Golf IV / Jetta IV :: Engine Dies At Startup / Codes For Camshaft Position Sensor
I've got a 2003 Jetta Wolfsberg that is acting up, I'll do my best to describe and outline the steps I've taken with the mechanic to fix the problem,
Occasionally, when starting the car one of two things happens, (1) engine turns over, fires, and then dies. Removing the key, letting the car sit for 30 seconds and trying again usually gets the car started. (2) The car will start but will run VERY roughly (misfiring, sounding like the engine is choking out). Very much like this (only sometimes much worse, usually ending in a stall): [URL] ....
Turning the car off, removing the key, letting it sit, and then trying it again will eventually work, even though it might take a few cycles. Once the car gets running it almost always runs fine from thereon. (There have been a couple occasions where the car has gone into limp mode, even on the freeway. Pulling over, letting it sit, and starting it again almost always fixes the problem. I've not yet been stranded.)
Diagnosis & Steps taken:
I get regular codes for the camshaft position sensor and also for the MAP (Barometric pressure) sensor. Both have been replaced.The MAP sensor and the atmospheric pressure readings are off by about 30 (something like 960 and 990). My mechanic thought that maybe it was an electrical problem, he noted that the two sensors mentioned above share a common ground. He replaced the ground because it looked corroded. This brought the pressure numbers both to 990 and the car ran perfectly for a few weeks.One thought was to splice in a new wire to the MAP sensor, to see whether it was a signal problem, this hasn't been done yet. Another possibility was that there is a problem with the ECM.
I THINK, that the problems began just after having the computer flashed at the dealership two years ago. I'd got a code about an update and so the dealership did this. I don't know whether this could have had any effect on these problems, but the times lined up too well to not mention it.
Dodge - Ram - 1500 :: 1997 - Idle Roughly At Warm / Accelerating
I have a 1997 dodge ram 1500 4x4 with the 318ci engine. 140,000 miles. Fall 2009 I replaced the CAT (old one had broken loose and was rattling around inside) and both o2 sensors. A few months later, when I'd start the truck cold it would idle fine then as it warmed at idle it would run rough almost quit then idle up and run fine all by itself. When started warm it would idle fine then hesitate while acclerating a few times then run fine. No check engine light. Now, about 10 months later check engine light is on (P0138 o2 circuit high voltage bank 1 sensor 2). I have put about 5,000 miles on the new CAT. I checked the wires and connections for damage and found none. Also, new cap,rotor,plugs and wires.

I swapped transmissions in an 01 vr6 glx automatic car. The car will start and run perfectly until it reaches operating temperature. Once it hits 190 f it shuts down and will only start again if u wait a few minutes. It has me stumped. I have unpluged the coolant temp sensor, and Have checked for vacuum leaks and loose connections but no luck.

Ford 7.3L Power Stroke (1999-2003) :: Truck Hiccups Under Idle And Dies When Warm
I've been working on my truck for months now on and off. I thought i finally had it back, but i have (again) problems with running. it basically only ran for a full day (hauling trip) after getting it back up and running. next day, it died on me on the road.
The new deal right now is that I can make the truck start and it will run, but it has little "hiccups" or misfires that will happen every now and then. Once it gets warm enough, the idling sounds chopped (best way i can explain it). After "chopping" it will then run fine (until the next chop). then it seems that once the truck gets warm it just stalls out. When that happens (shutting off) i can't get it to start right away. i have to wait awhile before it'll start and that lasts only so long.
The truck puffs a tiny bit of white smoke. not constant but more like a "puh - puh - puh" ....I've changed out quite a bit of used up parts now...

Ford Ranger / B-Series :: 1997 - Rough Idle At Startup / When Rev Up Chugs Real Hard Then Dies
I am currently working on a 97 ranger with a 4cyl and 5 speed. its having some idle issues that i cant seem to pin point, you can start it and it will idle rough then when you rev it up it chugs real hard then dies. used my scan tool and all the sensors are good, fuel pressure is good, good compression, all 8 plugs are firing good and no codes. The other deal that has me a little confused is when I unhook the hose that runs from the air intake tube to the valve cover, I get a lot of vacuum at that port on the valve cover that the hose hooks to. Also when I plug it and pull the dipstick, I get vacuum at the dipstick tube. never seen this before but at the same time I've only messed with very few of these trucks so I don't know whats normal.
View 6 RepliesFord 6.0L Power Stroke Diesel :: 2006 - Rough Idle / Dies Warm And Long Crank
My 06 currently has 296k miles. 3 years ago I put a lot into her. Dummy plugs, stand pipes, STC, hg,studs, oil cooler, bpd egr cooler. Cleaned spool valves and fresh o rings in injectors. (Alliant) plus a lot more that I can't remember. Ran very very well after all that.
Fast forward to a few weeks ago. Driving down road and truck died as I let off pedal to slow down for turn onto my road. Took about 7-8 tries to get started back up. Icp was reading in the 300's until it finally started. Made it home. Shut it off. And started right back up.
