  1. Thanks, Loren. This code did occur after allowing the car to idle for 5-7 mins after driving, Weather was warm, about 70 but no humidity. (NY). Any easy way for me to further investigate this? I have a simple code reader. Do I need Durametics? After clearing the code, the car seems to be running fine. However, I do have some hesitations at cold idle and part (or very lite) throttle and believe this is normal for a flashed ECU. However, this code has never occured and it does worry me. Is there an easy way to further diagnose this issue?
  2. I have a 2001 tiptronic car with larger turbos, exhaust, flash. After a drive today, a CEL came on and its codes P0171 & P0174. Banks 1 & 2 are too lean. I have no idea why this occured. It happened after letting the car idle for about 5 min after a good, hard drive. Any help would be appreciated.
