I'm planning to mention this to the dealer when I get my first oil change, but I've been wondering if this is normal for the 2.0T. When stopping at a red light for example and the car downshifts through 2nd and to 1st, it gets very choppy - almost jumpy as it comes to a stop. Seems like I really have to concentrate to make a perfectly smooth stop.
View 7 RepliesQuick description: every part of any acceleration in any gear is completely normal. My only problem is when I decelerate downhill in 1st gear to a stop I get a whining sound up front that is choppy and sounds like it is coming from the center of the car, like transmission, ???
I am at 85k and replaced my transmission oil and rear diff. w. Amsoil 75w90 at 60k miles.
Some of the old posts question why I would be engine braking in 1st gear. It is because I have to "coast" out of a 6 floor parking garage. I never noticed the trouble at all because I am usually coasting in 2nd gear or neutral, but someone in front of me was extremely slow so I stopped and went to 1st gear then heard the noise. Like I mentioned, it only happens downhill (not under load).
Sound = "rum rum rum rum..." decreasing with speed as the car comes to a stop.
It's not a CV or wheel bearing because it only does it in 1st..
When I accelerate from a stop, the car jumps, slows down, jumps again, etc... I do hear a noise when I accelerate rapidly on the highway, almost like a leak somewhere, but I'm not really sure.
View 3 RepliesNotice roughness/jumpiness in the transmission when slowing to a stop, or crawling along (like in a shopping center)? it's quite evident on my car, and perhaps i just have a problem that nobody else feels.
It's as if the tranny is downshifting when slowing to a stop, and I can really feel it...makes it difficult to come to a smooth stop. and then if I'm moving very very slowly in heavy traffic, it seems to be "wandering" between 1st & 2nd...something like that...and it's very jumpy. Not smooth at all.
I realize that Lexus may come up with some reprogramming for trannies (that happened on my '01 GS, and it made a big difference).
I brought my truck to ford because I thought I was having transmission issues, but they are telling me that my transmission is fine, that I need to replace my number 8 injector. None of these symptoms sound like injector issues:
-Shifting from park to reverse, takes a couple seconds to shift, then jumps.
-Coming to a very slow stop, truck is a little jumpy at around 2-3 mph
The R has 48K miles on it. The other day i realized after driving it, a choppy noise coming from almost directly under the spark plugs. As the car was cooling down while still on the noise stopped for a few seconds and then started again. Any clue of what this might be?
View 2 RepliesI picked up my first GTI about 3 months ago, a 2011 Autobahn with about 35,000 miles. I love the way it drives. I had been admiring them from a distance, and was finally able to pick one up. Unfortunately, I've run into a few issues. I'm pretty much a rookie when it comes to the inner workings of cars, but I'm eager to get into it more. My issue is below:
Over the last few weeks, the car has been consistently a little sluggish, and the acceleration has seemed a bit jumpy. I've only used premium gas, and I've been looking for simple things that might be the issue. I live in Houston, and I was wondering if maybe the extreme heat and humidity might be the reason behind the sluggish performance.
Yesterday, I decided I would clean the air intake filter. It has a K&N intake from the previous owner. After cleaning the filter and replacing it, the car wouldn't start. I may have put too much oil on the filter or the humidity may have just caused it to take longer to dry than the instructions on the cleaning kit recommend.
I called my bro-in-law who is the go-to car guy in our family. He recommended that I try starting the engine without the air filter and pull out the MAF sensor and check it out. When I took off the filter, the car started fine. I replaced the filter, then also pulled the MAF sensor to see if it needed to be cleaned. I found that the bottom of the MAF sensor was bent and slightly dented. I could also see a place where the sensor had scratched the bottom of the pipe.
This morning, the car is running a little smoother (better than before, but not as quick as I remember), but the check engine light has come one. Could the performance issues be due to the damage to the MAF sensor? With the check engine light, is that something that is automatically triggered by removing the MAF sensor? Or is there some other issue.
When 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....
2000 Jetta 2.0l 4cy AEGengine
Just bought my 2004 Jetta GLS from a dealership last week. 2.0 Engine. Has 140K miles on it. 2 hour drive from the dealership to home was cold and foggy but it ran fine. In town stop and go traffic in foggy conditions since last Thursday and it has run fine. Got a downpour this morning and all of a sudden it is running choppy and the CEL is flashing at me.
I have a 96 MK3 as well that would run badly in the rain until I changed out the Electronic Coil. Got so I would carry spares with me.
Is it the same fix for the MK4 2.0? I've also read about using epoxy or JB Weld to coat the coils and keep the water out. Does that work for the MK4 Ignition coil?
2010 passat, my DSG seems really jumpy lately. 2010, car has 36k on it. Any adjustments that can be made on the DSG? Car is still under warranty.
View 7 Replies2004 passat 1.8T with 190K miles. Very well taken care of drove great a few days ago and i did notice a few hiccups during acceleration from stop or just accelerating from say 30mph. Nothing major figured something in the spark system
Today I was driving and it got alot worse. If I use 3/4 throttle or more the acceleration is so choppy that the car wont go anywhere until I ease out of it. now the Check engine light started flashing when this happens. Only thing different about today is that its colder
From the search and my moderate knowledge of cars the possible culprits are (in no order):
fuel filter
spark system (coils, wires, plugs)
plugged cat converter
Ignition module?? (not coils)
MAF sensor
Vac line/s
Pcv valve
190K miles. She idles great no a single hiccup. I am thinking pcv valve and fuel filter?
