No one asked about the octane of gas..better be 93 or higher(USA) granted i know CA has 91 the octane also varies gas mileage..biggest thing I read was the idle time warm up its nothing like your 79'; turn it on wait for the idle drop or a good 30sec and go off just no hard pulls until engine is fully warmed up good luck! By the way mine idles at 600 which I feel is completely to low as it dips below 500 when the light or blower go off I know of the tsb
