I seem to loose almost all power once I hit 5k rpms. Like I will floor the car and Ill feel a nice pull and all of a sudden once I hit 5k it slowly starts climing like a hybrid civic. wtf? Could this be a misfire, tune problem, exhaust leak IDK
View 20 RepliesThe past couple days when driving to school in the morning i've been noticing that my car starts to rattle and struggles to accelerate once I pull out of my driveway. Once i get to the next stop sign to take off the car runs fine like nothing ever happened. My check engine light doesn't come on though. I usually let the car sit for about 30 seconds to a minute before i start to move the car. Mods I have are Unitronic stage 2, Forge 007p DV with yellow spring, and 3" downpipe.
View 1 RepliesI have a 2012 F-250 6.7L w/8K miles. I have been struggling with this issue for 6 mo. The engine feels like its missing at low RPM. I would equate it to the feeling of a bad coil pack in a gas engine. The boost indicator drops to 0 for a split second then recovers. The dealer says they can't find the issue but went ahead and replaced the turbo. After the turbo replacement It got worse. This is an intermittent problem with no codes.
View 14 RepliesWhen my 1989 Bronco II has about a quarter tank of gas left, it begins to "shudder" and lose about 500 rpms while I've got my foot on the gas. It will shudder and lose power for a second or two, then run fine for a minute or so, then do the shuddering stuff again. It'll do this all the way to the gas station. But with the tank full (or even half full) the shuddering stuff is gone as I drive out the gas station.
View 1 RepliesMy Legacy sedan is not behaving well. On more than one occasion, when pressing on the accelerator, the rpms do not rise. I put it in park and try to press gas pedal, nothing. Turn the car off and let rest for a few minutes, then start it up again, and it's fine.....
View 3 RepliesSo over the last few months I have been having more and more idling and power loss issues with my 2006 V6. When idling she intermittently will try to stall and the rpms will drop below 500 and then spike back up. A large percentage of the time I hear a loud whining sound while driving down the road and I notice that turning off the air conditioner will remove the sound at times.
***what I have done so far**
Idler Pulley
Belt tensioner
sepentine belt
cleaned MAF
Cleaned Throttle body
Throttle Position Sensor
Had car reprogrammed
So I pulled the belt off and checked all the pulleys and did notice some grittiness in the AC pulley (inner) and was wondering if this might be the issue. Attached is a video I uploaded, Video .....
So my 2005 elantra 2.0 CVVT has 189k on it 1 owner.
I got a check engine light one day and i read the code. Came out to be 02 sensor code bank 1. So i order a denso o2 sensor and replace the part.
I drive the car for about 400 miles to reset monitors and get a check engine light. P0420 cat code. At this point the car drives with normal power and pickup.
1000 miles later my car has lost power. It doesn't have any get up or power when driving normally. I take the car to my local shop and they recommend replacing front cat. I replace front cat, same issue.
At this point i'm not sure if it is a transmission problem or maybe my 2nd cat or something else?
On the freeway if I put my pedal to the ground the rpms surge up very very slowly,
Also seems like the car doesn't shift till around 4k rpms, seems like previously it shifted sooner.
I have an 05 corolla XRS. I just had a sport clutch put in about 1 year ago. Whenever I shift into 4th gear and accelerate, the RPMs drop about 500 and I lose power for about 3 seconds before it starts going back up. Other gears are acting normal. Best part is that I let my friend drive the car earlier and since he did it's been doing this.
View 7 Replies2002 ranger edge 3.0 5spd. Truck idles perfect, but when you get rolling and higer rpms feels like the engine is missing. loos of power and shakes. I replaced the usual, plugs and wire's, seemed to work for a bit but came back. I cannot get any info on the scanner and have checked all the fuses. I am thinking coil pack but don't understand why it idles perfect and only misses under acceleration. No check engine light on.
