Ford F-150 (2004-2008) :: Significant Shudder At Highway Speeds When Starting Up An Incline

I have an '05 F150 5.4L with 110k miles on it. Bought it used about 2-3 years ago and have had on-going ignition system problems. The current problem is a significant shudder/shake/vibration that occurs when driving 50mph+ (easy to reproduce around 65-70) on the freeway, when starting up a minor, but noticeable incline. This is an incline that doesn't require much additional throttle, and this trouble occurs with cruise control on and off. the truck starts shuddering pretty rough during the incline. However, if I release the accelerator (and go up incline with slightly lower speed) or give lots of gas on accelerator the shudder usually stops. The shudder always clears after the incline when returning to flat road and just cruising.

This occurred on a recent trip a few times and I pulled the following codes (in order):

P0356 (once) : Ignition Coil F (6) Primary/Secondary Circuit Malfunction
P0302 (recurring): misfire on cylinder 2

I have since purchased and replaced the coil on #2. This did not resolve the problem. I have replaced coil on #6 in the last year...

Because I saw a suggestion somewhere on the net around this problem while searching, that this could be related to OD, I tried disabling OD and enabled OD on an incline today to test after replacing COP on #2 and it seemed to resolve the issue to turn OD off. Not sure if related...?

Other observation: Cab of truck often smells of gas just after starting the truck. Mentioned this to the shop, but they didn't find anything obvious.

Short history of codes and work that has been done:

Sometime in early 2011: Ford service dept did this work.
First failure was coil bad on #7. Tech swapped 7 & 8 to verify the problem followed the coil. Then when the problem DID follow the coil, he replaced #8 with new.

05/2011 MacKenzie Ford changed all plugs

12/2011 - swapped out COP on #7.

02/2012 - P0306 - Now, COP #6 is reported as bad.

November/December 2012
P2104 P Throttle Actuator Control (TAC) - Forced Idle
P2112 P TAC Stuck Close
P2111 TAC Stuck Open

I did throttle body clean - removed it and used TB cleaner. replaced...

Late December 2012 - while driving on freeway at speeds 50+, but easily reproduced around 60 after starting up a slight incline. symptom is heavy shudder/shake. Possibly resolved by turning OD off.
P0356 (once) : Ignition Coil F (6) Primary/Secondary Circuit Malfunction
P0302 (recurring) : Misfire on cylinder 2

Ford Transmission :: 1990 E250 - Shudder When Starting Off From A Stop

I am not the original owner of this 1990 E250 cargo van with a 302 in it. I am trying to troubleshoot this shudder I am having. It only happens when I am just starting off from a stop. Every other place the tranny runs and shifts great. I trying to find a starting point and after reading a bunch in a bunch of different places, I am confused as to the tranny I have or even had.

It has in big bold letters METRIC on the bottom of the pan. It also has Automatic Overdrive and Ford on the bottom of the pan also. It is a 14 bolt pan with the two rear corners of the pan chamfered off. I see now it is DEFINITELY the AOD installed and NOT the AODE. The thing is my steering column is labeled 1 D and OD. That is a 3 spd overdrive to me. What the heck is going on? How can I tell what the tranny was that came out of the van?

When I look under the van at the shift linkage, you can definitely tell the linkage is colored red which to me looks like somebody has been down there playing around. Is it possible to put a AOD into this van with the steering column the way it is? Could this be a reason for my early shudder at starting off from a stop? Once I put my foot in it or get moving at a quicker pace, the shudder goes away. Something is not right with the way this tranny is set up. I am not even sure where to start.

Prius (2010-12) Fuel :: How To Do A Steep Uphill When Engine Is Cold

The road my house is on is a steep hill. In the morning when I first start the car I have two choices. I can jump right on the hill and start climbing. Or I can drive down the hill and do a little quarter mile loop before I start climbing the steep hill. Which approach is best? Or is there a better way to handle this?

Ford F-150 - 1997-2003 :: 1998 - When Parked On An Incline Surface With Front Uphill Won't Start?

