Golf IV / Jetta IV :: Cannot Hold Boost And It Fluctuates All Over The Place
My car is a 2001 Jetta 1.8t. the car is bone stock, I can not hold boost and it fluctuates all over the place. the dv sounded like a flutter until I bypassed the n249 now it sounds like a steady pssh. car still would only make 4lbs of boost and drop to 1-2lbs after 3500rpm. I pulled the line off the n75 to wastegate and did a pull. it boosted to 8lbs spiked to 15 and held 4lbs, if the tires spun it would spike to 12-15lbs and drop to 4 again. I replaced the n75 today and now will still spike high if I spin, with traction boosts about 8lbs which I believe is stock but then drops to 1-2 lbs then up to 4 down to 1-2 sometimes up to 6, it seems random. I also pinched off the dv to see if that was the problem but same thing.
I'm wondering how my car could lose boost with the wastegate actuator unhooked, I can not find a boost leak(not saying there isn't one, but haven't found one), the car holds more boost with the n75 unplugged and under acceleration, with n75 plugged in it seems like 3 surges per gear?
Car throws one code p1473 its an evap code.
The wastegate sounds like its closing when I pull the rod and let it go, lots of tension on it.
Golf IV / Jetta IV :: Pull Up Really Hard To Get Parking Brake To Hold?
I have to pull up really hard to get the parking brake to hold. If I'm on a hill forget it, I yank up really hard and then leave it in gear just in case. I have installed new cables and pads. I have also have the lever adjusted so it starts to catch when you pull it up about 2-3 inches. I've never driven another mk4 so I don't have any other reference to how well the parking brake should hold but I would think that I wouldn't have to pull up this hard to get it to habe any real holding power.
Any other vehicle I've driven with a hand brake I could easily lock up the rear tires. I'm lucky to get mine to lock while pulling so hard I think I'm going to break something. I've searched around and have only come up with threads about replacing cables and adjusting the lever. I couldn't find anything like the problem I'm having. Is this normal operation for a mk4 or is there something wrong with my calipers that needs to be addressed? My regular brakes work fine and the parking brake arms on the calipers allear to be functioning properly. They contract then spring back on their own
Golf IV / Jetta IV :: 2004 - Have To Hold The Shifter Until Clutch Is Engaged For 3rd Gear Position
I picked up a 2004 GTI not long ago for pretty cheap because it had a few issues. I am working my way through them. However, having 3rd gear issue.
All other gears are perfectly fine but there is way less play in the shifter in the 3rd gear position and I have to hold the shifter in position until the clutch is engaged (pedal up) to avoid the gear grinding. Once the clutch is engaged it stays in 3rd gear fine. It doesn't matter if I am moving from 2nd to 3rd or 4th to 3rd. Same deal. I have aligned the shifter several times using to proper procedures with no effect.
It never grinds 3rd with the clutch disengaged (so the synchro is fine?) and it will bang shift no problem. Oh and the clutch is less than a year old. It was installed by a shop before I bought the car. It's not really a big deal, but I would like to fix it. If I have to swap the trans that's fine, but need to figure out if it is a trans or linkage issue first.
Volkswagen - Beetle :: 1969 Will Not Hold Idle
I have a mystery on my hands and am at a complete loss. I have a 1969 Volkswagen Beetle that will not hold an idle. It will start up just fine and as long as you have your foot on the gas, it will stay alive. As soon as you let off the car sputters and dies. Another symptom is that the is a miss in the engine, not sure if the two are related or need to time it and then check on the idle. Here is what I have done in an attempt to fix the issue:
I have been able to adjust the idle to get it to stay alive for about 30 seconds longer, but no matter ho much I adjust it still struggles and dies. Idles very rough no matter what.
Cleaned the carb (not a rebuild or anything, but just gave it a real good spray of cleaner)
Replaced the condenser and points (adjusted the points properly etc.)
Replaced and gapped the spark plugs
Replaced the idle cutoff solenoid
Adjusted the automatic choke
Cleaned the carb (not a rebuild or anything, but just gave it a real good spray of cleaner)
Some have suggested a vacuum leak, and i know i have to put some sort of solution on the vacuum connections, but since I am relatively new to the world of VW beetles I am not quite sure where those are and what to put on and what to do if there is a leak.
Phaeton :: Won't Hold Idle / Flat Spots During Rev
I had the car in to replace the inner CV boot and repair a leaking trans flex seal. About 30 minutes after I left the shop, I lost all acceleration and the car basically crawls around. Halfway to work and almost late for meetings, I was afraid it was a failing fuel pump so I rigged both fuel pump relays closed and it seemed to get better... I pulled the relays while at work, re-inserted at the end of the day and headed home. About halfway home the acceleration issues came back (with the rigged relays), and I barely made it to my driveway. Pulled codes, and see these:
16732 - Camshaft Position Sensor (G163)
P0348 - 001 - Short to Plus - MIL ON
18711 - Leak in Air Intake System
P2279 - 002 - Lower Limit Exceeded - MIL ON
16408 - Bank 2: Camshaft B (Exhaust)
P0024 - 008 - Retard Setpoint not Reached (Over-Advanced) - MIL ON
I checked for vacuum leaks and can't seem to find anything tell-tale. I have seen the Camshaft Position Sensor before, but the car ran fine. Probably time to get around to replacing it, but what about the Leak in Air Intake System? Car really hates to idle. Also, MIL is pretty much always on for me due to an unhappy trans that disables ESP.
Passat (B5) :: Just Cranks For Long Time / Won't Start - Cannot Even Hold Idle
Tried to start it, it just cranks for a long time, it can't even hold an idle. After 5 minutes of cranking and trying to get it running, it starts up just fine like there isn't even a problem. It just started to happen today. I have a 2004 v6 2.6 glx, completely stock.
View 3 RepliesFord - Escape :: 2003 - At Start Up Won't Hold A Steady Idle
2003 Ford Escape V6 ... So . . . my car runs fine almost all the time and I love it. But every couple of weeks when I start her up she won't hold a steady idle. Unless I hold my foot on the accelerator pedal she dies right out. I have had to limp home as she dies at each stop light. I have tried disconnecting the battery to reset the computer but it never seems to work. On the drive home, there will be episodes of misfiring after which the computer will reset itself. (The dash instruments go to zero and then back into normal range while I am driving down the road!) After a couple of resets, the car drives fine the rest of the way and continues fine for a couple of weeks (except for some misfiring at idle).
And at cruising speed there is a chatter behind the dash which sounds like its from the computer--very intermittent and only at around 45-60 mph--it only lasts a few seconds and goes away when I changed speed. The car is great in every other way after 104,000 miles. In the past 12 months, I have changed the thermostat, the plugs, the PCV, the fuel filter, and the air filter. A year ago both Brake Sensor rings cracked so I replaced both CV shafts. The crankshaft position sensor code came on twice and I replaced it twice. I do all my own work but I am stuck in a rut right now.
Golf IV / Jetta IV :: Vibration Going On At Idle
I drive a 12v VR6 and this morning the cars idle was very rough and different than normal, while at idle the engine vibrates a good amount but once I push on the gas the vibration goes away? Bad motor/ trans mounts? She also sounds a lot deeper now, is there anything I should be looking for? Doesn't sound like my chains are off or anything and just pulled the wires and cleaned out around the plugs, should I check the throttle body?

