Lexus GX 2004-09 :: Slight Hesitation / Surge While Driving At Constant Speed?
my 2006 GX has 95000 miles and recently i've noticed a slight hesitation followed by a slight surge in speed while driving at a constant speed. it almost feels like i'm pushing the accelerator then releasing it. its a very mild difference but i'm guessing tranny and have 5k left on my warranty. it occurs at a variety of different speeds but most noticeable at about 35-40mph and up around 55mph.

Had this truck a few years now, and it has always had a slight miss/hesitation and maybe a few codes. The timing chain skipped a tooth and the truck was down for about a year. I have 4 other trucks, so it wasn't a big deal. I finally had time to put a new oil pump, chains, guides, tensioners, phasers etc. The truck actually runs very well and quiet. But, now misses far more than I remember it doing.
When driving in town constant at 25-30 mph occasionally it will loose power for a brief moment(<1 second) and then be fine, the security light on the dash turns on for a few seconds. It drives at 55-65 just fine, unless I am going up a hill or something else increasing the load.

CEL-
P0453 (fuel tank pressure issue)
P0351 (ignition coil a primary/secondary circuit malfunction)
P0356 (ignition coil f primary/secondary circuit malfunction)
The coil packs are new, and I have injectors on order. Also found this thing on the back of the motor, it connects to the fuel rail on the drivers side. Where it should go. I looked on my other trucks. But my other 04-4wd has a box by the battery it connects to, but mine doesn't have any of that stuff. And my 08 doesn't have anything like this at all.
And a pix of the truck in question.
Tiguan :: Hesitation Or Slight Jerking On Acceleration
I 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.
Santa FE SM (2001-06) :: Slight Hesitation During Acceleration Suddenly
Last night i noticed a slight hesitation during acceleration. Today i had driven around in town for awhile and did not notice any hesitation. When i got onto the interstate I pushed down the peddle to pass someone and it did nothing, I let off the gas and back on and the car bucked pretty bad. All the way home it has issues when I pressed on the gas but did fine at cruising speed. I would think a fuel filter would have been a slow progression issue so I am thinking maybe it is a sensor. I sprayed carb cleaner around vacuum hoses today and did not notice any surge so I think I eliminated a vacuum issue.

Prius (2010-12) :: Vibration At Mid-Throttle When In Slight Acceleration
My 2010 Prius with 140000km has developed a vibration noticeable anywhere from 50-80 km/hr when in slight acceleration (just over 1/2 on the green bars) with the ICE running. Dropping the throttle or hard acceleration makes it disappear completely - which tells me it's driveline related. It feels like its coming from the passenger side, particularly rear, but it's definitely getting worse and I can now feel it in the driver's door panel so it's becoming a major concern.
My first thought (due to the location) was a bad muffler but it's not any louder. I'm starting to worry it may be a transaxle bearing. I can't see it being a cv joint as there's no noises when cornering and everything underneath looked OK at a recent oil change. I love this car (what Prius owner doesn't?) and I sure can't afford to replace it. It's been babied since day one.
Prius (2010-12) :: Slight Thump At Speed Under 20
About a month ago, I noticed a slight 'thump thump' at speeds under 20 and started thinking either tire or wheel bearing. Turns didn't seem to change the sound/feel but it always smoothed out over 30 mph. I could not see anything visibly wrong with the tires other than the front pair needed to be replaced. Wear otherwise looked normal. But Monday night, I needed to pickup my laptop computer at work and my wife and her two dogs came along.
It was midnight when we left but for good measure, I felt around the tires and could feel nothing. Overcast, storms were predicted and were on the radar west of us. We walked the dogs; got the computer, and; Holly said she'd like a nightcap. So we went to a local bar and had a good time. Got back in the car, backed up less than 2 ft and 'poof' a cloud of white power flew from the passenger side, front tire:
As I was getting the tire off, a brief 'sprinkling' occurred...
Golf IV R32 :: CEL Blinking - Slight Hesitation Around 2500 Under Hard Acceleration
The problem started with a slight hesitation around 2500 under hard acceleration. Then it became more pronounced from 2 to 3.5k. The CEL would blink when it happened for more than a few seconds. Eventually the CEL stayed on. Now the car idles roughly with a periodic thump feeling, and any time a load is put on the engine, it feels very rough. I don't have VAG-COM, so I don't have any codes.
View 3 RepliesGolf/GTI VII :: Full Throttle Acceleration - Slight Hesitation As Revs Climb
My GTI is the first FWD car I've had since 1985, so the issue that I'm having may be just me adapting to a front drive platform. Here's what's happening: when I nail the throttle in 3rd or 4th gear, on or about 4K rpm or above, the car feels as if it's hesitating slightly as the revs climb.
It accelerates fiercely (I have the JB1, and I had the Neuspeed Power Module before it, and it's reacted the same way with each mod), and it's almost as if the front end of the car is lifting and struggling for traction (although the traction control light doesn't come on).
Is what I'm experiencing normal FWD behavior? Is it the beginning of torque steer? I only notice this at full throttle--not noticeable at all at partial throttle. Also, it doesn't happen consistently. My car is a performance package manual.
Ford F-150 (2004-2008) :: Engine Vibration / Miss At Idle - Slight Hesitation During Acceleration
I posted a while back about my 04 5.4 having an issue at idle. I did all the normal things like replace coil, spark plug, etc etc. No change to the issue. It still acts as though it's misfiring on a cylinder and I get codes P0306 and P0316. Finally took it to ford and had a diagnostic check ran. Everything on the top end was in working order. The tech even put a known working coil on 6 and nothing changed. I was told that it's either an intake or valve issue on that cylinder. But no definite answer to problem.
Fast forward to yesterday. I got a wild hair at lunch and went out and started truck. Pulled injector plug off of 6. No change to the way it was running. I did the same for 5, 7, 8, 1, and 2. All of which made a big difference in the way it ran. It was obviously misfiring with no fuel to cylinder. This gave me the idea to swap 5 and 6 when I got home to see if the issue followed the injector from 6. I did NOT. I pulled the plug on 5 and got the obvious change in the way it ran. So there is definitely something going on at cylinder 6 that I cannot figure out.
PCM, bad intake, bad valve? I'm not rich so a trip to ford for repair is gonna have to wait. Truck seems to run fine when driving except for slight hesitation during acceleration.

