2001 Chevrolet Express 3500 Problems

Engine Misfire Due to Worn Valve Seat

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.

Check Engine Light and Misfire Due to One or More Stuck Closed Fuel Injectors

One or more fuel injectors may become stuck closed causing an engine misfire  and the Check Engine Light to illuminate. Our technicians tell us that this problem can be caused by some fuel additives. There are special procedures which may be able to restore the affected injector. If this fails the affected injector must be replaced.

Replace spark plugs every 100,000 miles

The spark plugs should be replaced every 100,000 miles. Our technicians recommend replacing the spark plug wires also at this time.

I live in Bonaire and did buy this Van in Aruba .The cooling Van is a little bit noizy and there`s to much sensors around the engine 4 oxigen sensors, cooling temp sensor, trottle pos.sensor, crankshaft position sensor etc etc. If 1 doen not work properly you will loose power in your engine or the transmishon will not shift properly.