When receiving or calling someone via bluetooth, they sound choppy on my end but they say I sound fine on their end. The music plays fine over bluetooth also. Have used 2 different phones and both do the same thing.
View 5 RepliesAndroid person myself but noticed on wife's iPhone 6s occasionally the audio via Bluetooth to the jbl system gets choppy . it basically keeps cutting on and off. She has to duly then disconnect Bluetooth on iPhone and then reconnect to remedy.
View 10 RepliesI am having a problem which I can't pin down what it is. When I am driving my 2001 Prius, only after a turn, it seems to get real jumpy and the check engine light will come on during this. I know this is when it comes on because I unplug the starter battery to reset it several times. I've had it put on a computer and it gave a long list of things it could be up to and including replacing the entire gas tank assembly.
I've changed out the gas cap which was one of the things on the list, and I have a charcoal canister I got from the junkyard, but it's a pain to change, so if I don't have to change it, I really would like to not have to if it could be something else. I also put the highest grade of gas in it.
My truck is for the most part fine, but it's doing some strange things and I'm wanting to get some opinions before I go and tow a trailer 300 miles next weekend.
Last weekend when I started my truck I had the CEL on for about a minute, then it went away. Not sure if it was an influencing factor, but it was sitting outside in the sun in 100 degree weather before I started it. Truck ran fine for the 300 mile trip home that day. Two days ago, I drove to my parents house. It ran fine the whole way there and as I pulled up into the driveway, the engine randomly got really choppy like it went down a couple cylinders or something. Not sure how to explain it. I pulled forward the last 50 feet or so I needed to drive with the engine chopping up, parked, unloaded the stuff I brought, and fired the truck back up to go home. It was running perfectly fine again and drove back home without an issue like nothing ever happened.
Is there any components I should be checking out on the truck before I make my next trip 4th of July weekend or just brush it off as being a fluke? Truck has 230k miles on it.
I have a '05 Accent GLS Hatchback. 5-speed, manual transmission with about 82 thousand miles on it. I bought the vehicle used about 2 years ago. Ever since I've had it, its been a little jumpy in first gear when going at very low speed. Especially during traffic jams, barely pressing on the gas will cause it to jump a little bit until you put the pedal down further. Lately its starting to do something similar when it 4th gear. When you push your foot on the pedal it jumps a little and does the same thing when you take the foot off the pedal. What may be the cause? O2 or TPS sensor maybe? It did give me a flashing check engine light for about 10 seconds this morning but it hasn't done that since.
View 5 RepliesWhen my Tig is cold, it seems to be very jerky or sluggish at 1500-1800rpm. There is definitely something happening at that range of RPM , almost seems like it's slipping and is jerky.
I know these 2.0's are notorious for the timing tensioner going (I have an 09) - could this be somehow related? I know that at a start I always get the famous rattle for a few seconds until oil pressure builds.
When starting my T-Reg leaving work yesterday, the yellow exhaust malfunction light (located in the rpm guauge -- it looks like an engine but the manual refers to it as an exhaust malfunction) came on and would blink now and then and remain on.
I proceeded to drive home and the entire ride was choppy and the engine was hesitant and misfiring. When I arrived home, I turned the Reg of and then back on again and the light never came on. I drove it around the block and it was fine.
We have been experiencing tremendous cold weather in the Northeast (-20 to -30 with the wind chill). Reg started fine this morning, no light. Was this a function of the computer resetting itself?
I'm getting a really choppy low RPM drive. If I'm above 2-2.5k rpm it runs okay but as soon as it drops under 2.5k it starts to run very choppy and loses power and Boggs in and out of power regardless of how much throttle input I give it. I had a tune up done last year and a recent oil change...
View 1 RepliesWhen I press on gas petal the car hesitates and seems like it is having trouble accelerating. It also does this when I accelerate up a hill actually it is worse. The mechanic changed by spark plugs and coil pack and it is still doing it. What could be the problem.
View 4 RepliesMore lately I've been noticing that when moving slowly, if going over a bump in the road of any sort, the steering wheel seems loose and the car wants to jump to one side or another slightly.
Picture moving straight ahead, and hit a rough section of or a small pot hole, and the steering wheel will move by itself to the left or the right quite a bit. I haven't noticed anything on the highway.
What can cause that? How should I go about describing to the service advisor so that it doesn't seem trivial? Last thing I want is a steering rack or major front suspension component slowly dying right after my warranty runs out. All I know is that it has struck me as "hey this doesn't feel normal".
Am I just being overly sensitive now that my powertrain warranty has months left on the clock, or does this sound like a legitimate concern? The last few things I've had them look into at the dealership during other service visits have been returned to me as "no problem founds" and I'm starting to feel like I'm just going crazy.
After some additional googling, it seems like I'm describing something commonly called "bump steer"... how much bump steer is normal for this car with stock suspension, I don't know... all I know is that I seem to have become acutely attuned to it whereas I never noticed it before. Hopefully I don't get the "we didn't notice anything wrong" again if I mention it, and whatever it is, is covered.
