Ford Super Duty (1999-2016) :: 2004 F350 - Shudders While Slowing Down?
My 04 F350 has a bad shudder when slowing down between 30 and 10 MPH. Not so noticeable at other speeds and almost nothing while speeding up. How to fix?

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.

View 2 RepliesFord F-150 - 1997-2003 :: 2001 - Shudders At Low Speed
2001 S-Crew, 4RW70, 5.4L, 189,000 miles. This started two years ago and first became apparent when I made a hard/panic stop. In fact, the first time it did it I was going to go through a traffic light and hit the brakes at the last second so I didn't actually run the red light. The truck shook like it missed for a second. That was unlikely as the coils and plugs were relatively new.
Here's what it does. When sitting still, in gear and you let off the brake but do not touch the accelerator, the truck will start to move as expected. It immediately shudders as it passes through 3-5 mph and then stops. It shifts through all the gears flawlessly, has no sign of the dreaded torque converter issue. It also does it as you come to a stop- as you come to a full stop and the trans shifts into 1st it shudders just as you come to a halt.
It started doing two years ago and never progressed. It's been the same until just recently when the weather got warm again. It's gotten a bunch worse in the last week and now the truck actually feels like it is idling rough sitting at a stop. (It's not- it's running fine.) But it feels like clutch chatter in a manual. Fluid changes have been routinely done every 30,000-40,000 miles, trans fluid is clear and not burnt, temps are normal.
As I said, it behaves perfectly the rest of the time and even tows my 20' 4,000 lb. boat just fine. Just that initial moment of take-off and at the stop. If I hit the gas when taking off I never feel it. Likewise, if you shift into neutral and coast to a stop it doesn't do it.
Elantra XD (2001-06) :: 2002 - Shudders And Doesn't Accelerate Well When Going Uphill
I've been having problems with my '02 Elantra. It shudders and doesn't accelerate well (or at all) going up hill, or attempting to accelerate quickly (like passing a car on the interstate). If I try to push it through these situations it will run worse, engine light flashes, and sometimes will stall. In the past, when it stalled, it would start up again in about 30mins or so.
Codes it has thrown were P0304, P0303, and P0420.
When I took it to mechanic, he really couldn't figure it out. He ended up testing and replacing fuel pump motor in November. Got it back and within a few days it was throwing same codes and having same symptoms.
Everything else from this point as been DIY. I bought a manual, researched these forums, learned as I went, and did the following myself:
I changed the spark plugs and wires. Still ran as described above but at this point when the engine light comes on, I am only down to the P0304 code right now.
Thought perhaps it was a vacuum leak. I have very few tools, and Autozone said I could use seafoam as a means to tell if I had a leak if smoke came out of vacuum lines as I put it in. I tried this, none came out of vacuum lines that I could tell. I drove it after seafoam, some white smoke came out tail pipe from solution but dissipated after driving a little while, and then I had the shuddering issues and loss of power while driving the interstate. It literally would act like I wasn't pressing the gas peddle, then suddenly surge as if it realized I was... engine continued to run until I pulled over and then it stalled. Normally it would start right back up after 30mins or so. But this time it didn't, I had to tow it home.
With a crap load of starter fluid and jamming the gas pedal, I finally got it to start. It ran horribly at idle, had a weird knock. So I didn't drive it and did the following instead.
I replaced the coil pack.
Replaced crank position sensor.
I confirmed that I have spark on all 4 cylinders.
There are no obvious oil leaks (nothing on garage floor and I don't see any obvious signs of wet oil on engine or smoke when it runs)
Temperature is fine, coolant level is normal & hasn't needed refill or topping off.
I pulled the fuel pump again, noticed that the fuel sock had holes and was full of muddy/pasty type crap. Gas was dark, cloudy in spots, and appeared to separate in some areas.
Replaced fuel sock.
Syphoned gas.
Thoroughly cleaned out gas tank.
Put premium gas in.
Manually cleaned fuel injectors.
Reassembled and it started right up, runs strong, no more weird knock, but the other symptoms start to reappear... the shuddering, loss of power, and stalling. Its intermittent... sometimes when I jam on the gas peddle, sometimes when I'm cruising at low speeds. I can force it to stall by jamming on the gas peddle to the floor, acts like it's choking, engine light flashes, lose power, then it stalls. Pretty much every time I push it like that.
I can continue to limp it to Autozone for codes, but the engine light currently isn't on.... and it usually takes it a hard drive pushing it through the symptoms for the light to appear, and it's always been the P0304 code at this point.
Is there anything else I can do from home with no special testing equipment?
Is there a part or sensor that would cause these symptoms and NOT throw a code other than the misfire?
Prius (2001-03) :: 2002 - Got Code 3025 - Shudders Very Badly - CEL Came On?
I own a 2001 prius and work on a lot of toyota . I am looking at friend's 02 prius that he got with a bad inverter . To make a long story short I checked the codes before we started and got code 3025 which can translate to a bad inverter if I am correct. The inverter pump was bad so we changed it and flushed the used inverter after we put it in. The "new" inverter seems to be working ,but we still have a major problem with the transmission I believe. The car will move , but it shudders very bad when you put it into drive and reverse both.
It appears like the engine is turning over with the transmission ,when the engine is hot and shut down and running on battery only. Yes the check engine light came on ,but have not had time to pull them yet.I know ,I know .its hard to give me info with no codes. The big question was ,is it possible for the engine to rotate when you drive the car in battery mode? It sounds like the engine is actually rotating and the engine will also rock back and forth with the car driving real slow. I know this will end up needing a transmission.
Ford Transmission :: 2001 F150 Truck Shudders When Letting Out The Clutch
I have a 2001 F-150 4.2L 2WD LS with 102k miles. At 95k miles, the clutch slave cylinder started leaking fluid. So, I had my local garage replace it. And while they were at it, put in a new clutch. That is when the trouble started.
I cannot let the clutch out like I used too. When letting out the clutch from a dead stop,the rear end now shakes, shutters, and if it is really bad, the rear end starts bouncing. To minimize the shakes, I have to keep the engine below 1000rpm until the clutch/1<sup>st</sup> gear is fully engage. It is worst when there is a load on the truck like going uphill, or a sharp turn for a dead stop. After the truck gets rolling, I don’t notice the problem when shifting gears.
I have been babying it for 7k miles and it has not improved. What is wrong? Did I get a bad clutch job?

