Golf IV R32 :: Hard Acceleration In 3rd Gear / Momentary Loss In Power

Having problems where sometimes the car won't go into gear, other times it's fine? The problem started after some hard acceleration in 3rd, there was what felt like a momentary loss in power. I dipped the clutch as I thought a boost pipe had popped off, all was fine (still seeing boost when revved). After this it got progressively harder to get gears, finally resulting in not being able to get into gear at all.

I found I could get it into 1st with the engine off and could go up gears normally, but couldn't change down without stopping and turning the engine off. The clutch is working fine, the biting point is normal. The problem seams to come and go randomly, it will work fine for a while and then start playing up again. When working the gearbox feels normal, there is no grinding or wining noises. I can move between gears normally and do clutch less gear changes.

There is now a vibration which can be felt at 1000rpm when stationary. It feels like it coming from the engine/gearbox and seems like something is out of balance as it shakes the whole car. The car is on 91k, supercharged running 470hp & 370lb/ft (at flywheel) and is fitted with a Spec stage 3+ clutch and solid flywheel.

Chrysler - Towncountry :: 2006 - Hard Starts And Loss Of Power On Acceleration

I have a 2006 town and country with a 3.3 and 220,000 miles.

Last week I was having some hard starts and loss of power on acceleration. My check engine light flashed during one episode so I had autozone check the code and it showed a misfire. I changed out my plugs and wires and that solved my issue. It started and ran like new.

Yesterday, I was running errands and my charging light came on. I was about ten miles from home and I decided to go for it. It was night so the headlights were on. Along the way, everything started to dim. Headlights, dash lights, airbag indicator came on and then the van just died. I walked the final mile and we towed it home.

The alternator and battery were both replaced last year in November making them both one year old. AC Delco battery 660 cca and I had a very reputable alternator shop rebuild the alternator.

So before I towed the van home, I hooked up some heavy duty jumper cables from a running chevy venture and let it charge 15 minutes. After the 15 minutes it was just clicks in rapid succession.

I hooked it up to a trickle charger overnight, 12v 2 amp setting. This morning, the van started, idled fine for about five seconds and then started trying to cut out. I kept it running by giving it gas but after about twenty seconds it stalled. I tried to restart and nothing but the rapid clicks. Three more hours on the trickle charger and the same exact thing happened. It started, began to stall, quit and then wouldn't restart.

I noticed today that the power steering reservoir was leaking a decent amount of fluid down onto everything around it including the coil pack. I replaced this today and used brake cleaner to clean all the surrounding components.

After doing some internet sleuthing, I found a thread with the same problem. For this guy, he had a disconnected ground from the negative battery terminal. I chased mine down (G101) disconnected and wire brushed it all clean. Put it all back together and still the same problem.

Here is what I have discovered:

Trying to jump it from another vehicle only results in the clicks. This is true whether the jumper cables on the dead battery are on both terminals or the negative is grounded on the motor. If the battery were the problem, I should be able to jump through it. If the alternator were the problem, I should be able to start with a jump.

After charging the battery, it will start once but then die soon after. Battery with the key off will read just under 12 volts (11.9, 11.6). With the key on, it will drop to the 8's (8.6, etc.) I have not yet had the battery or alternator bench tested. I plan to start with the battery in the morning.

It seems to me that the alternator wasn't charging the battery or it wouldn't have just killed the battery as those accessories should be powered by the alternator. It shouldn't be a starter issue since it will start after being on the trickle charger.

Ford 7.3L Power Stroke (1999-2003) :: 2007 - Acceleration And Power Loss?

I own a 2000 7.3 6 speed with 175,000 miles. I just bought it less than a month ago and it is my first diesel.

About a week ago I stepped on the gas and it just had nothing. I have a TS 6 position chip that I unplugged as soon as I noticed the loss in power. When I first bought the truck it was incredibly fast and now it has nothing to it at all. I have to have it higher in the RPM's to go up hills (especially when its not warmed up). If I push the pedal down it will sound the same, boost will get to about 14 (without chip) and the truck doesn't let out any smoke but it just doesnt have any power at all. I recently towed another vehicle on a trailer and it really struggled with it, more than I thought a diesel should.

When the chip was in, the truck would let out black smoke even after I noticed the loss in power. That made me think that the engine was getting enough fuel. I thought there could be a boost leak somewhere but it still builds 14 psi. However, I do not feel boost kick in at all! When I first got the truck it would only build around 14-15 stock but it felt a hell of a lot faster and I could feel when boost would really kick in. I took off my intake and looked at the turbo and the fins are in great shape and there is little to no play.

What the problem could be? I don't have very much money to start dumping parts into the truck and Im not sure what to do. I guess my questions would be:

1) Is it a boost leak, fuel problem, or something else?

2) Could a gelled filter give me these problems?

3) What should I do and where should I start?

