My 1.8 is having a stutter/hesitation in first gear when I first start driving. No cel besides a misfire in cylinder 1 that I got yesterday afternoon. The hesitation began well before that though. Researched the topic but could not find similar issues.
View 4 RepliesReplaced my coil packs/sparks, and just got around to changing my N75 valve today. The rough idle issue is gone but now when I go WOT it boosts but goes from 15psi-12-13-12-14-12...etc. I've checked and there are no boost leaks. I do have a CEL saying I need a new bank 1 sensor 1 Oxygen sensor. If it is that, why did this problem arise as soon as I changed the N75 valve and wasn't present earlier?
View 1 RepliesSituation 01 Jetta AEG 2.0L codes catalyst below threshold and random misfires.
•found exhaust clogged due up catalyst. It was actually making contact with the rear O2
-replaced cat as an assembly and reset codes with Ross-tech
• start up, idles perfect no hesitation smooth. Road tested it and upon entering freeway ramp at it started stuttering/misfiring
• CEL flashed for cylinder 3 & 4. Inspected wires found #3 lost continuity, installed new wires.
•road tested and same result but only 4 came back. Swap plug with #2 and retested.
• #3 and 4 misfire came back again
- shooting in the dark to identify which way to go with it I tested:
•compression was solid 140
•fuel pressure 35 psi at idle and 45 when snapping the throttle.
-Suspicious spec is 55-72psi
•squeezed the return line to inspect if the Fuel pressure regulator valve possibly leaking excess.
Psi never went higher than 45 at idle and throttle snap to wot
•graphed the tps signal smooth with out drops or glitches up to values of 84 according to toss tech scan tool
•looking at measiring blocks one item that was odd is engine load at idle 99.5%
-swapped parts with known good parts with a good running 2002 Jetta aeg motor.
•MAF -no change
•ignition control module/ coil pack no change
-today ill be checking fuel pressure at the fuel pump and inspect if the fuel filter possibly clogged.
This morning my cars battery was dead and when I tried to pop the clutch to start it it went into gear but nothing turned on. When jump starting the car it turned on I drove it for a little while and was idling when it shut back off (battery was dead again). I came back to the car in a couple minutes, tried to start it and it started right up. I'm not sure what to think of this.
View 4 RepliesI have an '02 GTI VR6. It died on me on the freeway after surging then limping to a stop and wouldn't restart. I replaced my fuel pump 5 months ago and now I suspect that it has died again, but I want to be absolutely sure that the pump is the problem before I replace it again.
Last time the car would sometimes hesitate in 1st and 2nd for a couple weeks before the pump actually went bad. This time it seemed fine for 5 months then just went out.
The pump does not prime when I open the door. I checked fuse #28 and it's not blown, but there doesn't seem to be any power to it. I tested the power to the fuel pump connector. When I turn the key on I get ~12v for a split second then nothing. While cranking the engine I get ~9v constantly. I hooked a square 9v battery straight to the two outside connectors on the pump and nothing happened.
Can I be sure that the pump is the only problem? Obviously it's dead, but is there any reason for fuse 28 to not be getting power? And should the connector only be getting power for a split second when the ignition is turned on? I tried a different fuel pump relay with no change.

The problem: Very hard to get a smooth shift from gear to gear. Trust me, I know how to drive, but I can always feel the car shifting into a different gear if you know what I'm saying. On my friend's bone stock Jetta, I just let the clutch out without gas in between shifts and you don't feel a thing.
On my car, you feel EVERYTHING. People have told me the light flywheel will make the ride more uncomfortable in many ways, especially since the RPMs drop much quicker in between shifts than stock.
I have a 2007 es 350 106000 miles. Other day it happened car stopped i took it to my mechanic and he looked at the codes and it indicated key fob prob and something with the trans. Now it happened again. Car wont go into any gear.
