2005 Chevrolet Silverado 2500 HD 6.6L Hesitation, Surge
Posted to GM Driveability on 6/15/2009 4 Replies

this vehicle looses power and falls on its face on heavy acceleration. sometimes at slower speeds but all the time at speeds around 80mph if you accelerate hard. the boost psi drops down from around 30 to about 5. no codes. i am trying to check the fuel system...