Gmc - Jimmy :: Sluggish Acceleration From Stopped Position

I recently took my truck to the mechanic for a bad transmission leak, they told me they had to replace the Oil Cooler Lines (upper and lower) and that they did a transmission service (flushed out the transmission), the leak is fixed, but as soon as I started driving, I noticed that the acceleration is very sluggish from a full stop, I can floor the pedal and there is no difference, once I get going it seems fine (though a bit high on RPM's but not much). I also noticed some of that liquid sealant residue droplets on my windshield, similar to the type of sealant an AC place did for me to seal an AC leak, not sure if that has anything to do with this.

Ford 7.3L Power Stroke (1999-2003) :: Loss Of Power During Acceleration

A little background first on my 1999 Ford F350 7.3. A few months ago I noticed i had fuel in my coolant which lead me to a cracked injector cup. I replaced all 8 cups and since I had it apart, and I bought the truck used and didn't know what had been serviced, I replaced the injector o-rings, glow plugs, valve cover gaskets, and valve cover gasket wiring harnesses. Got it all back together and had been running great.

About a week ago I was parked with engine running and the stereo suddenly turned off. A few minutes later I turned the truck off and turned it back on about 10 minutes later and it wouldn't start. Batteries appeared dead so I jumped it and made it home. Took both batteries down to AutoZone and since they were under warranty got two new ones. Figured out my alternator was bad and not charging my batteries so I ordered a new one.

Up to this point truck has been running fine. Truck had sat in my driveway for the week while waiting for the alternator. While I was out of town my father in law went to use the truck and noticed it wouldn't start. He hooked some jumper cables up and got the truck started. He said as he drove off the truck had no power and smoke was pouring out the exhaust.

I charged the batteries and installed the new alternator. Truck starts great and seems to be idling normal. When I took it for a test drive it has no power when accelerating and black smoke pours out the exhaust. The truck will barely make it up any type of incline.

I thought maybe it was the injectors not firing. Wiring harnesses are plugged in and do not appear to be damaged. I did not remove the valve covers yet as it's not difficult but time consuming and I figured since I just replaced all of it that it should be ok. I did a buzz test and all injectors passed. I get no trouble codes or check engine light.

Ford 6.0L Power Stroke Diesel :: 2003 - Loss Of Power - No Boost On Acceleration - Vibrates?

I have an 03 6.0 Power stroke. My problem all started the other day when I started to occasionally not get any boost on acceleration and lose of power and a lot of vibration like it's about to cut out but it got worse now today I drove it about 5 miles into town when I got to town I noticed a rough idle I got gas in a gas can not in the truck. I got back in to leave and I had absolutely no power at all the truck stalled out and it was very hard to start finally got it started and it runs really rough almost like it's going to shut off.

So when I started driving I would only make it about a mile or so with out it chocking out and having to let it site for a minute or two and start it back up and go another mile or 2 and have it do the same thing all the way home all the time I have vary little boost if any at all except for when I first pull out now oil pressure is good and engine never over heated some of the codes I have is an EGR code and a contribution balance code for several cylinders I was thinking possibly a maf sensor or a clogged egr not working right.

Touareg :: Loss Of Power Upon Acceleration

Occasionally I experience a temporary loss of power when I try to accelerate. I press on the accelerator and nothing happens -- then finally catches a second or two later. Usually it happens at lower speeds as when turning a corner in town or when climbing a hill.

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?

Accent LC (2000-05) :: 2002 - Hesitation Under Hard Acceleration On Lower RPM

I have a 2002 Hyundai Accent with a 1.5L SOHC and manual transmission, with 207,000 trouble-free miles on it.

I have recently noticed a hesitation under acceleration. It happens most frequently under hard acceleration under lower RPM, if I'm close to lugging the engine. The engine "hiccups," almost like it is missing a cylinder. It will hiccup 2-3 times until engine RPM's increase, then smooths out.

What the cause may be? Last changes: Plugs at 175K; Plug wires @ 160K, Fuel filter @ 100K, Timing belts at 60K, 120K, 182k. K&N air filter cleaned at 50K intervals, last time @ 200K.

Golf IV / Jetta IV :: GLI 1.8t - Loss Of Power / Misfire Under Acceleration

I have a 04.5 GLI 1.8t, performance mods include, cone filter on the end of my maf, silicone TIP, Forge splitter, 3in custom tbe and unitronics stage 2

I started noticing this problem on the day I got the car tuned, I hadn't noticed it before hand. I replaced the spark plugs and it worked a little, but it continues to do it.

The problem: When I get on it at WOT under full boost, around 2500 rpms, the car loses all torque, misfires spits and sputters throughout the rpm range until about 5300 rpms then it all of a sudden has torque and pulls great.

I don't have any boost leaks that I know of along with vaccum leaks. There is no flashing cel or misfire code for my coil packs. Can this be a faulty n75 valve? if so what could fix it?

