1991 Chevrolet Corvette ZR-1 Problems

Replace spark plugs every 30,000 miles

The spark plugs should be replaced every 30,000 miles and the spark plug boots should be checked for hot spots and cracks.

Service transmission every 30,000 miles

Our technicians highly recommend that the transmission is serviced every 30,000 miles to avoid problems and maintain optimal operating order. If the fluid is dark in color, the transmission should be flushed.

Car Won't Start and Security Light is On

Problems with anti-theft systems using the raised-chip key can prevent the car from starting. The wires in the steering column to the ignition lock cylinder tend to break. The key and ignition lock cylinder should be replaced to correct this condition.