Few days later truck died again same way. Let off to make a turn. Several attempts to restart icp was in the 300's again. Once it started building 420ish it sounded like it was firing a few injectors and slowly started running. The next time it happened the same way but when I got it back running I eased to my inlaws like less than a mile. When I got to their house and pulled in and went to back up to turn around the display on dash said low oil pressure and started missing a little. So once I got home started researching.
A few days ago I pulled out the low pressure oil regulator to check it out. It was clean but did have some mild scaring. I used some fine scotch rite and smooth it out a a little. It moved freely in the bore so I put it back together. Then pulled the oil filter cap off to check the little black valve. I noticed the filter was not dripping with oil like normally when I change the oil. And yes it's motor craft filter and cap. It checked out ok. Press it down and turned engine over and it filled and held. Let off of it and it drained.
Next I air checked the high pressure side. Applied air and waited until I could hear the air (IPR still open) then closed the IPR. Couldn't hear any leaks. Just a very very minor his and couldn't pin point where. So I went ahead and went to dealer and got new stand pipes and plugs. And ordered new print set for injectors. Pulled injectors and didn't see any smoking guns. Replaced prongs, stand pipe and dummy plugs and put it all back together. Cleaned the injector cups and hold down bolt holes. Torqued injectors to spec.
Got it all done and rotate motor by wire next to heater blower to assist prime system. Tried to start it up and it took two tries but fired right up and sounded smooth as hell. After it idled a few minutes I saw a haze from exhaust. It smelt just like fuel. A few minutes later started idle a little rough. Gave it some go pedel and it was rougher at about 1600-1800rpms and couldn't feel it above 2k. Got my laptop out with AE and done balance test. Did not show anything. No codes either.
Golf IV / Jetta IV :: While Driving Air Comes From Hose - Run Roughly And Miss
So I had a hose come apart that is located under the intake manifold on my 1.8t. It's some type of air hose because I can hear and feel the air coming out when the car is running, and it's also making my car run rough and miss, mostly at idle.
View 6 RepliesGolf IV / Jetta IV :: 2005 - Won't Go In Reverse At Cold / Shifts Roughly From 1st To 2nd?
Just bought a 2005 Jetta 2.0 4 speed automatic (non tiptronic) with 92,000 miles. This is the old 1999-2005 style, not the New Jetta that was introduced that year.
I've done research and have found that the transmissions on these bodied Jettas seem to be acting up.
This one shifts fine with a few weird things. When I start the car cold (this is in LA, so even over night the temps don't go below 60), and I put it in reverse, the car does not go into reverse for a good 3-5 seconds. This does not happen after the car has been driven for a while. After that it shifts fine, no delay.
The other symptom is sometimes the shifts from 1st to 2nd gear are a bit rough, with a thump sound, but nothing too out of the ordinary...if it wasn't for the other mentioned problem above, I wouldn't think twice about the 1st to 2nd shift as many automatic cars have some rough shifts. All the other gears shift fine.
I've done the basic research to know there could be a couple things causing this such as clutch piston seals and excessive drainback. I want some more info since I know there are my experienced people on this forum. Should I be worried and are there any things I should do immediately?
I have also found that these transmissions are sealed and can not be checked for oil levels with out taking to expert shop. I've also seen that they are very sensitive to overfill and any service needs to be performed by experts. Should I just continue and come back to this if symptoms get worse?
Golf/GTI VI :: Car Sputters And Dies At Startup After Parked For 20 Minutes
Drove the car, 20 min to shopping, and when I came out the car would sputter and die??!! it happened a few times.. it would crank for really a long time, engine would fire up but sputter & die. I was cussing & let the car sit at mall parking lot for a bit, thinking I'll have to cab home but it started up again after 10 min and drove fine. It happened on a parking lot, not on the highway.
View 24 RepliesKia - Rio :: 2005 - Car Starts Roughly - Idles Horribly For A Few Seconds - Dies
It's a 05 Kia Rio. I've recently put a bit of work into it due to a few issues which were fuel related, namely replacing the fuel filter/pump. It also has brand new spark plugs. That solved the issue that originally put it on blocks for a few months and it ran fine for the past few weeks.
Today I went outside to drive to work and got the symptoms in the title. I know it's not a spark issue because it does start, and I used it on accessory to air up my tires this morning.
I'm just not sure where to go next. I've done a bit of searching and have found recommendations for checking the grounds and the distributor cap.
While running at rough idle, depressing the accelerator makes it die faster, rather than keeping it running. It rained last night and this morning. It's about 70 outside instead of the 80-90 it's been the last few weeks. No check engine light, but I've only tried to start it about 10 times.