View 5 RepliesI have a 1998 Accord, 4-cylinder VTEC standard transmission, 226,000 miles. Last fall I first experienced a problem with the car where within 5-10 minutes of starting the engine and driving, the engine seems to lose power/fuel and RPMs act as if they'll drop low enough for the engine to stall. If I take my foot off the accelerator, and reapply, the engine seems to gain power again.
Also, if I open the accelerator to full while the problem is occurring, it can occasionally "push through" and gain power again. Similar things will happen while stopped. In neutral, RPMs fall low and suddenly jump back up and then settle into normal idle. The problem never persists longer than 10 minutes within starting the car.
I took my car into a local shop that came recommended by a friend. They investigated a "check engine" light that didn't explain the problem and were never able to recreate the condition themselves. They replaced a few parts but lost the work order so I don't even know what they changed, but the problem seemed to have solved itself for a while. Recently it started up again and I would love to sort it out.
I have a 2005 Honda Odyssey with about 190k miles on it. About a year ago (175k), we had our Transmission replaced with a re-manufactured transmission from the Honda Dealer. Now almost a year later, we were driving home on the freeway (about 4 hrs of highway driving) when we smelled and saw smoke coming from our hood. No lights or indicators came on. We also started losing power and the RPMs were high.
We pulled over in a gas station and popped the hood. A guy who said he was a mechanic took a look and thought it was the radiator host leak...suggested we add water and limp the rest of the way home. We did this and had no issues for the remaining 40 minutes of driving. The next day we brought it to our normal mechanic (not a Honda dealer) and he said it was transmission fluid ...thought that the transmission fluid that was splattered all over our engine/hood/wheels.
When we took it to the honda dealer (since we were still under warranty for the Honda transmission), they looked at it, cleaned it up and ran tests. They are saying that other than being low 2 qts of Trans fluid, they don't see any leaks/problems with the transmission, even after test driving it. They are wondering if the transmission cap was not tight or left off, causing the fluid to overheat, etc (I'm sure it wasn't left off as we have been driving it for months since our last check up without issue).
They say they can't replace it under warranty unless they can confirm some issue in their diagnostic tests. How can we have 2 qts of transm fluid splatter all over our engine and there not be a problem they can diagnose? Did they not give it enough time (e.g 4 hr long distance drive) to heat up enough to replicate the problem? The question now is...is it safe to keep driving the van (after doing a transm flush) or are we just asking for trouble until the next episode? How can I convince the dealer that there is a problem and have the transmission replaced under warranty?
Truck sat for 1 1/2 years. Changed filter and put in 15 gallons of fuel. Had maybe 1/2 gallon old fuel in tank. MAYBE. Fixed fuel line because it wasnt getting fuel and it fired right up and idles great.
Truck has no acceleration over 2500 (or so) RPMs but idles fine. This is depending on how hard you push the pedal of course.
If you drive the truck normally like a grandmother it seems to be ok. As long as you dont need a passing gear or need to accelerate more than 1/4 pedal
If you try to push the pedal to get the next higher gear it will sometimes hit the gear fine. IF you floor the truck it will totally lose acceleration. Then the truck will run like crap even slow for a good while. But then it will clear up for the low end. Then you can drive it normally. Then when I think I can test the upper end I get the same thing again.
About 3 weeks ago I purchased my MK7 GTI SE w/ DSG. About a week ago, I started noticing a very slight rasp around 3.5k and up under heavy WOT. Note the sound was very subtle in the cabin and unsure what it sounded like outside. This past weekend, I started noticing a loss in power, especially after 2nd gear. A strange sound under throttle--almost sounds like a supercharger winding down (hollow with a slight whine)--when giving a good bit of gas around 2.5k and up occurs. At first I though it was road noise from my neighborhoods new roads since the sound only occurs on new roads, but realized that noise never occurred the first few weeks I had the car. No CEL.
I took it to the dealership on a rainy day, so they couldn't see the loss of power with the car breaking loose, but they didn't find anything. I'm bringing it back this Friday to see what they can find. I talked with one of the service guys today and they think it may be a drivetrain problem. Supposedly no loose hoses and is holding boost normally. Any leads to what it may be??
