Ford 7.3L Power Stroke (1999-2003) :: 2002 - No Acceleration / Truck Jolted Forward A Few Times?
My 2002 f350 7.3 was given to me in July of this past year. I was 15 at the time and I was told that it was hydrolocked. Funny enough this is where I came to learn how to fix it, and this is the first time I have had to ask a question . I pulled both heads and replaced all 8 injector cups, I also had the heads re surfaced and had 7 injectors rebuilt and 1 replaced. I got it on the road in February around the 20th and since then I have put about 300 miles on it. Today I stopped at a red light and made a left turn and as I went to accelerate the truck jolted forward a few times and it felt like a tire was going to fall off while accelerating(only to 30mph). I pulled into a driveway to check all the tires, then I turned around and my foot was hard to the floor and the truck wouldn't go over 15. Diddn't smoke when it first happened, but after getting it off of a flatbed I turned it around and it hardly had enough power to get up my driveway. And I noticed it was pushing a steady stream of white smoke, the oil is clean and the oil cap doesn't get blown off at idle when I set it upside down on the valve cover.

I have a 2002 Windstar . It had an issue with low RPM while idling so I've decided to clean the IAC valve and the throttle using a crc throttle body cleaner. I accidentally opened the TPS that clicked. I put it back together and since then I have slow acceleration (I literally press the pedal to the floor and nothing), hard shifting between 1 2 and 3, and it still has low RPM while idling (not as much compared to before tho).
I tried several positions of the TPS because I honestly thought that was the issue but it did not have any effect. At this point I am not sure what to do. I read some person online suggest that it could be a clogged EGR valve.
Accent LC (2000-05) :: 2002 Slow Acceleration / Seems Like Losing Power
I have a 2002 accent 1.6.(272,000 miles) It has been having this issue for awhile now. It is very slow to accelerate, seems like it is losing power. Also if I press the gas pedal hard it does not want to shift correctly unless i back off the gas pedal some and then it will shift fine. I have had the transmission checked and it has no issues (transmission has be replaced with only about 80,000 miles on it). Also if i try to run the AC it really looses power. It currently does not have any diag codes when I have it scanned. So far I have replaced spark plugs, ignition coil, fuel filter, and a diode that I was getting a code for. I am just curious if there is something that could be causing the issue that will not report a code.
View 5 RepliesPassat (B7) :: 2012 - Acceleration A Bit Slow On Takeoff
I recently picked up a 2012 Passat. I love it. Comfortable ride compared to my Volvo, looks amazing from the outside and, well, its a VW - always loved them.
So, my only question is about the acceleration. It tends to be a bit slow on takeoff. Its hard to explain, really, but it creeps a bit and then I find that I need to push relatively hard to get the RPMs up to get the car to accelerate. Ive never had this type of issue in a car before so I thought I would ask to see if this is normal. At first I thought it was maybe a gas saving feature. When I use Sport Mode or Sports Shift it accelerates fine with no issue.
Passat (B6) :: Slow Or No Acceleration - Camshaft Replacement?
My 07 2.0T wagon is in the shop for a warranty replacement of the camshaft due to warn lobes, resulting in no acceleration when mashing the gas. Anyway, car is in until the middle of next week while we await parts. While in there, they are getting me for the 40K service minus the oil change, as it was just done. Service tech says he has seen about 8 so far with the same issue just here in town...

I have a 2007 Passat wagon 4 motion V6 and what the problem is I am getting a rough shift between 3-4 gear sometimes, usually on a slow acceleration. I have had the valve body replaced which worked for a couple of months until the problem returned. I then had the transmission replaced which worked a little but the rough shifting is still present at times. The car still has warranty and not even the dealership knows what to do?

My 2002 1.8L 60K miles is making a loud woooshhh noise during hard acceleration. The noise seems to be coming from the engine, but it might be coming from under the car. I have a manual tranny, and this happens in all gears. There is no noise during idle, and no noise during mild acceleration.
View 3 RepliesPassat (B6) :: A/C Slow To Blow Cool Air At Slow Speed Or Come To A Stop
My wife's car is a 2006 2.0T Passat. It has been very slow to blow cool air on starting. Once you are moving at highway speeds it cools fine, but then blows hot air when you slow or come to a stop.
I have taken the car to a mechanic who purged and refilled the coolant. This did not fix the problem. Upon checking with the mechanic, we noticed that both the primary and aux. cooling fans start and stop at the same time, and only would come on when I would rev the engine up some (around 2000 rpm).
I have talked with this mechanic and one more. Both are certified master mechanics, but neither specializes in VW. They believe it may be the high pressure side switch or the compressor itself.
Buick - Parkavenue :: Acceleration Skipping At Different Times
My Buick Park Ave 2000 is having an acceleration problem. It seems to be skipping at different times. It happens more often at lower speeds than higher speeds. It still happens at higher speeds though. I was on a long trip of about 180 miles and on the highway it seemed fine. What do you think is causing this? I did take it to a garage and they couldn't find anything wrong with it and of course true to form nothing happened when they took it for a spin. They did computer checks and everything was fine.