Past few months i noticed a stutter at low rpm. i read a lot of people had tourque converter problems when this happens.. My question is i was just gonna change the converter and see if it fixes it but I don't know if the trans is shot to.. it was shifting fine only the shutter at lower rpms....
I got new brakes put on a few months ago month (semi-metalic)... Any way anytime I drive and it is raining, when my car comes to a to a complete stop, and I hit the gas to shift into second gear my car sort of stutters like it doesn't want to shift but then it does.
I took it to two mechanics MULTIPLE times who even drove it in the rain and they couldn't find a single thing wrong. they hooked the transmission up to the computer and noticed nothing.
It has happened multiple times and its both been raining. Could it be the tires aren't gripping the road and that's why my cars shifting funny, like the tires aren't caught up?
just bought a 2003 camry 4 cylinder with 126xxx miles automatic, everything seem fine when i was test driving and all. I bought the car and finally drove the car for around town running errands and all of a sudden i started to noticed a stutter in between shifting from 2nd to 3rd gear.
View 2 RepliesWhen I reverse (and wait 3 seconds just to ensure the gears are engaged), on occasion I feel a stutter/kick.
To offset it, I will tap the pedal when reversing so its not continuous. What this could be?
I have a 2000 Echo with just over 200,000 kms on it. The problem I am having is that when the car is started it will idle fine but when put into gear will randomly stutter and sometimes die. After is has run for about 10 mins it won't die but still stutters quite a bit. The problem gets worse the colder it is outside. If it's above 0 deg C it won't die but still stutters. At highway speeds it almost feels like the car gets jerked backwards for a split second every time the engine stutters (misfiring?).
Spark plugs are about 1 year old. Just put in a new air filter and oil change. A friend suggested it might be some water in the tank but fuel line antifreeze and sea foam has made little improvement.
I have a 2006 Jetta with a 5 speed manual transmission and 35,000 miles. The engine randomly misfires causing it to stutter or stammer. The check engine light is on and has been for several weeks. Occasionally the check engine light flashes. I took it to a local mechanic who ran a series of diagnostic tests (no vacuum leaks) and they recommended having all the ignition coils replaced for all 4 cylinders. They also replaced the fuel filter. I did so but the problem soon returned to which they referred me to the dealer.
I decided to take it to a VW specialist in town and they replaced the spark plugs for all 4 cylinders. They noticed that some of the plugs were black with a buildup and some were clean. The problem soon returned. The VW specialist also recommended that I take it to the dealership as they too had no clear idea as to what the problem is.
The car did suffer rodent damage in 2007 but was still under warranty so all the wiring that had been chewed on was replaced. I experimented using premium gas and regular gas. Premium gas seems to make the problem worse. Also, the misfires seem to lessen as the weather gets warmer. I would like to fix the problem to avoid any catastrophic failure but am trying to avoid throwing money away on any more guess work.
I'm most likely picking up a 03 jetta glx vr6. Thing is the 6th gear is out. Is the entire transmission about to break or is it a common thing?
View 16 RepliesLLast night I was driving. I got off the highway and pulling on to the main road in 2nd, I ripped on it and went into 3rd quickly. It basically kicked it out of gear, and didn't seem like I had any other gear besides 1st or 2nd. Got to a local gas station in 2nd, and I originally thought my linkage had come off. While trying to back into a spot to make life easier, there was no reverse. seems like the trans is binding up. Aligned the linkage anyway, when the car is off, it goes into every gear, but when it is on, it feels like 1st-2nd-nothing. If I roll the car backwards and then forward, I have 1st. Other than that, it will not engage. If I put the trans in reverse and then try to back up, it feels like the trans is binding. Same with 1st, unless the car is running. Traction control light will not turn off either, will have it scanned this week to determine that issue...
Ive seen most people have issues with the 1st-2nd shift fork and have this causing the reverse issues.
2005 GLI 1.8t
The car was starting to have issues going into gear after a night of cruising. Then I was experiencing what I am thinking was clutch creep. The clutch would be down and in gear and the car wanted to slowly roll.