2003 F150 5.4 72852 miles
I have a Rough Idle & sometimes a hesitation or stumble on acceleration. I cleaned the MAF & IAC motor & Air & Fuel Filters are new. I got a 20890 scanner & ran test 6 53 as suggested in many posts by BlueGrass. Here are My results & what They Convert to.

I'm guessing the cop's are ok & probably need plugs? I was hoping to just swap a coil. Too cold to do plugs & truck won't fit in my garage.
Nissan - Altima :: 2010 - Slight Miss At 30 To 45 Mph Upon Acceleration
I purchased a 2010 2.5 Altima with 9K miles in 2011. After @ four months I noticed a slight miss at 30-45 mph upon acceleration. I told the dealership and they said it wasn't throwing a code. After two more visits I again complained about the miss. At this time the service person handed me a "Customer Satisfaction Bulletin" that explained that cars (Altimas, 2009- 2011 with my trans. and engine experience this "SURGE" as they called it AND that it is NORMAL.There is no way in hell that a auto maker would produce a car that does what my car does and consider it NORMAL. Buy the way, there is a "FIX" that was done but didn't work, that involved changing motor mounts and computer programming.
View 8 RepliesPrius (Gen 3) :: Slight Vibrations At Speed Of 15-20 Mph Or When Letting Off Accelerator
I have a 2010 prius with about 245k miles on it. I have recently noticed slight vibrations at speed of 15-20 mph and or when letting off the accelerator. I also noticed it goes away at higher speeds. I don't feel these vibrations when on battery or when coasting down a hill. I did an oil and filter change in March. I am planning on changing the spark plugs soon. What might cause a prius to jerk or vibrate?

98k miles and if the car is on a slight incline and your backing up or creeping forward it feels like you are going over a rumble strip. that slight stuttering feeling. no codes have tripped. I've asked the toyota dealership and they don't know what could be the problem. The trans axle fluid was changed at 88k and from what i was told there were no metal shavings in the fluid. it was a little dark but after going 88k miles i assume it would be.

View 3 RepliesHonda - Cr-v :: 1999 - Slight Constant Scraping Sound When Car Is In Motion
1999 CR-V with 70k miles. Just noticed a slight constant scraping sound when car is in motion. I had a friend drive the car in a tight circle around me while I stood in a parking lot and was able to isolate the sound to the front right wheel. Sounds like a caliper dragging on the brake disk. Brake pads have plenty of meat left on them. So far, these are the possible causes I can think of:
caliper piston sticking in bore
caliper not sliding freely on caliper pins
brake hose restriction not allowing piston to retract
I had never heard of a brake hose restriction not allowing a piston to retract, but I just read an online forum comment where someone was having a similar problem, and someone else said it was possible for an old brake hose to look fine on the outside but be swelled on the inside, thus restricting fluid flow. And can something like a stuck piston be remedied with grease, or does the whole caliper have to be replaced?
Prius (Gen 2) :: Slight Grating Noise When Loaded Up Left Front Wheel (by Steering Right) At Speed
I drove our 2007 Prius (79K miles) the other day and noticed a whirring or slight grating noise whenever I loaded up the left front wheel (by steering right) at speed. It's far from a hum or a howl at this point.