The car seems to start accelerating on it own. Say cruise control is set you notice acceleration for no reason. Now cruise control does not work and acceleration at times still happens. It's not like you are flooring it just keeps going faster slowly. Don't know if this could be related I did replace the fuel pump recently and the crankshaft position sensor. I was looking to see if there is a re learn procedure for the crank sensor. I have replaced them in the past and don't remember having to do a relearn.

I have a 2004 grand prix gt, within the last couple of days, it seems to loose power on acceleration and the motor completely dies at times. After waiting 10 seconds or so it will crank but may die again or just feel like it is loping. The problem is getting worse quickly. I have replaced the fuel filter. This did not stop the problem. I thinking it may be the fuel pump. If it is the fuel pump is there any way to verify this to be sure it is the problem before replacing it?
View 3 RepliesPrius (Gen 2) :: Slow Acceleration When Speeding Up To Get On The Highway
I'm a new 2007 Prius owner, and I know that the Prius is no sports car, but this acceleration is very slow. When I'm speeding up to get on the highway, it really sounds like the gasoline engine is working hard to get up to that speed. I've had cars in the past where the emergency brake gets stuck, can that be a probable cause, or is this type of slow, strenuous acceleration normal for the little Prius?

It's a hot 110 degree day in my 08, we have 5 in the family. Parked for three hours and on return starts up normally. Noticed low torque and slow acceleration on take off. Got on the freeway and slowly got up to 65MPH with obviously only the ICE working.
View 1 RepliesElantra XD (2001-06) :: 2004 - Acceleration Is Slow
Girlfriend just bought a used Elantra. She told me about an issue shes been having with the car and how it feels as though its towing a trailer. I drove it for a day and noticed a few things. Vehicle has 110,000 miles
1. No CEL
2. Tranny seems to NOT be slipping (Revs climb just as slow as Speed)
3. Car feels VERY heavy at times. Especially on a start up-hill
4. No sputtering/misfires
5. Shifts up and down smooth
What I've tried so far:
1. Replaced Spark Plugs
2. Sea-Foam
3. Cleaned MAF/Checked Airfilter
4. Removed and Inspected BOTH Catalytic Converters and both seem to be intact. *plan on doing a back-pressure test as soon as I get the gauge from my buddy*
5. Checked timing marks
I put 1/4 can of seafoam in crank case and plan on letting it "run-in" for 25 miles or so. I plan on doing an oil change tonight as well as make sure the brakes are not hanging up (I should have checked this first, thinking back...but hind-sight is always 20/20 ) .
Santa Fe (CM - 2007-12) :: Slow Acceleration And Decreased MPG

View 6 RepliesTiguan :: 2010 - Slow Response - Lag In Acceleration
I have a 4motion Automatic Tiguan 2011. It always had a tiny acceleration lag which I believe is quite normal. But lately, our Tiguan developed a that-doesn't-sound-right symptom. I feel the acceleration gap is much longer now, the engine makes quite a bit of noise but the car hesitates to go, and it gets a bit worse on uphills. It had a transfer box leak that was fixed 3-4 months ago.
It sounds like a transmission problem to me. Is there something wrong with the power train?
Toyota - Prius :: Slow Acceleration / Gas Mileage Down
My 2010 Prius since new, during cold Central IL weather, when I pull out onto the city street, it accelerates VERY SLOWLY no matter how I work the accelerator for 1-2 blocks. Then it takes off normally. When I forget to allow the extra time, it can be scary to have a car coming up fast and not be able to accelerate. I have left it at the dealership for 3 overnights now over 3 years. They went from "couldn't duplicate" to "there is a slight hesitation" that they attribute to normal shift from electric to gasoline. The next morning it took 2 blocks before it kicked in. My gas mileage has only been 35 this winter; I don't believe it has ever been consistently that low.
