I once again had a check engine come on...I had blown out a plug, had it fixed and replaced 2 more COPs but still had codes showing for CC, M, F, O, OH, C, E and EV. My reader also said Freeze Frame, and MIL on. I had the truck in in Nov/Dec for an emissions test and it was given a conditional pass due to codes reading but no Check Engine light at this time.
I want to keep this truck...I will be towing the camper again, buit I'm considering getting a different truck. As it is I know I already have to have air bags installed in the rear to level out the load when towing. Hopefully that will cut back on some of the acceleration drag. At present time I have a check engine on...I'll check it again and post what its reading but most likely the same stuff.
