Have an 04 Jetta GLS 1.8t manual. While accelerating at lower rpm and I'm kind of on the gas to get up and go it starts bogging out. Could almost describe it as a little jerky. Anything over 3000 rpm there's no issue. Doesn't matter what gear I'm in either.
View 15 RepliesBeen having an issue with my 01 Wolfsburg VW Jetta 1.8T.
Whenever I'm accelerating (most noticeable in lower gears), it seems like the turbo can't keep up. Used to sound like a nice clean consistent whooooosh spooling up, but now its more like brrrr......brrrrr......brrrrr.....
Don't know how else to describe it. Seems to start and stop frequently. Will try getting a video clip of this tomorrow.
I have a 2004 Nissan Xterra that has been chugging for a few months now. The problem is intermittent and only happens about once or twice a week when driving, but when it starts to chug (feels like it is running out of gas, jerky, will not accelerate) it is unsafe to drive on the freeway. I have taken it to several places and no one can figure out the problem. It was pulling two codes the speed sensor on the transmission PO500 - and the knock sensor code was coming up along with that. I had the speed sensor replaced twice and checked the wiring. We replaced the fuel filter, checked the fuel pump with a fuel gage and fuel lines, replaced the distributor cap and rotor, put in a new MAF sensor and still nothing is working to remedy the chugging. My last stop is replacing the knock sensor for $600, the problem is that the Nissan Mechanics (I visited two dealerships in different cities) told me not to replace this as it would not cause chugging. Several other mechanics around town tell me that they are wrong and I do need to replace it.
View 13 RepliesMy 2011 Golf R is tuned to Stage 2+ by Revo and has the following hardware modifications:
1. Miltek turbo-back exhaust
2. Larger Intercooler supplied by Revo
3. Autech (spelling??) HPFP
4. Revo intake system with a foam filter
Lately I have experienced the following problems:
1. Difficulty in starting (sometimes)
2. A kind of "flutter" on starting as engine revs settle to the idle level
3. A noticeable hesitation in taking off from stand-still
4. Jerky acceleration immediately after the car moves from stand-still
5. At any speed, a noticeable hesitation when throttle is applied
All the above issues have happened in normal driving. By that I mean NOT hard driving. I drive my car on DSG "manual" shift mode.
Unfortunately customer service from, both, Revo and the VW dealer in Dubai leaves a lot to be desired. What are the different possible causes of the above problems, I can make sure that Revo / VW go through the full list until the cause(s) are identified.
I just bought a 2004 Jetta and noticed the bottom of the engine does not have a lower belt guard... I can just see the serp belt spinning. I feel like there should be some kinda guard to protect it from Weather and debri? It's a 1.8T.
View 4 RepliesGot an odd clunk, feels like rear off throttle from hard acceleration. Feels like diff bushings might be worn. Looking for some info about diff bushings and how they feel. Also found the front prop shaft coupler looks like its seen much better days so ill be replacing that.
View 8 RepliesWhen I first start me car up, doesn't matter the outdoor temperature it idles terrible jumping up and down. When I go to put it in first gear and attempt to pull out it's very jumpy/jerky because of this rough idle. Once I drive a little bit if I stop it will idle fine. This problem seems be slightly worse when it's wet/raining/humid.
Its throwing codes P1128 Manf Control p0300 multiple misfires and then p0301,0302,0303,0304 which is misfire for that individual cylinder. Also my oil light blinks once in awhile, think that could possible be sep issue though.
I changed plugs, the old ones were really white... I believe that means running lean?
Put in new coil/wires
Gas Filter
Mass air flow sensor
Changed 02 sensors
Also did the seafoam treatment, none of it seemed to work...
Though about possibly changing temp sensor next. I hope it has nothing to do with fuel injectors....

So apparently even though the engine light is coming on and off it's not recording any error codes.I tried with my reader, one from Auto one, and then a better one at a local shop, none of them would show anything. The issue is it feels jerky when the light comes on(or goes off). Imagine cutting your cruise control off while it's accelerating and then immediately cutting it back on and that's similar to what it feels like. What could be the cause? I guess I might drive my wife to work tomorrow so I can go by the dealership in Atwater Ca (I'm a bit worried, the one in Yuma, AZ tried to rip me off for three grand).
View 5 RepliesI recently bought a 2004 XC90 T6. It has several issue and one strange issue is the sluggish performance: the vehicle sort of hesitates, requires quite a bit of acceleration effort to get up to speed, feels 'heavy', and in general does not seem to have the right amount of power. What makes the issue strange is that performance improves, noticeably, when the car is starting to run out of fuel, or when the "low fuel" light comes on. It is not a placebo effect: i've verified it several times that soon after the light is on, the vehicle becomes a lot more responsive, accelerates well, engine seems to sound quieter a little even.
I do not know much about cars. I am slowly learning after purchasing this vehicle. I verified that the air filter is clean. It has synthetic oil put in. I recently changed the spark plugs (very proud of that), that did not seem to improve the performance. My plan is to purchase and configure VIDA diagnostic tool and scan the vehicle while driving. It might also be worth mentioning that the vehicle is getting very poor mpg, averaging to 6 km per little.