I have a 1998 F-150 V8 4.6L. Currently has about 83000 miles. I have had this problem twice now. When I park on an incline with the front up hill the engine will not start. It will crank like it is trying to start, but it sounds like its not getting enough fuel. Both times my tank has been nearly full or 3/4 full. Just put on a new fuel filter and the old one was still clean. ( I could blow through it with ease). I think it is the fuel pump.

Golf/GTI VI :: DSG Shudder When Stopping / Starting Off

I just picked up my new GTI and drove it 300 miles home. I did notice one potential issue that will need service attention. There is a mild but very noticeable shudder when slowing to a stop (gently slowing to less than 5mph). It is also mildly noticeable when taking off slowly but much less so.

The best description I can come up with is : Shudder that occurs when you slow to a near stop in a manual transmission car without pressing in the clutch? That little shudder that reminds you to put the clutch in before you stall. That is what this feels like. It doesn't shake the whole car but it is very noticeable.

Subaru - Tribeca :: Shudder Like Driving Over Small Bumps On Road When Going Up Slight Incline

2008 Subaru trebeca suv with only 62000 miles, when going up a slight incline in drive you feel quite a shudder like you were driving over small bumps on the road. This is my daughters vehicle so she phoned about 400 miles from were I live & told me what I said above. I told her it sounds to me like the torque converter is not unlocking. And if it is the converter not unlocking would that be a very expensive repair ?

Golf/GTI VII :: Squeak Like Noise When Clutch Engages In 2nd And 3rd Gear

Currently driving a GTI mk7 autobahn 6MT, this is my first manual transmission i have owned.. and have a question about a squeak like noise i hear when the clutch engages in gear 2 and 3.

This does not happen all the time, however i noticed that some / most of the time when i slowly let the clutch out in gear 2 and 3, right after the clutch engages and i let it out the rest of the way, it makes a squeak kinda sound.. almost like springs contract / retracting, i can also slightly feel it in the pedal.

Question is ...is this some what normal? i have never owned a MT car, and cant remember if such a thing happened while driving friends / family MT in the past..

Ford Ranger / B-Series :: Starting From A Stop In 1st - Truck Bogs Down When Letting Out The Clutch

Started up my truck today, accel pedal didn't want to move, after giving it some more force it eventually became "unstuck". Now, the real issue I'm having is from a dead stop, in 1st gear, as I'm letting out the clutch the truck boggs down as if I'm not trying to accelerate. I'm giving it as much as I normally would as I'm letting out the clutch but the motor will either die or take a couple seconds before it starts to go. Once I'm moving I don't notice any problems clutching through gears. The check engine light IS on now, however I don't have any diagnostic gear or really any tools for that matter. 1998 2.4L 5-speed...

Golf V R32 :: Shudder When Move Forward From Stop

When I am stopped and remove my foot from the brake, the car shudders as it moves forward. This happens when I do not give it any throttle. The idle forward is jerky...like it pulses. It feels like when you let the clutch out too slow on a manual trans. The DSG in all it's techno-glory should be able to release it's clutch(s) smoothly one would think? It happens when I am waiting in line at a stop sign or in traffic...anytime I need to idle forward slowly. I've been driving it for less than a week...it has 320 miles and I'm keeping it under the limits for break-in (BORING). Anyway, the thought of taking it for service at this point is depressing..

Golf/GTI VI :: Slight Shudder When Braking And Coming To A Gentle Stop

Picked up my MK6 GTI DSG last Saturday. I have noticed a slight shudder when braking and coming to a gentle stop. At first I thought it may be the brakes bedding in so I kept it over the weekend. By today there's still no change. Is it normal for DSG transmission stop like this? Because I have never driven DSG transmission.

Golf/GTI VI :: Squeak When Pushing Gas Pedal During Stop And Go Driving?

So, just recently I noticed my car squeaks when I push on the gas pedal. I've researched up and down and can only seem to find that it is "Normal". It only happens at very low speeds (Stop and Go). I've read it could be anything from exhaust leak, DSG/ Tranny, belts or cv joints but nothing i've read seems to be exactly what I'm experiencing.

