Lexus SC430 :: 2010 - Hesitation On Acceleration From A Stop

As I have experienced hesitation on acceleration from a stop, I found a TSB # L-SB-0154-10, that addresses this condition for the 2010 SC430. It was issued in 12/1/2010. I am not sure if it would apply to any other years. The TSB entails re-flashing he PCM with updated software.

Ford - Explorer :: 2002 - Hesitation / Jerkiness And Rough Acceleration After 1st Stop - Air Sound?

The problem starts after about 5-10 mins of start up and normal driving. First signs usually come leaving a stop light or stop sign. Hesitation, jerkiness, rough acceleration. It's usually slight, just enough to feel it. Soon it really shows up while keeping the truck at a steady speed, say 40 for example.

I finally heard what I would describe as a puffing air sound and figured vacuum leak.. finally! Nope.. it's coming from the rear underneath of the vehicle. I can't hear it in the engine, or the tail pipe.

2002 Ford Explorer xls 4.0 125k miles, I've replaced the air filter, egr valve, pcv valve, cleaned the maf and covered about every hose I can reach with carb cleaner checking for a vacuum leak. I've yet to try some of the other things due to hearing that puffing sound.

Passat (B5) :: Loss Of Power / Hesitation During Acceleration

My 2001 VW Passat 1.8T manual transmission is experiencing loss of power/hesitation during acceleration. Occasionally the check engine light will blink for about 10 seconds during this time. My valve cover gasket blew about 7 months ago. I had it replaced along with 2 ignition coils. Since then I have had replaced the other 2 coils and spark plugs because of this recurring problem. I have also replace the mass airflow sensor for the second time. The diagnostic check continually shows misfires in different cylinders for which I again tried replacing the coils. I have also received the codes for "fuel mixture too lean" as well as for too rich. What could be causing this?

Passat (B5) :: Hesitation When Accelerating From A Stop / At Half Throttle Car Bogs Down

I have a '99 passat 1.8t Tiptronic. 106,000 miles. Recently I've been getting a bad hesitation when accelerating from a stop. At half throttle the car kinda bogs down and hesitates then as the rpms get higher it seems to clear out and accelerate smoother. At the same time the car doesn't have the same sack it used to. I checked he plugs, found them very fouled. Replaced them and the problem got a little better, but definitely still there. There has to be a reason the plugs fouled. There is no CEL so I don't really know what to check first.

Passat (B6) :: Ticking Sound On Turns And Acceleration From Stop - Axle / Engine Mounts?

I noticed my 3.6L 4Motion is making a hard thump/ticking sound when the car accelerates from stop, and also on turns. I'm going to schedule service for the car next week and I wanted to get a little educated insight. This is strange because I just had two of my cats replaced last week.

It'll do okay when I am not flooring it, but when I do floor it there's a pretty noticeable lag and then VROM it'll take off like a bullet... This car has a manually operated throttle control, are there any adjustments I can make to make the truck more responsive? 2.4L 4Cyl....

Volvo :: 2014 XC90 - Hesitation And Very Little To No Acceleration

Have 2014 XC-90 w/10k miles. Problem is sporadic (has happened approx 10-15 times over past year).

From standing stop (stop light, etc) -- press on accelerator and VERY LITTLE to no acceleration. Engine continues to run smoothly -- no indication of fuel starvation, no roughness --- just no acceleration. It does NOT appear to be transmission oriented because when it finally "kicks in" there is no feeling of transmission shifting or wild tach movement (to indicate that there was a changing of the gears, etc). I get things back to "normal" by pumping the accelerator (usually a reflex action because the are vehicles behind me wanting to "go"). VERY disconcerting issue.

Local Volvo dealer says "cannot find any error messages", etc. My only complaint with the car -- second XC-90 and 5th Volvo.

Hyundai - Santafe :: Hesitation On Acceleration And Rpm Changes While Cruising

I have a 04 santa fe 2.4L 4cyl. I recently did an engine swap, old motor threw a connecting rod. I put my intake, exhaust manifold and head on it. Timed it. All new gaskets. Turn the key and it fires right up and runs great. But when you accelerate it sounds loud (almost diesel like) and doesn't shift at the right time, also while trying to cruise it will drop about 300 rpms and then come back up, then back down and up every 3 to 5 seconds. The transmission was fine when the old motor came out. The head/intake were fine also. All the vacuum lines are connected, cant hear a vacuum leak anywhere. But it keeps throwing a throttle body sensor code and it wasn't broken when the old motor went, i even swapped another used one on it and it still throws that code. I am thinking it has to be intake related.

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.