Alright Ive had a misfire on cylinder 1 for far too long. I've replaced all ignition coils and plugs with oem parts. Also replaced fuel pump and filter with oem. As well as 2 injectors. Before I would misfire under load, now I misfire at idle..wiring looks good and not cracked from what I can see. Only codes I reciece are random multiple misfire, misfire cylinder 1. And diverter valve mis function because of my BOV. So what do I do now vortex?

After about a 45 minute drive yesterday the EPC light came on, idle went up to 1200 rpm's and when I turned off the car it wouldn't turn on, just leaving the ignition for about 5-7 seconds is when the car finally started.
Today, again after a 45 minute drive the EPC light came on again, same symptoms, except that the car stalled and I had to turn the ignition again about 5-7 seconds for it to start. No other light is on, and the car would start fine after about half an hour rest with no EPC light.
Golf IV / Jetta IV :: Air Conditioning Almost Stalls At Idle
I had just picked my car up from the shop after getting a new 3" downpipe installed (welded to stock cat) and attached to stock catback exhaust. I mention this because I never had this problem before and have already had installed a TIP, boost hose kit, DV, larger intercooler, and breather hose kit, all for a Unitronic Stage 2 tune.
So I go to turn on the A/C and the idle drops to about 400 rpm, almost stalls, interior shudders, vacuum jumps from about 20 to 10 as the engine revs itself a bit, and then it settles back out and the car runs fine (awesome with the new tune) and A/c works great. I have used the A/C a bit since getting all other upgrades done and never had a problem, or I didn't notice, but I'm wondering why a new downpipe would make a difference. I tried turning it on and off a few more times and the same things happened at idle, but after that initial dip and near-stall the engine was just fine around town and on the highway.
Golf IV / Jetta IV :: Rough Idle Between 600 - 800 RPMs
My golf 2.0 vw isn't doing so good right now. It has 227000 miles on it. It has been driving great, and then last week it started to idle rough. It idles between 600-800 rpms. it fluctuates between 600-800 rpms. It had the check engine light on before this happened i was told by my brother that it was an 02 sensor. I had it checked for what is causing the engine light to come on today at o Rileys, and it came up with 11 codes. Some of the codes where 02 sensors, it was running to rich, needed a new computer, evaps system, fuel pump, fuses, coil pack, spark plugs, It shakes when you sit in it when it is idling like not a bad shake but a small one you cal feel, l'm including a video of it running.

View 1 RepliesGolf IV / Jetta IV :: 2003 - Low Oil Pressure Only At Idle
I have a 2003 golf gti 1.8th awp with 160k miles. I was due for a change so I grab castrol edge 0w40 the euro formula like I normally do but the stp filter was on sale with it so i used that. a week later the low oil pressure light comes on when the cars fully warmed up but only at idle I can review it above 1000 and it'll go away. I decided to change the pressure sensor sense it's cheap and easy nothing. I also went to a Bosch filter which I had before same thing light comes on only at idle.
So I decided to drop the pan and clean the pick up there was some crap in it wasn't to over clogged. I did little notice plastic piece surgery in the pan but when I first got the car the dipstick was deteriorating and I know a few little prices fell in there. Also noticing a fairly clean looking motor and oil pump so I don't think sludge is a issue. Anyway I decided to try mobile 1 0w40 euro formula and I read k&ns 3001 filter is a good oversized filter. Anyway light still comes on only at idle, what next?
Addition info the the car it's a stage 2 apr tune with euros ports pcv hoses turbo inlet pipe 42dd's catless exhaust recently had a leak in radiator so replaced that and the fuel pump went out within the last month or two