Civic - Honda :: 1991 - Idling Roughly / Dies Intermittently While Approaching To Stop
In the Car Talk column on 1/3/2016, it sounds like Lynnette's 1991 Honda Civic wagon was experiencing very similar symptoms to my wife's 2001 Honda Odyssey (189,000 mi) a few months ago. Rough idle, engine almost dies sometimes at stops, groans during acceleration. Additionally, accelerating between 40-60 mph our Honda would feel like it was "loading up," running rich or in the wrong gear climbing hills. I replaced the idle air control valve, which fixed the rough idle but not the other symptoms. Turned out I needed to reset (power cycle) the ECM and go through a curb idle/rev warm-up procedure so it would relearn the throttle position sensor's operating range after replacing the IAC valve. I disconnected the battery, removed and reinserted the hazard fuse, then reconnected the battery. Then from a cold start held the throttle at 3000 rpm until the engine warmed up to normal or the electric fans kicked on. Since then it's back to smooth, strong acceleration we expect from the Honda we love.
View 1 RepliesGolf IV R32 :: Misfiring At Idle After Startup
Car has been running flawlessly up until about 3 days ago. One morning got in started up and started misfiring at idle. Didn't think much of it as it does that on cold start. Driving down the highway when I apply 5-10% light throttle the car bucks and doesn't feel smooth. WOT is fine. Pulled into a gas station to fill up and it stalled as soon as I put it in neutral. When I tried to start it back up it started for a second then stalled out again. Finally I gave it some gas while I started it up and got it to idle on its own (idled around 600 rpm, down from my usual 800 rpm).
At this point I am thinking boost/vacuum leak. I leave the gas station and get caught in traffic. Car is not overheating. All of the sudden I notice a bunch of white smoke coming from the tail pipes. I pull over pop the hood to check coolant. No leaks and bottle is full. The white smoke smells like burnt oil. finally notice a VERY small oil leak at my turbo oil feed line. I checked the oil level and it was still exactly where it needs to be.
I have my buddy at the dealership looking over it now but I am really worried that I might have blew the turbo..
Golf V R32 :: Rough Idle After Cold Startup
If my car's been sitting - say monday morning after sitting all weekend in the garage- it runs rough for a little while. Sometimes only for a few seconds, sometimes for a little while after the idle drops. The colder the car is, the longer and worse the condition. It feels like a cylinder isn't firing.
After a particularly cold and wet spell (I had the car outside) it ran so badly it threw a code for one of the cam position sensors and #4 misfire. I replaced both of the sensors. That worked a little.
Since I was due for 80k service and saw a misfire when damp, I replaced the ignition coils along with the spark plugs. That worked a little more. But, it still does it. What else could it be if not ignition? Sticky valve? something else?
Golf IV / Jetta IV :: AC Gets Warm When Accelerating
When my car is at idle or cruising the AC works well. When I'm driving normally from stop light to stop light the AC gets warm.
I did have the pressures checked and they topped off the refrigerant. They also said the compressor is working well. I had all this checked before it started getting warm during accelerating.
Are there some things that I can look at?

View 18 RepliesGolf IV / Jetta IV :: Oil Cooler Leaks Only At Startup
I noticed last week when I leave the house in the morning my car was leaving oil striped down my road. Jacked car up Saturday AFTER RUNNING TO STORE found a little oil on bottom of my car but not nowhere near what I was thinking there would be. Cleaned motor fired up found no leaks at all . However this morning after car had sat 20hrs or so I looked under car before I cranked her up clean.
Got it cranked her up and oil was streaming from the oil cooler. Not on the block side but towards the front of car side of cooler. It did this for a few seconds then stopped. I am gonna order new front and rear orings for oil cooler. I am just stumped why it only happens at a cold start and for a few seconds not consistently.
Golf IV / Jetta IV :: CEL Comes On / ASR Light Follows Shortly After Every Startup
2003 gti 1.8t. I'm having a problem with this engine code, it keeps coming back and when the CEL comes on the ASR light follows shortly and will then come on after every start up.
For the p0171 I've replaced:
Crankcase vent hose.
Y split running to the pcv
MAF
Coil packs
Spark plugs
Fuel pump
I also have done a seafoam treatment through tbe intake and ran a bottle (twice) of injector cleaners through the gas tank.
Nothing has fixed the code. I found cracks in the brake Booster vac line and had the line replaced (brake light would flash under boost, doesn't anymore). Can't find any other leaks except for maybe the secondary air pump (which I haven't replaced yet).
The OBD2 monitors all run. the EVAP and catalytic monitor won't click over to ready. I have a new pcv and a fuel filter coming in the mail in another vain attempt to fix the issue.
Golf VI R :: Lope In Idle When Engine Is Warm
Here's what's done to the car so far:
Evoms CAI
Autotech HPFP Insert
UM Fully Loaded Stage 2
Magnaflow Catback
R8 Coilpacks
Now my problem lies in the fact that the car has an unusual "loping" idle once it's warmed up. I noticed it very slightly when I first installed the catback simply because that exhaust is louder than stock. Now with the tune it seems to be even more noticible and ocasionally the engine will stumble upon a warm startup. I've pulled up VCDS and looked at the timing measuring blocks during idle and it varies between 0 and 13.5 BTDC/ATDC, the lowest the revs go is about 700 and the the car idles most of the time at about 800. A few hundred miles ago there was a code for Fuel pressure too high (P0088) and an o2 sensor reading too rich (P2271), I saved said codes and cleared them and they have not returned.
