Ford F-150 (2004-2008) :: 2006 - Truck Is Bucking And Not Right Under Acceleration
I need to change my plugs in my 06 5.4 122,000 miles truck is bucking and not right under acceleration but its my only transportation to work and I am afraid of breaking a plug and then having no clue what to do after that. Need input on making the plugs come out easier ...
View 6 RepliesPassat (B5) :: Vibration Under Hard Acceleration When Downshifted
I bought a B5.5 wagon with 145kmi on it last week. It's a 1.8t with a tiptronic transmission.
Last night, when I stepped on the accelerator for the first time when it downshifted I got a nasty vibration until I let off. When just cruising or accelerating at a normal speed there is no vibration at all. It doesn't matter if you're doing 20 mph or 60mph, it's the same vibration when you accelerate hard.
I'm thinking maybe a motor mount or something?
Ford F-150 (2004-2008) :: 2006 Truck Starts To Skip And Shudder Under Acceleration At Around 40 - 45 MPH
I just bought a 2006 F150 with the 5.4 triton motor. Under acceleration at around 40-45, the vehicle starts to skip and shudder.
Based on what I read online and the fact that I pulled a code for a #1 cyl misfire, I assumed that i just need to change the plugs, and I am trying to scheduule that now.
I just read another post about the TC not locking up due to needing the filter and fluid changed and a way to fix that would be to take OD off and see if it still does it.
When I drive with the od off, it does not do it but i am now confused since i got the one code for a misfire.
Ford F-150 (2004-2008) :: Rumble / Shudder In Truck On Initial Acceleration
Just rejoined this Ford gang after years absence. Used to own "The Muny Pit", a '79 F-150 4WD monster with a '69 429... constantly breaking something. Anyway, where to look on my '08 F-150 XLT 4WD with a 5.4, 83,000 miles. Searched the search bar for my title and found a post on an '00 Expedition describing similar issue than mine... for about 6 months now when I accelerate either from stop or a crawl; forward or reverse; more so when turning, but does do it wheels straight.
Upon initial acceleration I have this horrendous rumble / shudder in the truck, like the grinding metal bearing sound/feeling felt when the pinion bearing went out on my '79 (only felt it seconds before the 9" rear pumpkin exploded). Once rolling it stops. I have checked all wheel bearings.. I have check all the suspension joints... everything looks fine, no obvious issues. The only suspension mod I've done is a 1.5" leveling kit when brand new. On the Expedition two replys suggested changing the transmission/transfer case fluids claiming it cured their vehicles.
Ford F-150 (2004-2008) :: Misses Under Hard Acceleration - Spark Plugs?
I've recently had a small issue with my truck missing under hard load. If you're going around 40 MPH and push it down like merging it will kick back and forth and sputter and then start hitting fine again after a few seconds and move on. Possibly bad sparkplugs and/or wires?

I have an 04 F150 (4.6, auto, 4x4, SCrew) with 300,000 miles. Any success modifying existing 4X4 IWE actuators so they are always locked in?
My last set of actuators didn't last long My vacuum is too low under hard acceleration... Actuators partially engage leading to early failure.
I'd like to take an actuator apart, modify it so it's always locked in. Some loss of mileage? Other ramifications?
Ford F-150 (2004-2008) :: 2005 - Truck Starts To Sputter And Kick A Bit When Driving At Low Acceleration
I have a new to me 2005 F150 with 86,000 miles. When I am driving through town at a low acceleration or a constant speed at between 40 - 50 mph the truck starts to sputter and kick a bit. When I give it some gas the problem goes away. This gets worse when I pull my bass boat, and starts at around 30 mph. When I hook it up to a reader I get a P0316 code. Only code I get.
Also when I am driving through my neighborhood between 20 - 30 mph I get a noise that sounds like there is a plastic bag stuck under the truck. I have checked under the truck to see if the firewall is loose anywhere, but could not find anything. Other than those two issues the truck runs great. What these problems could be?
Ford 6.7L Power Stroke Diesel :: Truck Downshifted And RPM Went Up - Over Rev Code
I'm almost (1600 miles to go) home from my 8000 miles or so summer trip. More on that after I get home. Right now I'm curious about something that happened twice in the last two days.
Towing down steep grades in tow haul, truck downshifted and RPM went up but I don't think it passed 4000 and it didn't seem any higher RPM than many other downshifts. But, wrench lit up and truck threw an over rev code.
Ford F-150 (2004-2008) :: 2006 XLT Hard To Get Out Of 4WD Sometimes
I have a 2006 Ford 150 FWD XLT. So here is the problem. I sustained right front damage in an accident and 4WD worked prior to and after the accident (before going to the shop). Before the accident it would easily lock into 4WD but would sometimes have trouble getting out of it. When I received the truck back from the shop and went to use 4WD a week later nothing happened No lights no nothing. I tried it in neutral, drive and reverse. I took it back and they said it was the shift motor and not related to the accident so they couldn't fix it. So I just bolted a new one on and still nothing. I checked the solenoid and it appears to be working. I also checked the fuses and still nothing. The shop did replace the right front hub assembly.

