Just read the comsumer report "Annual auto issue", it reminded me the hesitation issue with the 2.0T (... page 70: We found the Passat hesitates slightly on takeoff from a rolling start..."). Is it a common problem with the turbo engines? it could be deadly when you change lanes on a busy highway.
View 7 RepliesNoticed A Slight Hesitation On Take off?
View 23 RepliesI've noticed that on cold starts after work, or in the mornings in start up my Santa fe's really rough at idle.. I'd like to say even slight hesitation when I take off.. I notice a drop in RPM and lately harder shifts out of first..
My sf is the 3.5 AWD w/ nav it's a month old with 2900 Kms on it..
I'm having a sight hesitation @ around 4100rpm when getting on the highway, it is not noticeable in 1st or second, a bit in 3rd, and 4th though. It seems almost like the acceleration stops for 1/2 a second then continues normally.
2007 2.0T FSI, automatic. 71,000KM ( like 40k miles?)
New plugs(problem existed b4 plugs)
new air filter ( K&N Drop in )
new oil & was just seafoamed.
This problem was there before all of that too. What it could be?
My isf for couple months now and love the car. I have an 08 which only 7k miles on it. Lets say at a stop I start to accelerate, I notice a slight hesitation before it picks up around 1-1.5 rpms. Under hard acceleration I don't notice it, but with nice and easy acceleration that slight hesitation is kinda annoying. Not sure since car has such low miles on it if I need to run fuel injection cleaner or something, of if something else could be wrong. I kinda mention it to the lexus service manager and he said something that next time I bring the car in that he'll let the mechanic do a tranny ecu update of some sort? I didn't know that there was such a thing.
View 14 RepliesA couple questions I have about my truck. I'm still new to the F150.
First, my truck has an Ecoboost and I have a slight stumble/hesitation when you start the truck cold. It clears up within 10 seconds and doesn't seem to affect drivability whatsoever.
Second, it seems that only my driver side mirror has the "dimming feature" to it. Is this normal?
I have a 2010 with about 166k miles. I am getting a slight hesitation at slight acceleration or constant speed. It does not matter if it's on highway or freeway speeds. Now I am not sure if this in junction with me changing the PCV valve, cleaning the EGR pipe, or cleaning the TB for carbon recently. It started happening a week after it though.
View 19 RepliesI have a 377 gti 2002 and just the other day i had some hesitation on take off. it sounded like the engine was cutting the fuel, at the time i had an o2 sensor code so i replaced the o2 and got new spark plugs while i was at it. it was still hesitating and cutting out so i figured it might be the maf because ive already replaced it once, i cleaned it and still doing the same things. i called my local vw/audi shop (audub) and he said it might be the pcv valve. i checked to see if there was air sucking in through the oil dip stick and the oil cap. its running just fine at idle and it seems that in first and second gear that its hesitating at 1000-2000 rpm and the higher gears are fine. could a leak cause this or is the pcv system bad?
View 7 RepliesI have my 1995 Volvo 940 Turbo that stalls in reverse and hesitates on take off. The following is a breakdown of what has been done so far:
1. Initial Issue from March to October is hard starts; it would take 15 minutes or more to start car; it would be longer sometimes in cold weather.
2. Car would have erratic idle after startup; car reaches operating temperature before movement; car would bog down in idle and die only in reverse; initial acceleration from takeoff is slow;
car runs fine once out of first gear from takeoff; car bogs down on braking with idle lowering; sometimes car stalls at braking; gas is sometimes tapped slightly to stop stalling.
3. Issue of hard start would be intermittent; it would be less prominent in hot weather and more prominent in cold weather.
4. Sometimes in rain or wet weather, car would stall and sometimes backfire; Distributor Cap is normally changed.
5. By October, a no-start condition occurs.
6. Car starts now, idle is not erratic; car would bog down in idle and die only in reverse; you barely tap gas to keep from dying in reverse; initial acceleration from takeoff is slow; car
putts a little; car runs fine once out of first gear from takeoff; exhaust flows strongly; takeoff slightly improves incrementally with continued operation; car bogs down on braking with idle
lowering; sometimes car stalls at braking; gas is sometimes tapped slightly to stop stalling.
7. During idle or operation, sometimes coolant will boil in reservoir; toggle fan brings temp down to normal in between fan cycles; toggle fan keeps coolant temp normal in really hot weather.
