1993 Volkswagen Passat GLS 2.8L Poor Idle Quality, Misfire, MIL Lamp on
Posted to European Driveability on 10/1/2001 3 Replies

First, Thanks for reading my first post for help! I have done all the basics and cannot find why this Passat is lean at idle. I am leaning toward the MAF sensor but the voltage seems close to other hot wire MAFs I have tested. I could also have an ECM problem....