2006 ford f150... Mine started out as a misfire problem which I first changed the plugs. I followed the Ford TSB and got all 8 plugs out with no problems. Still misfiring and setting a code for bank 1 catalytic converter inefficiency bank 1. By the way bank 1 is passenger side. After changing bank 2 because the guy at Advance auto said bank 1 was drivers side. Still setting misfire codes and for bank 1 cat. ineff.
So after installing new coil packs and 2 injectors, Still misfiring #3 and #1 and cat. ineff. bank 1. Decided to buy my own code reader, which is a must if you are going to try to work on these new vehicles. Decided to unplug o2 sensor to see where bank 1 really was. Thats when I found out bank 1 was indeed passengers side. Changed o2 sensors. Still misfiring. Decided to buy the true bank 1 cat converter.
Dropped old bank 1 cat and found all of the internal workings all broke up and clogging converter. Truck runs like new. I spent 178.00 for bank 1 converter at pep boys. After spending O approx. 600 in other parts that didnt fix it. I think the spark plugs not being changed until 115000 miles caused the converter to go bad. Buy a code reader and it makes it a whole lot easier to diagnose your problem yourself. and save a whole lot of money throwing new parts at it.
Ford F-150 (2004-2008) :: 2006 - Backfire Under Load During Acceleration
I have a 2006 ford f 150 with a 5.4 Triton 3v engine and every time I floor it and the engine reaches 3000 rpms the truck backfires and looses power. Sometimes it wont pass 3000 rpm it just stays there and backfire and have no power. Sometimes the check engine light flashes...... I took the coils off and looked at them and they all looked pretty clean. Also the truck idles rough and sometimes when it cruising at low rpms, and I give it a little gas the truck will randomly misfire and shake hard. also the engine sounds like a diesel engine........ What might be wrong.
View 6 RepliesFord F-150 (2004-2008) :: 2006 4.6L - Hard To Start When Its Below 50F Outside
I have a 2006 4.6L that's hard to start when it's relatively cold outside.
Normally, when it's warm outside, I can barely bump the starter, and it starts right up. But when it's cold outside, it usually takes 3 or 4 2-3 seconds of cranking before it starts. Even then, it has a really rough "about to die" idle, until about 10-15 seconds, and then it idles without a problem. Once it's running, it runs great.
It has 79k miles on it, and all I've done to it is put in a throttle body spacer, and a K&N filter. I've read a few posts from people that have had similar issues, that had K&N filters, but their problems have been more consistent. Mine only seems to happen when it's first started.
As far as I know, the plugs have never been changed, as with the COPs. I've heard about a vacuum line running to the throttle body may be the culprit, but haven't been able to find any more details on that, like where the line runs to, possible replacement part number for it, etc.

Ford F-150 (2004-2008) :: 2006 Truck Won't Restart After Shut Off?
I've got an 06 F150, 5.4l crew cab lariat. So to start, I had a programmer screw up my ECU, so when I got it re programmed at ford, everything works except for the ABS sensors. I recently had someone break into my truck and broke my stereo when they couldn't get it out. So I was driving home from work the other day and lost my whole instrument cluster, windows wouldn't roll up or down, wipers worked very slowly until not at all. shut off the truck and wouldn't restart. I jumped it and started it. ran fine. with the exception of the previous problems. I noticed when it got dark out that my my taillights and head lights were on very dimly with the switch off. Also hearing a clicking sound coming from under the truck, at the back of the cab and front of the bed. the only thing electric that's back there is the fuel pump (i believe). I am at a complete loss.

I have a 2006 F150 5.4L 3V with 105,000 miles on it. Recently, it has developed a misfire that is progressively getting worse. It happens when the truck is in overdrive, with engine RPM between about 1200 to 1800. Cruising at this RPM the truck runs great. If I increase the throttle, I develop a pronounced misfire. Once the truck down shifts out of OD and engine RPM exceeds 2000 RPM the misfire goes away. I have never had the CEL light come on during any of these events. The truck has the original plugs in it AFIK. I have not changed them.

I just went out to move my truck to take out garbage and it cranks but doesn't start. It is 4.6L 4WD. I sprayed ether in intake no change. Checked all fuses all good. It has been raining pretty hard the last 3 days and it has been sitting in rain all 3 days. I checked for codes with a simple code scanner no codes. But the code scanner I used is not able to do KOEO or KOER tests. I know it needs new plugs but it has never sputtered or died on me. Has slight misfire but not engine stopping. I havnt had any check engine lights or problems before.

I have an 06 F-150 4x4 with the 5.4L Flex Fuel V-8. The truck has 133,000 miles on it. This morning, the truck was very hard to start. It took me 4-5 times of cranking the engine for 30 seconds or more before it started. Once it starts, it idles fine. Out on the road, the engine cuts out and the truck bucks pretty hard. The truck doesn't die, and the issue is intermittent. I changed the fuel filter less that 10,000 miles ago. The Check Engine Light has NOT come on. What could my problem be?
View 7 RepliesMazda - Miata :: Downshifted From 5th To 4th / No Acceleration When Hit Gas Pedal
So, something odd happened to me today while driving. I was getting off a highway after about 250 miles of driving, downshifted from 5th to 4th, and when I hit the gas pedal after shifting, nothing. No acceleration. I shift back to 5th. Still nothing. Try revving in neutral, also nothing. I come to a stop on the exit ramp and try to start the car up. It starts up, hits about 1k rpm and stalls. Gas pedal does nothing still. What's up with this? I had it towed to my shop.
Couple tidbits of info: just had the oil changed three days ago. Checked the oil and it seems fine. I have an aftermarket he's unit in the car and lately, it's been a little wonky. When I put use my automatic windows, sometimes the volume will mute for a sec.
My car is a 2006 Mazda Miata base model. 5 speed manual. Power windows but not locks. No traction control. No cruise control. 40,000 miles. Oil changed regularly with full synthetic.
