Passat (B5) :: Loss Of Power When Accelerating - Car Hesitates And Takes Long To Switch Gears
I have the light engine on - and my mechanic has informed me that the O2 sensor on bank one needs to be replaced. I need to understand if the lost of power when accelerating the car can be directly related to the O2 sensor or something else. The car hesitates and takes long to switch gears on my Auto tectronic trany.

I have a 1999 Passat 1.8t manual transmission... My car shakes like it's going to stall and sometimes actually stalls when I come near to a complete stop. The car drives really bad... it jerks when downshifting and on accelerating... The performance of the car is crap. also When i put the car into neutral and coast to a stop, the revs will bounce up and down. I posted a couple months ago about this problem and I was told to clean the throttle body. I then cleaned my throttle body and replaced the gasket. This problem went away for about 5 days and then was back again. This problem is the worse when I go to school, which is when it's about 45 degrees outside.

When I'm driving, steady mph, my car feels as if I've just downshifted, or that my foot slipped off the gas pedal. When this happens I've noticed that the tachometer drops down from say 20 - 30 to 10 or less! But just momentarily. It happens to a warm or cold engine. It's going to give me a whiplash! I've brought it to my VW dealer. They put it on the computer, and no problem comes up! No lights on my dashboard are on either. This problem is really annoying.

My issue can be while driving with cruise on, or accelerating, the truck just losses power, then recovers. At idle, the rpm can, but not always, fluctuate.
There is no "misfire" when it happens, but it just falls on its face. I have NO diagnostic tools, and my injectors are not stock, so I am unable to unplug my DP.
My thoughts are to unplug the ICP and give that a shot? Meanwhile, I will put in a order for a elm327
Ford 6.0L Power Stroke Diesel :: Loss Of Power When Accelerating
It's a 2006 Ford F250 6.0 diesel with 307,000 miles on it. Up until a week ago it ran great but when I was in a drive thru I turned it off (to order) then turned it back on to pull up but the idle was very rough and the truck shook as I revved it up but it went back to normal after I saw a puff of white smoke. Ever since then every few stop lights I will begin to accelerate but there isn't any power and it shoots out a lot and I mean a lot of black smoke for a second then the turbo spools and it's normal.
Today though I turned a corner and began to accelerate after but I had no power at all it shot out an un manageable amount of black smoke mixed with very little white as I pressed the pedal. I put the pedal to the floor and the rpm were up to 2000 still no power I out it in tow hail still pedal to floor and now power! At this point I pulled over and called my dad figuring the truck wouldn't move anymore but I got no answer so I tried to go again seeing how ideas almost and and the truck worked fine small amount of lag but it ran made boost and worked until I got home. What could it be? I've heard maybe my turbo is bad maybe my egr valve but I'm just not sure.
Elantra XD (2001-06) :: Loss Of Power When First Accelerating
2001 Hyundai Elantra GLS ... I don't know what is going on with my car. When I start it, put it in gear and try to pull out, it feels like there is a loss of power. A few seconds later, the power returns . I can push my foot down, and the engine doesn't rev, but then it's like all of a sudden the engine realizes I have my foot down and takes off.

Mine is 2006 with 130k miles. Just replaced fuel filter, air filter, cleaned air flow sensor and cleaned the injectors. The car still feels slow and it seems to eat more fuel than before. The spark plugs and the wires seems to be ok. No warning or error on dash is displayed.
When push the accelerator it takes a while to respond starting from stop position, and when the car is moving and try go faster it feels like lazy so I have remove the feet of the pedal and push it again so it respond quickly.
Camry :: Power Loss On 2003 XLE / Not Accelerating Or Going Up Hills
My 2.4L 03 XLE with 220k on it is losing power. Running fine other than not accelerating or going up hills as well as it was last week. I have P420 cat code for the past 40K. It also has the typical smoky start from leaking valve seals and uses about a quart every 1k miles.
