Hey Ross,

	Actually, if it was like my 1978 Nova it might have come in handy,  I
was adjusting the engine timing a couple of months ago abnd I actually
had pinging durring idle.  I wonder how it would work then??  Of course
if my Nova had a computer I wouldn't have to adjust the engine timing.  
;)