One important note: the MAF sensor is faulty: i drive with it being unplugged, however when it is plugged in i experience the same as described above. I know it is faulty because when it is plugged in and the car is started up, the RPM goes to 2000+ and there for up to a minute or longer. If the MAF is unplugged this does not happen.
weird thing happens in my 2.0 manual jetta. every 1500ish miles, when coming to a stop, it feels like my car is about to stall but its not in gear.The trip milage will reset, radio will turn off, dash will dim, but no CEL. Since then key fob doesnt work (replaced fob batteries), and my DRL are off. still cold starts no problem (figure its not the battery), trying to figure out if i can get closer to what needs a fix before tearing into something unrelated.
View 3 RepliesI get some bucking under load between 1500 and 3000 rpm. This issue is more noticeable when the engine is warm. When it does this it makes a sound that to me sounds like a misfire from the exhaust, but I've never gotten a misfire code.
Sometimes i get codes p0411 and p0420 (secondary air injection and cat efficiency) but VCDS tests say my cat and o2 sensors are all good.
What could be the issue at hand here. I just recently bought a 337 edition gti and I absolutely love it. But the guy I bought it from says that it was chipped but he doesn't know what brand tune it is. But the problem, like the title suggests, is that in first gear the car pulls incredibly hard but as soon as I shift into second I lose all my momentum and it just feels sluggish.everyone that I've seen on these threads have said that I should be getting the most power I'm second and third gear. Is this tune just not a good one? Could there be something more?
View 4 RepliesI changed my oem clutch in my mk4 golf 2.0l with a stage 1 ecs tuning clutch kit. Lightweight flywheel, clutch disk, pressure plate and throw out bearing. But since I have my clutch pedal has been less stiff then usual. I like my clutch pedal as stiff as possible but it just isn't I bled off the slave cylinder. When I was done no air was coming out but it is still way to soft for me. What should I do next??
View 6 RepliesSometimes, when I get on the gas rather hard, my acceleration is sort of stuttery and jerky. It's not a traction issue, and I just got Unitronic stage 1...but I was having this issue before that.
View 1 RepliesIt's been over 100*F recently, and we just started running our AC on BLAST (Auto, 74*), and my perfect Prius has been giving me acceleration issues... When it's in PWR mode (100% of the time) and the AC is full blast, and I punch it, the car hesitates, jerks forwards, hesitates, jerks again, then eventually once it's over 15-20 mph it smooths out and goes.
Just to add to the chaos, for the first time ever in my life, I actually HEARD the fan from the vent for the battery. It was pushing air out after I parked the car. Never heard that before, ever! I just want my Prius to be as perfect as it's always been... BTW, I pretty much drive the heck outta that thing. I like how it goes around corners and the acceleration in PWR mode.

I notice that under normal acceleration, my cars transmission shifts very jerky. I understand this can happen if your driving stick but I have a TIP. Is there anyway smooth or eliminate the jerks?
View 2 RepliesI have a 1998 Ford Ranger. My problem is jerky application of acceleration. I note slack in the cable connecting the pedal to the engine throttle. Is there any way to adjust this cable length to remove the slack.
View 5 RepliesAfter a road trip (approximately) 80km both ways, I came back to my home area and filled up and got a car wash. Then I went home. About 2 hours after I noticed the car felt very jerky, and had no acceleration. Then big time sputtering. I turned off the car and waited for it to cool down. Once cool, it just kept on cranking. It started at one point and the engine light came on. And now it only cranks.
View 3 RepliesI get jerky acceleration at low RPM (around 1200). It feels as the engine cuts off fuel for a blink of an eye and it does that 1-3 times. It doesn't happen when the engine is cold. It starts after cold engine warning light turns off.
Year 2000 .... Engine 1.3 vvti .... Automatic transmission .... 140k kms ....
It's come to my attention that I have a thumping sound coming from my lower front end. It only happens on low rpm's and I can hear it best when it's in neutral, if I give the brakes a little push I can hear it louder, more profound, and can also feel it on my feet a little, but I don't only hear it while I have the pedal depressed. So..what it could be?
View 1 RepliesSo the car is a 1999 golf gti with a 2.0 AEG with a 5 speed manual. My brothers car. He has been telling me its been hard starting in the mornings for a couple months, sometimes it dies, sometimes it idles at 500 or lower, he has to rev it up to 1500 to get it to warm up then in kinda stays normal till he cold starts the car again, then does it all over. So he was driving down to my house to leave it with me to look at and on the way over he heres a big bang. has the car towed over here.
Cyl #3 has backed itself out and clearly a serious misfire, threads look fine so I put all new plugs in oem ngk three prong, runs ok still too low 400/600 stalling a couple times. this morning i installed new wires (Bosch)and a coil (aftermarket) and it barely wants to run now, stalled instantly. So I put the old coil back in and it stays running but watching the motor, its clearly misfiring. No codes as of yet and i have no access to vagcom. I've checked the firing order and wire placement on coil like 8 times to make sure it is correct.