Ran a can of 44k through it and I'm about to pull the plugs and see what shape they are in, but I'm wondering if this loss of power might be the cat. I've been searching and it seems a plugged cat is a common cause for power loss. Seems likely since I use so much oil.
Seen the DIY replacement and leaky seals Rockauto suggested replacement Eastern ECOIII as well as the Walker.

'01 Silverado with the 4.8, sitting at 160k right now. I'm starting to notice a loss of power in the truck, when pulling out and accelerating it doesn't put you back in the seat like it used to and when going up a hill you have to force a downshift to not lose 15-20mph... it just seems like I'm pulling an invisible trailer back there. The fuel pump is about 1 year old, fuel filter less than 3 months, plugs and wires are about a year and a half old, PCV valve about 6 months old, fuel pressure regulator about a year old..

My wife has had her 2010 3.5 Santa Fe since new. Over the past year it's been having a clunk develop when accelerating, happening a few times from a start until highway speed. The clunks almost feel as if one is driving over bumps - that's what I thought at first. The power doesn't seem to be there anymore either. I have been driving her vehicle the past three years and it was fine when I first started driving it. But the past couple years I first noticed a problem and it seems it is getting progressively worse. My wife now notices it quite a bit too.
View 1 RepliesFord - Mustang :: Sudden Momentary Loss Of Power When Accelerating
It did this funny thing about 4-5 times over a span of about 24 hrs before dying and then won't start. It was like hitting the limit on a speed governed car.....sudden momentary loss of power..and it seemed to be when accelerating if that matters. The thing I'm sure of at this point is that the fuel pump is not coming on when the key is turned, I know that sound well, but also checked it at the external connector with a test light for thoroughness. I also found a blown fuse under the hood which coincided with a little smokey smell inside the car when the fuse was replaced and blew again.
There is no spark as well. My Haynes book says that the PCM is behind the passenger kick panel but I only see the eecv and it doesn't smell burnt. The IFS is good. There is power at the coil packs. Fuel pump relay fuse is good. Is it more likely the ccrm since it contains the fuel pump relay and PCM relay or could it still be the eecv? It feels like one part failed but is causing more than one "problem", no power to fuel pump and no spark.
Jeep - Grandcherokee :: 1994 - Complete Loss Of Power When Accelerating
1994 Grand Cherokee Laredo, 100,000 miles:
Driving out to see my BF this afternoon I noticed when I accelerated it hesitated a bit. I didn't think anything of it so I let it go. Driving home was another story. I was about 5 miles from home coming up to a red light and I started to brake, the light turned green and I hit the accelerator and I got no juice, I got across the highway and started to brake and the brakes locked up, the steering wheel locked up and then I lost all power. I got the Jeep to stop (right at the exit to a train station ) I tried to turn it back on and got no juice. I just got a new battery about 3 weeks ago. I called 911 since I was stuck in the middle of the road right outside the railroad station. Officer asked me to try to crank the engine again, asked if I had gas (have 1/2 tank) and then got me pushed into a spot until I can get a tow to my house in the morning.
The car has been fine, I never put "off" gas in, try not to let the gas get below half a tank.
Santa FE SM (2001-06) :: 2004 2.7L AWD - P0507 Code And Loss Of Power While Accelerating
When I bought the car a few weeks ago, there was a p0507 code for a high idle in park, about 1300 RPM, but sometimes shooting up to 3000 when I shifted into park and then dying down. The code goes on and off intermittently. Not that big of a deal at first. Then I started noticing that if I revved it in park it would take forever to die down to 1300, and sometimes would fluctuate around 2000. I also noticed hesitation while accelerating around 1500 RPM and the transmission hunting for gears while accelerating, as well. I noticed my throttle cable was very slack so I tightened that, and bought myself a throttle position sensor, thinking that might be the problem, but didn't install it yet.
