1999 Chevrolet Express 3500 5.7L Hesitation, Surge, harsh/no shift
Posted to GM Driveability on 5/10/2007 7 Replies

Scan normal except for VSS. Seemed like classic bad sensor. Replaced sensor - no change. Truck is almost undrivable. ECM doesn't know what to do with [...] at idle. Will go normal for a second when the engine shifts (rolls). Acts like a chaffed or cut harness....
