Golf IV / Jetta IV :: Misfire On Cylinders - Cracked Harness / Vacuum Leak?
I just bought a 05 1.8T Jetta 116,000miles. and need diagnosing it. It misses all the time. Has new plugs I tried two other sets of coils (from my 2.0 a4 and my dads passat) and it made no difference. The SAI was taken out but nothing is blocked off. Also the coil pack wiring harness has cracks on the big brown wire where it goes down along the block. I'm getting these codes on my vag-com.
16687 cylinder 3 misfire
16686 cylinder 2 misfire
16688 cylinder 4 misfire
17766 cylinder 2 open ignition circuit
17763 cylinder 1 open ignition circuit
17769 cylinder 3 open ignition circuit
17772 cylinder 4 open ignition circuit
So am I correct in thinking that it's from the cracked harness? An not a vac leak?
Golf IV R32 :: Where To Put Vacuum Check Valve For FI
I need to put a check valve into the vacuum line that runs to the gas tank. I know that this line is somewhere in the rear passenger side of the engine compartment, but there's so many lines there that I find myself confused when I look at it.

It makes a weird 'fppp' air shooting noise before the exhaust note and my 2003 gti vr6 makes the exact same noise. It sounds like it's coming from the intake manifold valve and not really the filter, but I'm not sure and yes my filter is clean, the noise also sounds a little bit more obnoxious and problematic in real life. What it is, I thought it was a vacuum leak but I don't wanna bring it in till i know exactly what it is,

02 F150, 5.4 gas motor, about 338k miles. Bought this truck well used so I would have a truck when I needed one. Someone has removed the heater control valve. I've got a new one, but there is a port on the top for a vacuum line, but where this line plugs into.
View 1 RepliesGolf IV / Jetta IV :: Vacuum Leak From Brake Booster?
I need replacement vacuum hose part for my GTI 337. The piece that is disconnected is the hose from the break booster to the intake manifold. It appears to be at a one way valve. I found a picture from a different DIY, that I have circled in green. The red arrow points to the place where it separated. I am not sure if this is a matter of me using a new clamp or buying a new piece of hose from advanced auto parts. The vacuum sets on ECS Tuning and it doesn't appear to be the correct set.

View 15 RepliesFord Excursion :: 2001 V10 - Cracked Heater Line - Passenger Side Header Melted
It seems that the install of my Doug Thorley headers didn't go as well as I thought. Turns out the passenger side header melted the bracket holding the heater lines and then punctured one of the lines when it rubbed against the header. Right now I'm not sure what to do. I noticed the melted bracket and pulled the fender well, but that's when I noticed the leak. I guess some of the melted plastic was keeping it from leaking everywhere until I removed it. I live in AZ so the rear heater isn't really necessary so if a stop gap measure is to bypass it then I'm game but I can't find any info on how to do it. If the only real solution is to get the entire line replaced then I'm a bit hosed I guess. 2001 V-10 4x4 BTW.

After finally getting some issues sorted this weekend (needed a transmission flush) I was driving around a bit to make sure everything was good. On the way back to my house, the car started overheating. I replaced the thermostat this winter (~4-5 months ago) because it was stuck open making things run a little cool.
I was thinking the water pump is probably shot but not 100% sure. the radiator fans both work and when I turn on the heater, it blows hot. Any good way to check if the water pump is dead? I have a little point and shoot infrared thermometer and one side of the coolant line was way hot and the other was fine (cold ~90 deg F).
Ford - F150 :: Air Will Switch To Coming Out Of Defrosters When Accelerate - Vacuum Check Valve?
I have a '98 Ford F-150 XLT, 2WD, Short bed, Ext. cab, 4.6L, automatic trans. with 65,000 orig. miles. I bought this truck new. When I have the A/C or heater or just outside air coming in through the dash or floor vents, the air will switch to coming out of the defrosters when I accelerate and then the air will return to it's normal position when I let up on the gas. Is this caused by a bad vacuum check valve and if so where is it located and what does it look like??

I replaced my EGR valve vacuum check valve, but now started getting sputtering/rough idle. I'm pretty sure the direction of the vacuum check valve is correct, but I tried both ways to be sure and still got the sputtering at idle.
The old vacuum check valve didn't give me the sputter. I only replaced it because it was melted and I'm not sure it was working. I included a photo of it. It's orange and black.
GTI 337/20th Anniversary :: 2002 - Check Engine Light Came On / Failed Clutch Vacuum Vent Valve Switch
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.
