Tech Tips
Ping
PING, PING, PING
Does your 1990-1992 300ZX make a pinging or ringing noise while driving in 5th gear? Have you checked all of the usual suspects; ignition timing, EGR operation, gasoline octane rating, etc., and found everything operating normally? You may need a reverse gear countermeasure kit (part number 32220-30P26). Installation of this kit requires that the gearbox be removed from the car and disassembled so be very, very sure of your diagnosis!