Cadillac - Escalade :: 2009 - Shudder Going Uphill?

I own a 2009 Cadillac Escalade (no I don't write rap tunes) and for the past 5 years it has been an excellent vehicle to drive. It still is, but under certain conditions I am experiencing a shudder which lowers the confidence that I usually have in my vehicle. Specifically, when I am climbing a hill and the transmission is in a higher gear, say 4th and the RPMs are relatively low, say 1800, I feel a shudder as the car goes up the hill. When I let my foot off the gas the shudder stops. If I manually shift into a lower gear and raise the RPMs, the engine responds with power galore and I climb the hill without any effort and without any shudder (most of the time). The engine is smooth and is not sputtering when this shudder happens. I do not hear any unusual sounds under the car when this happens.

I took it to the GM dealer and they did all they could (analyzed the car for codes, monitored fuel flow rates, searched for GM bulletins, etc) but their response was "we experienced the shudder but cannot find the issue - bring it back when it gets worse". I read that BG44K will do a good job of cleaning the fuel system in the engine so I tried that but nothing changed. I have about 50K miles on the car and did my 50K maintenance just before a cross-country trip; on the way back from this long trip is when this issue started. The 50K maintenance included changing the transmission fluid and cleaning the filter (not replacing it), changing the differential oil, the transfer case oil, engine oil and filter, inspecting the vehicle, etc. I will continue to drive the vehicle and will bring it back to the dealer if it gets worse, but I'm wondering what I'm supposed to do if it never does and I continually experience this shudder. Or what happens if it gets worse all of a sudden and I'm unable to drive the car up a hill at all?

Golf IV / Jetta IV :: 2002 - Stalling / Occasionally Shudder At A Stop Light

2002 1.8t Jetta Wagon with the automatic transmission. They've had it for about a week now and we've been trying to iron a few problems out. Mostly cosmetic until the last couple days.

The coil pack harness is trash. I bypassed a couple of the extreme cracked wires in attempt to keep it going until the new one comes in hopefully at the end of this week. We put new plugs in but only afterward did we find out that NGK or VW is the way to go. We put autolite iridiums in.

New fuel filter, however, the line connecting the tank to the filter will not click into place completely. We are able to start/drive the car without the line popping off from the pressure, but you just have to tug on it with your hand to get it off, no need to depress the clip.

The car seems to run better cold. Once it is warmed up and you've been driving around town for 10-15 minutes is when the shuddering starts. It ONLY dies when in Drive or Reverse while at a complete stop. The idle drops down to 400 rpm or so, you can't rev the motor/drive. Sometimes it will come back up to normal and you can go, sometimes it will go back and forth but you can't get any power to the wheels. Sometimes it will drop the RPMs and shudder at 400 for a couple seconds then just die. It always starts right up without hesitation. In park/neutral the idle is still slightly erratic, occasionally bumping up to around 1300 rpms for a second or two then back to around 900 or so.

When we bought the car, we test drove it and it was fine. Of course that is how it works out. They drove the car for about a week. In that time, it shuddered and died once, and would occasionally shudder at a stop light but there was no issue driving it or loss of power when accelerating.

What I'm wondering is if we should go ahead and order the R8 coil pack and spark plug kit from HSTuning. I'm hoping that the harness fixes the issue, but if it could be cheap spark plugs or a coil pack going out, I'd like to get it all done at once. My main concern is the possibility that it could be the transmission. The symptoms feel like loss of power, not slipping, but still, I'm worried that maybe it could be the issue.

Golf/GTI VI :: Clutch Starting To Slip / Cannot Handle It

I have a 2012 GTi. I just got the stage 2 unitronic flash on my car and now my clutch slips bad. I know i will need to replace my clutch. It was starting to slip before the tune and now it just cant handle it. The shop I went to recommended a South Bend Stage 2 Clutch kit (single mass). Its a daily driver and want something that will last and hold up to 325ftlbs of torque. I do think i want to go with the single mass clutch though.