What I have done to try and fix it:
I have bled the system many times to get all the air out(i believe), and also readjusted the the linkage. NOW, the car will not go into gear when it is on but will when it is off. I have the car on stands at the moment and it will shift through all the gears when the car is on just the wheels spin since it is in the air.
The clutch/flywheel/pp/throw out bearing all have less then 2k miles on them. Tranny fluid has been replaced with Penzoil syncomesh. I have yet to ever do a hard launch.
Clutchmasters Fx400, OEM DMFW.
Car is an 02m trans w/o the black cap in the side so I cannot do the washer/gasket mod for clutch creep. Believe I have to order NLS shim kit and put behind the throw out bearing.
Over the past couple weeks sometimes when i turn my car on it wont rev above 3100 rpm in any gear. The car is a 5-speed jetta 8v 2.0 and I'm just looking for any insight as to what is causing this problem. My check engine light is on and i had the codes read and there was a bunch, "catalyst system below threshold bank 1", " ignition coil A,B,C,D circuit primary/secondary malfunction", and "camshaft position sensor "A" circuit high input". I'm not sure if these codes are related to the problem but i had to have the whole top end of my engine rebuilt not even a year ago and all of the ignition coils and sparkplugs were replaced during that time.
This problem does not occur every time i turn the car on however, i did notice that sometimes when i go to turn the car on instead of the car starting in quickly, it will start hard after sever cranks and this is usually when i have this issue. it is very weird almost like there is a rev limiter on and i can usually fix the problem if i get up to highway speeds and downshift hard into 3rd and the car will shudder once or twice and will drive like normal again. What could be wrong i was thinking it might be a bad O2 sensor or a vacuum leak somewhere.
Just to clarify what i mean by it wont rev past 3100 rpm i mean that i can start from idle and accelerate normally and when it gets to 3100 rpm the power goes away and will just stay there even i put my foot all the way down. I can shift up and the same thing will happen i will accelerate normally but then once i reach 3100 rpm again it will stay there.
Have a 20th with the 02m six speed ... Car won't go into any gear, except reverse ... Tried with the car off or on, clutch in and out with no luck ...
I took off the linkage from the engine bay and can only manually get the car to go into reverse ... Feels like it can't change "levels" ... Don't think it's clutch since because the car won't engage a gear even with the car off ...
Tried searching and no luck ... Thinking shift forks but hoping not since don't want to drop the transmission and it could be something else ...
I bought my first vw about a month ago. It's a 2003 GTI 1.8t with what I THOUGHT had a 6 speed transmission in it when I bought it. I hate to admit it, but when I test drove it, I never had a chance to put it into 6th gear.
Anyways, I replaced the shift lever, and shift cable (bad Bushings on cable and you can't just buy the Bushings) because it was hard to get it onto 1st gear without pulling the boot up, and pushing that metal part down. (I don't know the actual part name). Anyways it shifts great now that I have the cables adjusted however it will not go into sixth no matter what I do.
This leads me to think that maybe someone put a 6 speed knob on a 5 speed lever. However, the wear on the knob is exactly the same as the wear on the steering wheel. The guy at the local dealership told me he sold me parts for a 5 speed shifter box and that the 6 speed linkage is completely different and I 100% have the 5 speed trans.
The issue with the car is that the tranny won't go into any gear. With clutch in or out. I had very little play left or right or up and down. Not sure what could be wrong. The car has 120k miles and no mods.
View 2 RepliesI'm just having a mis-alignment for my gearing reverse is replaced as first and I have no second gear not reverse only 1-3-4-5 gears are being entered what can I do to fix this...
View 2 RepliesI have been experiencing some grinding when I go from 2nd to 3rd, so the first thing that i did was to replace my trans oil but it did nothing so I went to my mechanic and he said that I need to replace the gear synchronizer. What is the part number and the real name, what i need is what is in the picture below.
My car is a mk4 1.8T with 5 gears....