The following parts have been changed and are still prominently new:
-Ignition Coil
-Spark Plug Wires
-Spark Plugs
-Distributor Cap (Initially Sealed With Sealant, Condensation Issue When Raining Causes Stalling)
-Rotor Button
-Condensation Cap For Distributor Cap (No Need For Sealant Now)
-K&N Air Filter
-Turbo Intake Hose (Original Had Disentegration In Spots)
-Exhaust Manifold Gasket (With New Locking Nuts and Sealant On Manifold Side, Not Block Side)
-Power Stage (Ignition Module or Ignition Stage Amplifier)
-Engine Coolant Temperature Sensor
-Gauge Temperature Sensor
-Knock Sensor
-All Vacuum Hoses
-All Coolant Hoses (Including Oil Cooler Hoses)
-Fuel Pressure Regulator
-Oxygen Sensor
-Catalytic Converter (Honeycomb In Original Rattles, Discovered Gone When Removed)
-Exhaust Resonator/Central Muffler (Original Damaged By Honeycomb, Sounded Like Broken Glass, Baffles More Than Likely Clogged)
-Idle Air Control Valve
-Starter Solenoid (Starter Tested Good)
-Power Brake Booster (Original Replaced, Failed 2 Out Of Three Brake Pedal/Vacuum Tests)
-Battery
-Radio Suppression Relay
-Throttle Position Sensor
-Fuel Filter
-Timing Belt and Tensioner
-Crankshaft Position Sensor (Last In Chain, Resolved No-Start For Now)
The following are checkpoints, mods, and maintenance:
1. Modded Airbox for more airflow, no codes present from OBD before or after
2. Cleaned MAF Sensor with MAF Sensor Cleaner, no codes present from OBD before or after
3. Checked EGR Valve - Diaphram not broken, free movement, appears functioning
4. Had EGR Pipe Rewelded - Pipe broke from connection to throttle body, completely sealed and functional, Minimal Carbon Removed
5. No codes from EGR temp sensor before or after
6. Checked EGR Vacuum Controller through OBD - appears functional
7. Checked Fuel Pump - Repaired frayed hot wire, sealed, pump fully functioning
8. Checked Fuel Pump Relay - Functioning
9. Properly adjusted Idle Air Speed - Steady Between 700-800 RPM
10. Checked EGR Pipe to Exhaust Manifold - Minimal Carbon Removed
11. Cleaned Throttle Body with Throttle Body Cleaner - No Soot/Carbon exiting system
12. Created Toggle with Fuse in between connection, connected to slot in fuse box, cuts off with car, slight battery drain issue before and after installation
13. Checked oil in case - oil change still new, no milky appearance suggested head issues
14. Removed and cleaned breather box - no oil deposits clogging operation
15. Checked charcoal canister - stalling in reverse happens with and without it connected
16. Checked muffler during disassembly of exhaust system - no honeycomb/debris present during testing
17. Car is at Top Dead Center - Timing
18. Fuel Injectors tested fine with OBD and Pressure present at rail
The following parts have not been changed yet:
-Charcoal Box
-MAF Sensor (No Codes)
-EGR (No Codes)
-EGR Vac Controller (No Codes)
-Compressor (No A/C, issue with stalling is unrelated)
-Power Steering Pump (Slight squeaking on rotation, PB Blaster in bearing area confirms, issue with stalling unrelated)
Other Issues : Slight battery drain coming from somewhere in the car, have to remove negative from battery for now
I'm taking my new to me 2011 KR 6.7 I've had it 1 week, to the dealer tomorrow to get them to look at the hesitation on takeoff. I have read on here that not all trucks are doing it. There is 25500 miles on it and have been averaging 15.3 mpg empty, is this about normal for what people are seeing? I'm running the 3.31 gear ad I thought I would get better mpg. This truck was built in Feb. of 2011 would it have the 400/800 settings or would it have to be flashed?
View 14 RepliesI recently had the Blue Spring installed on my 04 X. After having it installed I still noticed a lot of hesitation on take off, and after a few seconds of trying to take off it kicks out a large cloud of black smoke and away she goes. The problem is very noticed when at the bottoms of hills it seems powerless and makes a wierd noise from the drive side of the engine bay, until I press the pedal enough to make it downshift then comes the large cloud of black smoke and she climbs up. All I know is I'm getting worse fuel economy then I should get and something just doesn't feel right when driving the X. The truck doesn't feel like it missing at all so I don't think it would be injectors especially as They are all brand new and less than 6 months old.