Mazda - Protege :: 1995 ES - Loss Of Power During Acceleration

I am the original owner of the car, which has approximately 125k miles on it. The car has given me great service, but lately a strange problem arose that has my mechanic stumped. When I try to accelerate, the car typically does not respond. After 5 seconds or so, the engine suddenly comes to life and the car begins to accelerate. At high speeds it is not an issue, but the engine sputters once in a while. It has never stalled. It is not the transmission because the RPM stays low during low-power times.

The mechanic initially thought that it was a dirty fuel filter. But, changing it has not worked. Once the engine light came on, and the code was for the air-flow sensor. But, the mechanic is not convinced about that.

The problem tends to become worse after driving for a while, after the engine has warmed up.

Ford 7.3L Power Stroke (1999-2003) :: 2001 F350 - Power Loss / Hard To Hold The Speed?

I drive a new to me 2005 F350, he has a 2001 F350. While we were talking he said he didn't think his pickup had the power it should have. He pulls a 5th wheel camper that weighs around 8000 pounds fully loaded. He said it takes a couple of miles to get to 55 mph, and it is hard to hold the speed. It doesn't have the power it did when he first got it last year. He was told that a diesel is slow getting started. He rode with me in mine, when I dropped it about half throttle to pass a slow car he said he could tell mine had way more power.

His check engine light is not on, it starts good both when hot and when cold. It runs smooth, no miss as far as I can tell listening to it. What are some common issues that could cause this? He did just change the oil and fuel filters, not sure about the air filter. He said the power loss came before he serviced the engine, and did not improve after the fuel filter change. Where to start? He was also told to check the filter inside of his fuel tank, so he is getting ready to drop his tank.

Lexus LS 2007+ :: Loss Of Power On Acceleration - 2009 LS460

2009 LS460 I have had my car at the dealer a few times for loss of power on acceleration. The last visit which lasted three weeks finally gave a diagnoses. The problem was confirmed by the dealer and the factory reps, a knock sensor picks up a signal that retards the timing resulting in no power, I was nearly run over by a semi the last time it happened. They tried to give me my car back on 7/24/14 with the knowledge that the problem is not fixable at this time but I should drive the car and they will tell me when there is a fix. I left the car at the dealer. I was also told that they had a few others with the same problem that could not be fixed.

Mercury - Mountaineer :: 1999 V8 Power Loss / Backfire Under Acceleration

I have a 1999 Mercury Mountaineer 5.0L V8. It just recently began acting up. After warming up the engine goes through heavy power loss and inability to climb ANY hill. Usually cannot get above 30-35. I just recently replaced plugs and wires for a tune up and a faulty coil pack (approximately 5-6 weeks ago) causing a misfire on 8. Today in troubleshooting I attempted the "Backyard Mechanic" trick of unplugging the MAF sensor and took it down the road, no change at all in acceleration issues or on idle, truck runs the same. Unable to spot any exhaust or vacuum leaks or issues, recently cleaned MAF housing and changed Air Filter as well. All of these issues arose after a heavy ice storm, do not know if this had any impact or was just bad timing.

Accent RB (2012+) :: Noticeable Power Loss After Some Initial Acceleration

Bought my first Hyundai, a 2013 Accent last Saturday. Love almost everything about the vehicle.

It is equipped with the EcoBoost which I can turn on and off.

Noticing when I accelerate almost every time there is some initial acceleration and then a noticeable power loss. It's much worse when I'm accelerating through a turn.

Honestly it's hard to tell too much of a difference with the EcoBoost and AC off.

Also noticing the car really surges at times with the cruise control on. Obviously if I hit an incline it's going to boost a bit, but sometimes even on very minor inclines or straightaways the RPMS just fluctuate more than they seem to need to.

Wondering if this is normal for this engine and something I need to get used to. Coming from a Honda Civic I didn't experience this consistent power loss / fluctuation.

Tiguan :: Sudden Loss Of Power Right After First Acceleration When Engine Started

Lately having the following issues with my Tig.

When starting up the engine on cold start (or after having the car sit for about 30 minutes) after about 10 - 20 seconds; pretty much right after first acceleration the car all of a sudden looses all power. RPM fall down even when accelerating. Accelerating more only let's the engine stall more.

5-10 seconds later the engine functions normal again.... What problem could that be ?

Golf/GTI VII :: At RMPs (1000 - 2000) Hard Acceleration And Vibration In Steering Wheel?

But I have noticed over the past week of driving, whenever the RPMs are around 1000-2000, it is very hard for me to pick up speed, and I can feel a little bit of a rumble/vibration through the steering wheel. So...

If I feather the gas, the RPM increases slightly and you can hear/feel the engine rumble/vibrate. The speed doesn't really increase...

If I hit the gas more than 1/2 way down, turbo kicks in and the car shoots forward.

Is this normal? I find it very hard to add a little bit of acceleration if I feather it, the engine seems to be resisting it, if I hit it any harder, the turbo kicks in around 2500 RPMs. It almost feels as if it is in too high of a gear and the engine has a hard time accelerating a little bit...This is around ~40-60KM/hr
