Within the last week, while sitting a stop light, the car will very briefly (2 or 3 seconds) shudder and stumble. The RPMs drop a couple of hundred +/- and then it's fine. I have no other symptoms - no power loss, or reduced mileage. I've not experienced this before and it's happened three or four times recently. Is this indicative of an impending failure of some component?
View 3 RepliesIs this a sign of a turbo going out or ? my GTI currently has 1700 miles on it and not all the time, but in the past 1700 miles the car has stumbled or jerked around a bit when at idle, i.e. the rpm's don't do anything but it seems like it's misfiring or something a few times then generally clears out. Same when driving sometimes, cruising along and it seems to misfire or stumble around but it clears up as well. Haven't noticed anything else weird but it's annoying and worrisome.
View 8 RepliesWhile starting up the 337 this morning, I received a stumbling idle from the engine. I popped the hood and noticed that there was a bit of bluish / purplish discoloration on the tops of the coilpacks. Gonna replace the packs and plugs today, just wanted to know if there was anything else I should check for.
Also, this wouldn't be related to the death of the driver's side door lock module would it? (I noticed that when i opened the door, the light and the fuel pump didn't prime....)
My truck has been doing this since I got it and I can't figure it out. It's a 2000 Ford Ranger XLT 2.5 5Spd. It runs fine if you don't rev it above 2500-3000 rpm. After you rev it that high coming down to idle it is stumbling real bad and sometimes stalls. I've been driving it like this since I got it, and it does fine other than this. It gets better the longer you drive it, but it still will do it if you rev it high enough.
Here are all the parts I personally have changed (previous owner said he did the plugs and wires and air filter, which it looks like he did but I'm about ready to change them myself):
-Fuel filter
-coil packs
-timing belt
-egr valve
-cleaned throttle body
-iacv
-tps
-thermostat
So i have a 2000 ford ranger 2wd 4cyl .190k miles. My issue is the motor has a very rough/shaking idle,abs light on,and check engine light on.it also continues to blow fuses to the tail lights and dash, haha
Ive had it since it was at 40k and has been a great truck,although lately i have really neglected it.ive changed the spark plugs and new wires new timing chain. I would d love to start trouble shooting some of this stuff this weekend if the weather holds up.
I have a 2002 7.3 Excursion with DP Tuner. Truck has 167K on it. My check engine light came on when I was driving to work this morning. Stayed on for the ride home. Appeared to drive ok - a little rough - but it has been that way for a while. When I got home I plugged in the AutoEnginuity and this is what came up:
So it appears I have a glow plug issue. That does not surprise me as I have had some rough starts this past winter. On a whim I ran the Cylinder Contribution Test and it completed successfully. Yet when I started the truck again it completely falls on it's face when accelerating. Here is a link to a video: [URL] .....
It did this once about a month ago. I was driving to work and stopped at a light and when I tried to accelerate, it did this. I limped to a gas station a 100 yards away. I let it sit and started it up, drove home. Went in the house and did some googling and of course after I came back out, it worked fine. Has not done it since.
I just bought this car... today... ran great until I got a few exits from my apartment (I think the car knew I had my hopes up for successfully making it home) and all of a sudden the car shut down. There was no smoking, shuddering, or weird scents of any kind. Had my girlfriend following me and she said she didn't see or smell anything... the oil level is good, pretty clean... coolant is clean and pink... timing belt was just done about 5k ago... but she cranks and stumbles a little but that's about it. Battery died from repetitive attempts at starting and now I think that old girl needs to be replaced... but does this sound like a crank position sensor issue like I'm guessing? or possibly cam position sensor? Also might add that the dipstick and oil cap hole had a little smoke coming out of it when I pulled it to check the oil situation... B5 1.8T wagon

View 5 RepliesAfter 90K miles of using Castrol 5W30 dyno and changing it every 3-3.5K miles , I have just changed to 0W40 Mobil Synthetic. I have a 2002 Passat V6 automatic tip . I am hoping to have a smoother idle at stop lights .
View 5 RepliesI have a 2002 passat. It is a 1.8T. I have a stock turbo, it has a full aftermarket front mount hooked up. It also has a blow off valve. OK my issue is that I believe it runs too rich. When I drive the idle will drop and the car will stall out. It has its good days and bad days. What can I do to make this not happen? Would I have to have a recirculate the air flow again? Should I have everything stock again? Would anything else stop this happening? As well as how much PSI does this car stock suss posed to push? I have a boost meter that only reads max 5 psi. Should it be more? I am new to VW and brought the car off a friend.
View 17 RepliesI have a 2002 1.8t with 90,000 miles on it. I have it serviced for new Timing belt and water pump (metal impeller, according to the shop) 3 months ago at this shop. The overheating problems never went away. The problem is that it overheating at heavy traffic or idle after a while or after heavily drive, but it cools off quickly when I rev up the engine a little bit, or after getting out of traffic again.
I have another shop diagnosed, they first told me the cooling system is leaking and may trapped air inside so they did replace thermostat, coolant housing assembly, flange seal, pipe sealing o-ring. they re-test and turn out there is no coolant flow and suggest that is it the water pump that fail and ask me to go back to the original shop for the Water Pump warranty. Additionally, they flow test radiator and its fine.