View 12 RepliesI've recently been hearing a grinding/vibration noise on takeoff. I only hear it pretty much as soon as my foot comes off the brake, when the car is in drive, and the car gets its first bit of forward engagement/movement. It seems to only happen when the DSG engages in drive, before I put my foot on the gas pedal.
The closest thing I can say it sounds like is an exhaust rattle, but way less violent/not metal on metal sounding.
Is it normal for the GX 470 to roll backward on a slight hill when in drive and foot off the brake?
View 3 RepliesI've been catching up on some minor things with my car and have gotten to this one issue I've been having. When I take off from a stop I get a very slight click. Not every time but most of the time. It's a 2005 Elantra GT 5 speed. I replaced both axles due to torn boots. There is no play in the front end whatsoever, so I have ruled out ball joints and tie rod ends. Anything else I should look at?
View 15 RepliesPurchased my first used Super Duty 2011 F250 6.2. Love the truck. This is my 3rd ford truck. I get home from work, so the truck is warm. Sit for 20 min, then leave to take the kids to their games. After turning onto the street then accelerating power is lost for 1-2 seconds, then the truck continues to accelerate. If I let off the pedal, then the truck will slow down, if I hold the pedal position of push down it does nothing. This is going to drive me crazy. Not sure if this is a TCM reprogram issue? It only does this on the initial take off. I want to start playing with my new truck, but want to fix this bug first.
View 5 RepliesI have a 2005 F150 5.4 and I recently got a p0175 code. I've replaced the M.A.F. sensor, fuel injectors, fuel filter, new plugs, coils and checked the vac lines but I'm still getting a p0175 code. Ive reset my P.C.M. and the code stopped for 2 weeks but returned later. The truck runs fine when I erase the code but when it returns it hesitates on take off and has a slight shake like a misfire and it makes a bubbly popping sound from the exhaust. Im at a loss of what to do next! Could this be a code stuck in the P.C.M.? My mechanic thinks it may be the cam phasers!
View 5 RepliesHaving problems with start up? It feels like the engine wants to stall when I start it and as if the flywheel is so heavy. It also like jerks the car. You can clearly tell it isn't a smooth start up. Maybe the starter?
View 10 RepliesSo I have noticed a slight hesitation from a stand still. I press the gas and there is a slight delay(maybe less then a second) before something happens. It also does not do it every time, it is pretty random.
View 4 RepliesWhen upshifting into 5th gear there is a slight hesitation before actually going into gear? I do not have this issue with any other gears!
View 24 RepliesI have a 2009 Tiguan 2.0T Gas 2WD Tiptronic Auto.
I noticed a while back on a cold morning that at first start the idle would seem off a bit.
I only would notice it for about a couple of minutes and then it would smooth out as I began to drive.
Lately that still happens some but mainly I have some hesitation or slight jerking as I accelerate now.
Mainly it will do it while starting to take off slowly/ when pulling a hill/ and when having to maintain a low speed behind many other cars.
I can counter act it a bit by stepping harder on the gas pedal(when there's room) and getting the RPM to go and stay over 2000 like on the highway.
If it is under 2000 RPM you can notice it pretty well.
I am concerned as I have not had this problem before and it is very well maintained and cared for.
Though it is likely due for a tune up...
What could be the most likely cause? I don't really want to take it to the dealer first as they would want a fee beforehand just to check it out.
It had a check engine light on for just a minute one day but it did not stay on.
If it stayed on then I could get the parts store to check it using the OBDII scanner.
Phaeton 3.0 tdi ... For some time i have been noticing that the car has a slight hesitation when changing gear from 1 to 2 and barely noticeable from 2 to 3, but as the car gets warmer the hesitation becomes shorter, I don't know if it really is a hesitation , it mostly feels at light acceleration before the oil gets to operating temperature and feels like it slips for like a half second before engages second gear , but as the car warms up it gets better , the car has about 230.000 km , since i bought it i put 50.000 km and did not change the transmission fluid and i guess that before me no one changed it, VW says that the atf should not be changed and many people say that it could make it worse, what the problem is and should I change the Transmission fluid ?
