GTI 337/20th Anniversary :: Car Sputters Around Half Throttle / 10 PSI
Yesterday, I was taking off from a light and noticed that when I got around 10 PSI, the car kind of nosed over and sputtered. So I started to play around and discovered that no matter what gear, this always happened between 7-12 PSI of boost. Normal driving for me is shifting around 3k RPM, about half throttle. Sometimes when I shift, it pops. Not like a normal, chipped car pop but not quite loud enough to be a backfire.
I took my dad out in the car and got to 55 MPH, then held the throttle half way to keep boost around 10 PSI and it would start sputtering/bogging down erratically. Any more then 12, and the car is fine. Any less then 7 and the car is fine. He suggested a Throttle Position Sensor that has a dead spot in it.
Here's some thought from me:
Coils/Misfires - If it were a coil or misfiring, it would be all the time, not just what I described above, correct?
Boost Leak - At WOT, the car gets up and goes while holding steady boost.
Vac Leak - I've been told at idle, the car is supposed to have 19-21 in Hg of vacuum. It's at 20.
If you turn your speakers up, you can actually hear the exhaust gurgling in the video when I hit the spot I am talking about. There are no loud noises, so don't worry about maxing them. I had to.

GTI 337/20th Anniversary :: Clutch Pressure Low - When Pushed Only Come Back Up Half The Way
Started losing pressure on my clutch pedal yesterday. When I would push in the clutch pedal it would not push back up to the reset position. It would only come back up half the way. Now today I have a steady ABS light and ASR light on. Checked for fault codes and found no trouble code. Checked brake fluid resevoir for leaks; still has plenty of fluid. Checked slave cylinder bleeder valve for leaks and looks dry. The only thing I think it could be is the clutch master cylinder. If I drive the car for a few minutes I am able to build pressure back up in the clutch, however the ABS light and ASR light still remain while driving. Turning the car off and back on again shuts off the light for a few minutes until I start driving, but the clutch pressure starts back low again.

I have a 04' Jetta 1.8T (AWP) my mods are APR Chip (91octane program) Forge 007 DV, APR TIP, NGK spark plugs, catback exhaust. This issue I am having pretty much started when i got it chipped and I've got it reflashed and I've even talked to people at APR and they are saying that it couldn't be a software issue. Anyhow the problem I am having is at partial throttle my car kind of hesitates a little at 5psi and when i let of the gas the car kind of hiccups a little.. but if i really punch it in every gear i hit 21-22psi no problem, the problem happens when I am driving normal and its really annoying.
I have switched several different N75 valves, I am running the stock one now, I've switched different DV's, i have switched my spark plugs and even put at APR turbo inlet pipe and i have checked for boost/vacuum leaks, I have no CEL...all this hasn't resolved my problem.. I don't know what else to do..
I was thinking about switching my MAF to see if it works, but then again if it was my MAF im sure I would have a CEL. I also was thinking about putting my N75 valve backwards even the DV backwards to see if it works?
GTI 337/20th Anniversary :: Radiator Malfunction - Hot On The Top Half And Cool At The Bottom
So basically a couple months ago I picked up a 03 20th and GTI, I love the thing to pieces, recently I've got into drive it and I can watch my temp gauge steadily climb to 90 and stop. (before I go any further, I haven't gotten any overheat warnings or anything like that, I've just noticed my car is really hot all the time and the temp gauge goes to 90 within a minute or so of driving but doesn't go over). heat works fine, I've gone in the engine and tested a few things, tested the fans by jumping the connections, my large fan is dead but the small works fine. to my understanding, the large fan isn't used much unless it's really hot anyway. so I removed it and continued trying to find my problem, I felt the rad after letting the car run for a bit, the top half was hot but the bottom half was cool, took the hoses off and flushed my rad thinking maybe something was clogging it, water ran through fine, so I put it back together, put new coolant and tried again. same thing. so I took it for a rip and came back, obviously, the top hose and the rad were hot, but the bottom one was kinda warm. I looked for answers online but I can't seem to find anything like what I'm dealing with. the water pump seems to be working fine, I'm not sure how much flow is supposed to be coming through the Small hose at the top of the reservoir, But I checked it and it has a steady stream coming out of it. I've worked all the air out of the lines as well. The car isn't overheating and doesn't really pass the 90 mark, fans almost never come on but the small one kicks into low when I turn the AC on. which as far as I'm aware is what's supposed to happen.
The car feels like its running hot, checked everything I can think of. rad is hot on the top half and cools at the bottom, coolant has a steady flow back to the reservoir. no actual overheat warnings, I'm just wondering if these cars run hot normally or if I should be concerned.