I was driving on the freeway yesterday in cruise control and then I started losing power while my foot was on the gas. With my foot on the gas, the throttle would cut out every second. I was basically one second of throttle, one second of no throttle, all the way down the highway. Almost impossible to drive. This continued even after I turned cruise control off. I limped my way to Home Depot and installed my TPS in the parking lot, and drove most of the way home with no issues, although I still noticed a slight hesitation while accelerating. Alas, I tested cruise control again and then the throttle on/off problem started again, then I could barely drive the thing, even after cruise control was off again. I'll be returning the new TPS to Autozone today, since apparently that's not the problem. What's my next move?
Lexus LS 2007+ :: Loss Of Power - Hesitation When Accelerating After Turn Intermittently
I have owned this car for six months. The car now has 39K. The problem is getting worse.
Re: Lexus 2011 LS460 AWD
Subject: Hesitation / momentary loss of power when accelerating after turn.
When accelerating after a sharp turn with light to moderate acceleration, the car will have a momentary loss of power for about 1, 2, or even 3 seconds. This does not happen often, but perhaps once every two weeks and I cannot replicate the problem despite attempting to do so.
In all cases, I am talking about DRY pavement. It always happens after a sharp turn usually to the right. (Probably because most sharp turns are to the right actually it only happened once on a left turn that I will describe below.) Acceleration is light to moderate NOT hard acceleration.
In one case it caused a serious situation. I had just purchased gas and was entering a busy freeway. When accelerating, the engine had a total loss of power for a couple seconds as a large semi truck bore down on me with its air horns blaring.
I have a strong clue that may debug this problem. Once, when turning left, the car suffered a total loss of power. There was no traffic and I kept my foot lightly on the throttle. The car remained unresponsive. The engine did not stop, but it did not respond and remained this way for at least 5 seconds until I took my foot off the accelerator and then back on to the accelerator. During this period of suspended throttle, I noticed that on the right side of the dash an orange alert symbol was flashing I think it was a swerving car? I assume this indicated that the car was losing traction and the computer decided to cut power until traction was regained. But the pavement was dry, and the acceleration was normal. In no case did I ever sense that one of the wheels was slipping.
Chevrolet - Montecarlo :: Loss Of Power / Surge Or Lunge Forward When Accelerating
2002 Chevy Monte Carlo SS 6cyl 100,000 miles
Symptom, loss of horse power (from a stop and going uphill), surge or lunge forward when accelerating (misfire?), rough idle (occasional knock). Maintenance, regularly change all filters and fluids, recently had the m.a.f cleaned and changed air filter, spark plugs and wires, oil.
There have been times in the past year or so when the car would crank but not start. Especially when the car was hot. Wait a couple minutes and it would start. Also a couple of times the car would shake fairly hard when started, get up to speed and it was fine.
I have had people tell me anything from a clogged catalytic converter to bad fuel injectors or fuel pump.
Scanned the car last week. No codes showed up. Never had a Check Engine Light.
I forgot to mention that every once and a while the car will jerk when accelerating. I have a coworker who said his truck started to jerk forward and later would not start at all. Our mechanic said it was the fuel pump. I I will see what that does for him.
Ford :: 2007 - While Accelerating Loss Power And Shaking At Stop - Won't Fire Again?
I have a 2007 Ford Fusion 4.0L AWD. One day I went to pass a slower car and accelerated rapidly, but the car responded with loss of power and shook to a stop and would not re fire. I took it to the dealership and they said two cylinders were not firing and a fuse was blown. I looked on the internet and some people said their coils go bad or plug wires. I asked the dealership if that was the cause and they said absolutely not, but it's the ECM. They replaced the ECM and 2 days later my CEL came on and I took it back to the dealership and they told me my catalytic converter was bad and I could drive it until I had the money to replace it. Then a couple days go by and I was passing a tractor on the highway, I slowed down to 45 mph to make the pass and as I began to accelerated I felt a thunk, then about a mile later it started cutting out and shaking. This time it would re fire but idle rough. I tried on/off 3 or 4 times then it idled o.k. I then took it back to the dealership and this time they said it's all 6 coils.
