GTI 337/20th Anniversary :: Misfires In Cylinders 2 And 4 One Or Two Times A Day
Okay vortex here's what's happening in my 20th. About a month or so ago a CMP sensor went out, so I replaced that with a OEM sensor, on my way home my car started to misfire. So I took it easy the rest of the way home. The next day I started my car up and there were no misfires, drove to school, still no misfires but the check engine light was still on from the night before, after school on my way to get the codes ran it started to misfire again but then it stopped a few min into the drive.
Ever since then it has misfired but not all the time but maybe 1- 2 times a day then it would stop misfiring after a few min/seconds. My and my friend did the coil pack test and all the coil packs were good, yesterday (10/14/10) I replaced my plugs with NGK BKR7E plugs gapped at .028, my car is chipped with unitronic stage 2 tunning and it still misfired. I am going to clear all the codes and restet my ECU, but can you till do that with a unitronic ecu?

Car: 03 20th with 6spd 02m trans.
Problem: Go out in the morning esp when really cold, and the clutch pedal drops to the floor. No resistance at all on it as if it's no connected to anything. I pull it back up and pedal starts to build pressure.
I thought slave cylinder searching on here shows a high probability of that being the issue. But the strange thing is the pedal feels like it's sticking at the midway point. Once pressure is built up to normal pedal pressure, if I opush it down and slide my foot off it, it will literally rise fast and the feels like it catches on something and pops to the normal top position.
So my thought here is that the Master cylinder is sticking somewhere inside and causing the pedal to hang up. The weird part though is that once the car is warmed up the problem starts to diminish. But if I drive long enough on the highway (not shifting gears) the clutch seems to start losing pressure all over again.
I have also had to top off the brake fluid reservoir about 3 times in 2 months. What is the root cause here?
GTI 337/20th Anniversary :: Extra Loud Whoosh Sound When Stepped On Gas - Random Misfires
So I was driving home from my girls house the other day, i stepped on the gas pretty decently, and instead of the normal "whoosh" from the intake, i hear the "whoosh" with an extra loud "whoosh" sound. Then when i came to a halt, the engine wanted to stall out and was sputtering incredibly bad. car seems to run fine @ 2k rpms+. Now it actually does crap out on me, so I am currently not even driving it.
I got fault codes p0300, 0301, 0303, 0304. random misfires in cyls 1,3,4 right? I checked my hoses and I don't seem to have a leak anywhere...
GTI 337/20th Anniversary :: Valve Blow Off With Vacuum - Negative Boost?
This is my other question. I have an APR program and turbo-back billy boat exhaust. I installed a boost gauge that gets the reading off of the intake manifold (fuel regulator.)
So if I'm just tooling along, short-shifting and only using 1/10 throttle, and my boost gauge never reads above -5, let alone 0 or positive, why does my valve release pressure?
Why would there be pressure to release if there is a vacuum, according to the gauge? I wouldn't think that a recirculating or blow-off valve would work in reverse.
GTI 337/20th Anniversary :: Shifter Console Box Broken?
I was driving today and when attempting to go to fifth gear and sixth gear the shifter went completely loose, but if I returned it to neutral and go back to 1st through 4th I regain feeling of the shifter. Could something within my shifter box be box be broken? I can go into fifth and sixth manually from the shifter tower on the transmission,

I took my car to a shop today to have some engine stuff checked out. One of the mechanics noticed the vacuum levels would drop to 28-30 hg when changing gears or going into neutral. Is this normal?
View 2 RepliesGTI 337/20th Anniversary :: Broken Glove Box Handle - Replacing The Door
Most of the info I could find recommended replacing the entire glove box, and removing the center console to do so. I found a replacement door on ECS tuning's website, but I can't find a DIY on replacing the door/lid only. Any way out on replacing the door only, are the same steps required/removing the center console and taking the entire box out, or can the ECS tuning lid be fitted without as much disassembly?

(6 speed)... I have faulty reverse lights, my speed sensor is working so I am sure it isn't the fuse, I am guessing this means the switch/sensor is broken. Where it is located, and what the correct part number is?
View 3 RepliesGTI 337/20th Anniversary :: 1st And 2nd Gear Shift Fork Broken On 6 Speed Trans
My 20th Ann. GTI randomly would not go into first or second (they move into place but are just limp there and not catching into the gear) I was told for replacement of new 6-speed transmission and they did not offer any alternatives beside replacing it completely.
I know there is a thread talking about this but I read about the shift fork, or a piece of the shift fork that breaks and this problem fits my exact description. Not much info on what I can do, or at least not specified. What is any cost effective way to get my gears back without completely replacing the transmission? Is there anything I can do to just replace a broken part or are there any alternatives?
GTI 337/20th Anniversary :: Fender Bender - Headlight Not Staying Still As Plastic Strips Broken
Ok, got in a fender bender a few weeks ago. The plastic strips (with the Torx screws) holding the headlight steady, broke from the impact. The headlight itself is fine, no glass was broken, headlight still works, but without those plastic things, it will not, of course, stay still. My question is...would I need to buy a whole new headlight just because the plastic tabs are broken?

I have an 2002 Volkswagen GTi 337 edition with the 1.8t engine in it. My check engine light came on so I went to my local autozone to check the code and that's what code it threw on the ODBII sensor. It says my problem could be a "failed clutch vacuum vent valve switch". It also revs about 100-200 rpms extra in between shifts and I'm not a mechanic but know a little about cars. I just don't know if I should replace the OEM clutch safety switch or what I should do about this.
View 19 RepliesFord Aerostar :: A/C Blowing Through Defrost Only - Where Are Vacuum Hoses
My 2005 Freestar (not the Freestyle) a/c is working properly except that it is only blowing through the defrost. I've read other posts about it being a leaking vacuum system on other ford vehicles that cause this problem.
1) I'd like to confirm that this Freestar a/c works on a vacuum system to open the a/c duct doors.
2) If it is, where are the vacuum hoses located? I'd like to check them to see if they are connected or if they have a hole.

View 2 RepliesFord Excursion :: Rain Causing Misfires In 2 Rear Cylinders On V10
My 2000 Excursion, 6.8L V10 misfires when I try to start it, after a rain storm, and for the longest time, I could not figure out what was going on. After much use of a garden hose, to make rain, I found the rear two cylinder wells, on passenger side fill with water, due to a design defect in the engine hood that causes run off down that side of the engine. I visited with a mechanic, and was told that the hood design is common to a lot of the F series trucks, and the 8 and 10 cylinder engines are prone to the water buildup in the passenger rear spark plug wells. I am going to try to put a shield of some sort, around the two cylinder wells, to divert the water.
View 7 RepliesTiguan :: 2.0 VW Engine - Breather Valve Stuck Causing Oil To Enter The Cylinder / Misfires
We have a 2009 2.0 Tiguan with approximately 60,000 miles. About 6 months ago, the check engine light came on so we took it in and found out the breather valve was stuck causing oil to enter the cylinder and causing misfires. Had this fixed an about a week later, the car acted up again. Took it in and removed & reinstalled the intake manifold. Both pricey fixes. The dealership said it was a problem with the 2.0 engine design. Now we have taken it in again to a local shop who is now informing us we will need to replace the intake manifold. He said the same thing about the engine design. Our concern is that this problem will need to be fixed on a fairly regular basis. We really love the vehicle but cannot afford the cost of this maintenance if it becomes routine and are considering trading it in for a Passat.
View 3 RepliesJetta - Volkswagen :: 2006 - Engine Randomly Misfires Causing Stutter Or Stammer
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.