The car has 108k I bought it with 101k that being said I had no clue when the last tune up was or if the coils were replaced, now I did replace the transmission, transfer case and clutch since then I've noticed a loss of power and torque especially after 3-4k rpm car just seems to fall on its face, if I had to explain it I would say it feels like it went from being tuned to stock, I have no clue if the car had software or not. also some times I get a sputter or almost a hesitation from the rear, I have done the haldex service 2 weeks ago, It absolutely feels like the car isn't breathing right I don't hear the intake as much or cleanly I'm wondering if the intake manifold bushings are bad and could even cause this? doesn't seem to pull as much just from the start though I used to just drive normal and the car almost felt like it was pulling its self doesn't feel anywhere as quick.
View 16 RepliesSo I know turbos can be prone to heatsoak. Does the same type of deal apply to SCs?
I guess my question is; when on the track, the SC obviously gets hotter than hell. Subsequently, do you lose power due to the SC possibly "overheating"?
I just had my '12 GTI's 40,000 mile service done about 2 weeks ago. I put in a K&N air filter the day after the service. The only thing I noticed about the car after service was that I could smell coolant, they either spilled some or its burping some cause it was filled past the max fill line. Outside of that everything was copacetic until yesterday morning.
On my way to the gym with cruise control on ~74 mph on the highway I had sudden power loss, EPC light came on and power returned although felt reduced. When I left the gym it was off and I made it about a mile when under acceleration it hit at about 3k rpm, again sudden power loss and EPC light, power returned reduced. Drove about 5 miles to work and did a little googling with a million results.
When I left work to go home I made it about ten minutes into my drive before it happened. This time the CEL came on. I was able to drive home and back to work again this morning but I keep having power shutters followed by the EPC. I haven't had much time to dig into anything but I checked the connection of the coils and the intake connections with a flashlight at 4:30 this morning. Thinking it might be the MAF only because I recently installed the K&N and have read the oil can kill MAF's and I might stop to get a can of cleaner on my way home to try that route.
IF that doesn't work maybe I can get it on a Vag Com in the next couple days to get it sorted out.
Replaced my cam follower at 37,000 mi and performed an oil change. Follower was in good shape - all done at a local reputable tuning shop. Accelerating on the highway, above say 2500 rpm, loss in power.
Car feels dull under load. Called dealer for advice (I'm tight with the owner, the tuning shop was closed at this point) and said that I might have a fuel pump or cam shaft problem. Car was fine before service.
What it could be? Will obviously call the tuning shop on Monday, but wanted to vortex advice so I could be armed and ready!!!
Today i come here for a AC/Compressor trouble: The AC on my Jetta 2000 2.0 works very well, however it seems that the engine loses a lot of power when the AC is on (the acceleration becomes very slow), and at the moment of turn on the compressor, the engine revolutions down to 400 rpm for a couple of seconds (after back to normality, 800rpm on idle).
I know that the power loss on engine is "normal" with the AC, but in mi case, seems excessive, and the fuel consumption, when the AC is on is vey high too. I think that maybe the compressor is stuck, but I'm not sure about that.
As additional information, i scanned the engine codes an throws P0422 (related to oxygen sensor)
I bought a 2000 jetta gls vr6 5-speed. Only had the car about 4 weeks, already I am in, ball joints, struts, brakes, core leaks and my half shaft fell off at the transmission. Now, driveabilty issue.
Severe loss of power, sputtering bad. when i shift, the car revs a bit. installed new O2 sensor due to a rich code and a out of range code. Now the EPC light is on with an implausible brake switch signal. Replaced switch still comes back on. Still running like poop. Changed the plugs also about 1k back. I just ordered a MAF.
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?
Due to being low, and taking my splash guards off to put on my skid plate, in heavy rain, my belt I guess gets wet, slips and I lose power steering. I can hear it screech.
I didn't think that would be the case for snow, but sure enough after plowing through my driveway to go to work it was slipping screeching and loss of power.
