2003 Chevrolet Suburban 1500 LS 4WD 4dr SUV (5.3L 8cyl 4A)
After hot engine shut down vehicle has
loud and prounced bangs coming from
exhaust system. During cold start up a
loud and prounced poping noise is heard
from the exhaust system. When vehicle
is driven at highway speeds of 60 and
above the droning noise in the cabin is
prounced and over powering.
I believe GM has a definite problem
with the exhauts systems on the 2003
suburbans. There is a bulitan out
concerning the poping noise. GM has a
superfical fix? for it. HA?