View 7 RepliesChevrolet - Suburban :: 1994 - Slower When Accelerating Cold Or Warm / Power Loss
I have a 94 Chevy Suburban C1500 with a 5.7L, 350 Engine. It has 235,000 miles on it. I purchased it about 4 years ago with 191,000 miles in very good condition and obviously well maintained. I have continued to maintain it well.
For the past few months it has begun to start a little slower that before and when accelerating cold or warm there is a spot where it looses power. It doesn't sputter or die it just looses power. I can press the accelerator farther and it will come back to life and do fine. After a 20 -30 minute drive if I park for a while, 20 - 30 minutes, when I start it up it dies. The only way to keep it running is to give it the gas and smooth it out at about 1500 rpm for 10 - 15 seconds. Then I can drive it with no problem most of the time though it still has the dead spot on acceleration.
There is a good spray pattern from the throttle body injectors. Plugs and wires are relatively new and plugs look good (AC Delco Rapidfire Platinum). When I turn on the ignition without going to start, the fuel pump builds pressure for 4 - 6 seconds. I haven't checked the fuel pressure yet and am considering investing in the rig to do so. I recently replaced the fuel filter but that didn't work.
The check engine light has not come on but many of the lights in the cluster are burned out and I haven't felt like going to the trouble to fix that so it is possible that the check engine bulb is bad.
Yaris/Scion & Vitz :: 2000 Echo Hesitate While Accelerating Like Instant Loss Of Power
My car now has a little over 370,000 miles on her. The other day I noticed a hesitation while accelerating, like an instant loss of power/ jerk. It didn't do it much at first and the higher the RPM's the less it seemed to do this. Once I got the car up to 60/70 mph it was pretty much unnoticeable.
What it was. Thought maybe a vacuum leak. Nope. Maybe a bad TPS or CPS (didn't end up checking those), Thought maybe a bad injector or O2 sensor (didn't end up checking those either). I did try some fuel injector cleaner though but saw no change. I had a feeling it had to be a sensor or something because the motor itself runs great other than the intermittent misfire.
So I drive it in to work this morning. (1 hour drive each way) and aside from the minor hesitation/bucking/jerking while accelerating, everything went pretty smooth so long as I had the car up to highway speeds. So I get off from work and start driving home. The problem seemed to have disappeared completely for the first 3 or 4 miles, then all of a sudden it started up again. Only this time it had gotten much worse.
I could no longer get the car to go over 70mph and when I came to a stop the car sounded like it wanted to die (but never did). It took forever from a complete stop to get past all of the sputtering and hesitation/missing to get the car up to speed. It would keep cutting in and out (the motor bogging down, then gaining normal power for a second or two and so on and so forth). So I decide to take it to a shop to see if they can diagnose it.
The guy hooks up his code reader and looks at the car for a little bit out in the parking lot. All he could do was suggest to change the spark plugs and said that that was where he would start. So I went ahead and listened to what he said about the spark plugs (even though I knew there wasn't anything wrong with them because I had just changed them about a year ago). So I'm changing them out and when I take out cylinder 1's coilpack I notice it's wet. It seems somehow water or moisture had gotten down into there. So I dried everything off and changed the plug (the old one looked fine but I changed it anyway) and I went ahead and changed out all the rest of the plugs too (they all looked fine as well)
So after seeing the water around the #1 spark plug and coil pack, The injectors are right in front of there, so I decided to take the plug off the injector and take a look.
Sure enough, I took the plug off of the injector right in front of the #1 spark plug (far left spark plug) and wouldn't you know it, it had water down inside of it. I pulled the plug off of the injector next to it and it had water in it too (but not as much). How water could have gotten down in there but it did. I took a Q-tip and used it to dry up all the water down in there. Put everything back together and took it for a spin and everything was back to normal.
