    My 2004 wagon idles rough and has a hesitant start up that clears around 30 mph or so. From that point on, it runs just fine. Have replaced the coils, fuel pump, and fuel filter twice. The previous owner did use regular gas (California) about half the time. If I use the manual mode of the tranny...

    Okay I have a stock 1999 AEB 185,000 miles. The other day it started to cut out more like a fuel mis than electrical like a plug mis. Put my scanner in and also ran vagcom, no codes and short trims -7 to -19 when the problem is happening. O2 looks good when problem is not happening but .750...

    Hi all! So recently I acquired a Unitronic 1+ tune for the old 98' AEB I've got, and I'm getting my first EVER CEL for something other than a misfire. Here's the code: 17545/P1137/004407 - Ross-Tech Wiki Field 32 is showing -14.8% in the "learned idle" portion, and is within spec in the...

    I have no idea what the heck is going on. When i drive, it drives normally, but when i sit in idle, the revs start falling and it runs rich, smokes (smokes probably because its rich) and sometimes it even stalls. This is driving me crazy. I took a video so you guys could see more or less how it...

    I installed the Forge Splitter valve (50/50 set up) last night, and the car ran great this morning, had regular fuel economy (32mpg average on the way to work), picked up boost a little from replacing the leaky dv, but there is a strong exhaust smell now when the windows are cracked or sunroof...

    So I'm getting pretty bad gas mileage on my 1.8T, engine code: AWT. The car has brand new air intake filter, fuel filter, spark plugs, MAF sensor. The turbocharger has been tested for leaks and it was perfectly ok. I am confused by the readings in Group 32 of the meas. blocks in vcds. The...

    My car started running rivh in past few days, more noticeable at idle as it becomes rough when left ticking over. I checked the plugs and they were black I did reset the ecu as I was cleaning my earths, it seemed to start around same time. I believe I should check my fuel trims (032) and...

    I have 1999 VW Passat with 101k miles. The engine has been idling pretty rough after it starts and sometimes the RPMs will be pretty high until I start moving. Once in awhile I'll have a difficult time getting the car started. I'll have to give it some gas. Yesterday it took 8 or 9 tries before...

    More proof that Yahoo's auto articles are terrible. I'm not sure about you but when I see a Kia I don't think "Wow that guy must have a hell of a lot of money." And the fact that Yahoo quoted Jalopnik makes me want to cry. :cry:

    Ok so i have a 01 B5 1.8t passat, For a while i had thought it had been running rich because i could get it to pop back if i rev'd it. Then I got a CEL, went over my Uncles, he read it and we both checked it out (CODE: P0171). After doing some research i knew it would either be vacuum, O2, MAF...