I did return the car back to the original shop and they tested and said the heater core is clogged with debris and that would cause the overheating. They asked me to replace the whole heater core that would cost $1500. But I know for the fact that I have heating in the car and it is hot!
Is there any other reason than what have been replaced or tested (thermostat, radiator, air trap, new coolant)? I think it could be the aux cooling fan since its never turn on when overheating, only when AC is turn on, is it supposed to work this way? Spent too much on this car and hopelessly the problems went away but it's not.
2002 Passat v6 - climatronic control...
I have just cold air blowing at idle and under load. I have read posts and checked the following: temp remains at 190, heater coil hoses-both are hot and removed the dash to see if the flapper door (red arm) was moving-it is. Any other things I can check?
I have a 1991 gmc 1/2 ton with 200K on it. Its a 350 engine. The engine has been stumbling for a long time. I've tried many things ...new fuel pump and filter...complete tune up.....checked all vacuum lines..replaced a couple lines...EGR valve.....changed head gasket and intake gasket. Checked the warm up flap inside the air cleaner. I am now very very frustrated.
This stumbling happens often but intermittent also....sometimes worse than other times like the truck is about to stall. The truck seems like its being held back like a loss of power. The truck will begin to stumble so i will pull over and rev it up and it seems to clear itself for a short while then right back to stumbling.
Upon warmup in the morning she seems to run fine until hot. No codes being thrown ...service engine light NOT on. Even while at a stop i will hold the throttle part way and revs at different rpms. I am now at a loss and feel defeated.
2002 accent 1.6 motor and 5 speed,when I take off the motor sputters for a moment then is fine and if I let it slow down in any gear and step down on it it will sputter again then is fine, so far I have changed the plugs and air filter cleaned the throttle body and MAP, the wires and timing belt were changed out not long ago, took it in and hooked the machine to it and it said misfire bank 1 oxygen sensor upstream so replaced it and still have the problem, the body has 200,000 on it and the motor 100,000.
View 8 RepliesJust stopped by the dealer to check on some parts, went to start the car, and this happened. Also smells rich as hell. Did I just drop the ECU code?
View 24 RepliesI have an '06 Forester XT 2.5 turbo that has, what I can only describe as a stumble around 2500 rpm. The car's maintenance is always up-to-date, and never has anything under 91 octane run in it.This started out when you had the cruise set and now does it all the time whether or not the cruise is used. I've had it to 2 shops including a Subaru dealer that had it for a month and couldn't find the issue. We've been through injectors, coils, maf sensor, etc. to no avail. The trouble code that we're given is a misfire in cylinder 1. We discovered, while trying to find the issue, that there was only 30psi in that #1 cylinder and the valve guides were the issue. So the motor was pulled, heads planed, etc. and new guides installed. Also, put in a new timing belt, and so on, that is usually done when the motor is out.They have done a leak down test and compression tests as well. This is my wife's car and she absolutely love it, so I need to get this figured out.
View 2 RepliesThat's the best way to describe what's happening. It goes like this:
Car is cold. Within the first two miles, in third gear (manual) around 30-35 mph, it has a momentary stumble that's very noticeable and it jerks for that second. Then it's back to normal.
The dealer recently replaced an O2 sensor (which has had no effect on the stumble). 2010 Golf TDI....
I have a stumbling engine when my chevy shifts into over drive. I have new plugs wires dist rotor coil ign module fuel filter air filter. Checked timing with auto advance unplugged and it is not @ TDC but about 4 deg advanced. It is also not consistent in its stumble.
View 19 RepliesMy 3.5 intrigue seems to stumble while driving it. It feels as it the engine is stumbling or loses power for less than a second and it will do this a few times in a row and will be fine for awhile and then repeat itself.
This can happen while cruising, slow acceleration or at a stop light. I don't really notice it under harder acceleration. When it does happen i do notice that the rpm's drop a very slight bit.
I'm a newbie who just took ownership of a 1982 turbo wagon. It's been sitting a while but started right up and ran well for about 20 miles until it began stumbling on acceleration.
The car starts easily and runs smoothly until it gets hot and then it suffers severe hesitation and stumbling. Occasionally it will stall but starts right up again. It has never failed to restart immediately.
On a cool day, it will run smoothly for thirty minutes or more before the problem begins. On a hot day, the problem begins in five minutes.
We bought it in 2010, since then we have replaced 5 ignition coils and 2-3 batteries. Everytime the car acts up, the VSC and traction lights come on and the car starts stumbling and hesitating. The car eventually dies within a few minutes. Pull up codes and its always been an ignition coil.
Well we had all of these covered under warranty until the warranty expired in Aug. A month ago this happened again, and thought the battery was dead. It ended up being #4 coil, so I replaced.
My wife drove last week and lights came on and lights started going on/off and dinging at her and the car died. I jumped it to get it home, turned off the car and was dead. Voltage at battery was 9 volts.
I charged overnight and started the next day. I pulled negative battery cable w car running to check alternator and it stayed running, so that's good. The car is now starting just fine again.....until this happens again.....which it will.
My question is what in the heck can be making all of the coils go bad and why is the car intermittently throwing warning lights and just dying? This last time the codes pulled we P0345, PO365, PO390. All of which I don't see an explanation for.