The car is a 2004.5 GLI 1.8t. My car threw a CEL about two weeks ago. When i ran the codes it had one for the camshaft position sensor, one for the secondary air injection, and one for the camshaft position sensor. I cleared all the codes and the light came back on. The only code that came back was the camshaft position sensor P0340 i believe. I drove the car for a week and out of nowhere it just shut off on me while driving.
All the lights on my dashboard were flashing (traction control, battery light, engine light, etc.) I tried to jump it just to see if it would turn over and still nothing. I rolled it down a small hill and tryed to pop start it...still nothing. So I had it towed to my house and I replaced the cam position sensor AND the crankshaft position just to be safe. but now the car still won't start...
The engine is cranking and you can hear the pistons moving but it just can't get the juice to start. After failing to start it 3 times, i noticed a loud vacuum like noise coming from the engine when i turned the key off...but my car would do that every other morning when it actually started and didn't have the CEL, and then once it warmed up the sound would go away.

Last night was the 1st night my car spent OUTSIDE the garage and it POURED! Anyhow, the door ajar symbol is lit in my instrument cluster but all the doors are shut. I did the walk around, made sure all the doors and hatch are closed. The symbol would disappear for a minute then reappear. Whats up with that? I never came across a problem like that.. Where are the sensors so I can check them? Are they the little things that stick out underneath the door?

GTI 337/20th Anniversary :: Downpipe Installed / Car Started Rattle
I just installed a brand new 42DD downpipe in my car about two weeks back. About a week later, I started noticing a rattle that I hadn't heard before, coming from the undercarriage, about mid way back, where I assumed the downpipe is. I only hear the rattle at low RPMs, like 1000-1500 revs, when I pull away from a light. I can stop the rattle by giving it more gas before letting the clutch all the way out, but if it's something I can easily fix myself, I'd rather just do it.
I searched some DIYs and found this. [URL]..................................... I bought new sets of stage 1 dogbone mounts that I need to put in soon, probably next week when I'm on break, if that will remedy it.
GTI 337/20th Anniversary :: Loud Noise / Vibration As Soon As Car Started
I have an 04.5 jetta gli ... Mods are unitronice stage 2, eurojet tb exhaust, cold air intake, diverter valve, nothing else really.
So, whenever I'm driving alone my car is fine. But once I have a really heavy person in my car, or maybe 2 people in it, as soon as I start the car I hear a vibration. It sounds as though it could be my exhaust? Because before I had it installed months ago it would never do this.
Also, as I accelerate I feel and hear that it is bogging like my car is struggling to go fast and i do see some signs of loss of power. So is it the exhaust?

X2 nights ago at 11:45pm I was driving home from a friends house with my gf and were going about 65 on the highway and it's lightly raining, then all of a sudden my headlights, windsheld wipers, turnsignals, my ac/fans all just shut off so I had to pull over right away. After sitting there for about 15 mintues I figure out my high beams still work but only if I hold them on(clicking it on doesn't work. So I drive home and the next day check all the fuses in the drivers door and they r all fine. Everything else works in the car but the stuff stated above. My car was reposesd about a year ago when I lost my job and they put this thing I have to enter a code every month, it messed my windsheld wipers and turn signals up before but not anything else! But it still works and the other stuff doesn't, and behind the dash it sounded like crackling and smelt like burning electric right before it shut off.

1997 Ford F-150 4.2L V6... I got into my truck yesterday and went to turn it on. The motor cranked half way then quit. Now everyone time I attempt to turn it on all I hear is a click and nothing else. A friend of mine who is pretty good with cars took a look at it with me. He tested my starter with a volt meter and said everything seems fine. We proceeded and checked all fuses, non of which we found are blown.
We then focused on the starter solenoid. We were able to get the truck running by arcing the 2 lower big terminals. I purchased a new solenoid thinking that was the problem, however replacing it solved nothing. Same problem is still present.
I have now arc the terminals to get the truck started 2-3 times in order to get to a shop. They spent all day looking things over and are pointing the problem to a bad starter relay. (i thought the starter relay was actually the same thing as the starter solenoid) Anyways they told us they have looked over all the diagrams they have access to and cannot locate the location of the starter relay. (maybe becasue its the solenoid?..)
