06 avalanche exhaust clunk
I have an 06 avalanche that just started making a
clunking noise appears to be coming from the
exhaust between the manifold and resinator or
catalytic converter . When i give it a little gas the
noise stops then starts back up when it returns to
an idle. Any odeas on what it may be ? Thought
maybe a broken 02sensor but the dummy light isnt
on maybe the internals of the cat. Or resinator are
loose?
