INTAKE AND EXHAUST DIAGNOSIS
INTRODUCTIONM1151006900321
Intake leaks usually create driveability issues that
are not obviously related to the intake system.
Exhaust leaks or abnormal noise is caused by
cracks, gaskets and fittings, or by exhaust pipe or
muffler damage due to impacts during travel. The
exhaust leaks from these sections and causes the
exhaust noise to increase. There may be cases
when the system contacts the body and vibration
noise is generated.
