1992 Chevrolet S10 Blazer ProblemsEGR Valve Stuck Open Due to Carbon Stuck in Valve
4.3L V6 multi-port FI only
The exhaust gas recirculation valve (EGR) may stick open causing a rough idle and the Check Engine Light to illuminate. Our technicians tell us that a piece of carbon may become stuck in the valve causing this problem. Cleaning the valve will usually correct this condition, in some rare cases the valve will need to be replaced.
The heater core under the right side of the dashboard may leak engine coolant which can puddle on the passenger front floor. The loss of coolant may cause an engine overheating condition. Our technicians tell us that removal of the dash board is necessary to replace the heater on these vehicles.
