How can I tell if I just have a gas ping or else the noise is transmission related? 91 w/ the Mazda 5-speed. Noise sounds like small peas rattling in a tin can when accelerating at rpm's over 4000. Doesn't happen when I engage the clutch and rev her, tho.

it's pinging. it doesn't happen with the clutch in cause that takes the load off the motor.

Thanks. Do you think a can of octane booster will fix it.?

cheap and lousy fix. try cleaning your MAS and running some fuel injector cleaner through the tank.