This just started over the weekend. It's stalling. It does it mostly when I let off the gas and start slowing down. If I give it gas, it seems to straighten out for a minute. It has done this a couple of times while driving also. It sounds as if the engine speeds up and then slows down and stalls. The check engine light is on also. It went out yesterday and then popped back on today.

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?

View 4 RepliesFord - Escape :: 2001 - Alternator Light On Intermittently - Crankshaft Slowing Down The Belt?
The alternator light on my 2001 Ford Escape 3.0L comes on intermittently. I've replace the alternator, belt, tensioner, and battery. I've check the wiring and the ground and there are no noticeable issues. When I first start up it never comes on. After about 30-40 minutes of driving it will start to come on intermittently. I've noticed that it always shuts off when taking off from a stop. I have the most trouble with it coming on while driving around the city and little trouble while cruising on the highway. I'm completely stumped. Is it possible for one of the other pulleys to be causing this if for instance some bearings were going bad and it was binding up or problems with the crankshaft slowing down the belt?
View 13 RepliesFord Super Duty (1999-2016) :: 2001 - Stalls While Slowing Down / At 15 Mph - Vacuum Line Burnt?
I have a 2001 F-250 7.3 diesel with an automatic trans. Over the last couple of months it has stalled 3-4 times while driving, always when slowing down but even at speeds of 15 mph or so. I did find a burnt vacuum line the other day. It comes out of some type of relay box located behind the battery and in front of the starter solenoid relay and is mounted on the fender. It has an electrical plug in the top and two vacuum lines at the bottom. I am hoping this is the cause of the truck dropping off of the idle circuit? But I don't know what the unit is so I cannot order the correct replacement lines.
View 9 RepliesSanta Fe (DM - 2013+) :: Hesitation / Idle Dips Up And Down
My 15' SFS 2.4l has been doing this since around the 10,000km mark, it now has 26,600Kms and it seems that when I come to a stop at a light the hesitation has gotten worse! When I mentioned it the first time to my Hyundai dealer they said on one of my oil changes they would put in an additive to clean the injectors (I said it shouldn't be doing this as it is a brand new vehicle) and now other the last 16,000kms since the additive was put in I'm finding it is getting slightly worse. The idle dips up and down a very Mina's amount resulting in almost what would be a cat purring sort of vibration (weird way to describe it) but that's honestly what it's like. I checked to see if there was a cat stuck under my hood but their was nothing (I'm kidding).
View 17 RepliesPrius (Gen 2) :: Passenger SRS Only Works When Temperature Dips Below Freezing
When the temperature is above freezing, the Passenger Airbag light is always "Airbag Off" and the flashing red light does NOT engage, regardless of whether a passenger is sitting in the seat and regardless of whether the seat belt is latched.
When the temperature dips below freezing, the system works as expected:
No passenger: light is "Airbag"
Passenger with seat belt: light is "Airbag On"
Passenger with no seat belt: light is "Airbag On" with red flashing seat belt sign
I can't imagine the issue is related to a component inside the passenger compartment (the seat weight or latch sensors), as the temperature inside the vehicle is usually above 60 F. That said, are there any components outside the compartment (under the car or in the engine compartment) that could be causing this behavior? Is this a water freezing/unfreezing issue, caught in some wiring somewhere?

View 9 RepliesGolf/GTI VI :: Power Dips For About A Second And Then Comes In When Try To Change Gear Quickly
I have a problem that I can't work out. The problem occurs when I try to change gear quickly (say for a 1/4 mile run). between 2nd and 3rd, as soon as third engages, the power dips for about a second and then comes in. Its not like the revs drop, its just for that second it feels like the turbo is spooling up or something and the car is at best pulling like it has the low range torque of a Honda!
It doesn't happen always, but i would say at least 50% of the time. I have been driving stick for 15 years and have had 3 gti's but none of them have done this. I have tried to change gears at different rpm and experimented with keeping revs up and different release points for the clutch but it doesn't seem to make a difference. my friend also tried it in my gti and he felt the same thing.
Is it a gti thing? maybe the turbo spooling up? I have noticed it since stock clutch and apr stage 1, I honestly thought the clutch would fix it but it hasn't. I have a mk6 gti 2012, apr stage 2 (carbonio intake) with dxd stage 2 daily clutch, short shifter and BB downpipe. Working towards k04 but not there yet!
