Report: Worn Valve Seats May Cause Engine Misfire
Chevrolet Tahoe Problem
Model Years Affected: 1996, 1997, 1998, 1999, 2000
Engine Affected: 5.7L V8
The engine may develop a misfire due to worn valve seats. This fault will cause the Check Engine Light to illuminate. Our technicians tell us the misfire may or may not be felt while driving. They further recommend that both cylinder heads be removed and thoroughly inspected and repaired as necessary.
Engine Light on constantly. Codes Read at Auto Zone: P0449 EVAP purge/vent solenoid circuit condition. Is this a dealer only part?
