24- intake air temp signal/ air flow meter 51- a.c. or neutral start switch--- is it a automatic?

the cranks will swap over but there are 2 different ones a 6m and 7m. the 7m is the best its fully ballanced from the 89 to 92 you can tell the difference because the 7m has counter weights (hammers) on every shaft and the 6m is like every other and should have 6m stamped on it.. for the afm bench test it or try cleaning it the air temp sensor is the little probe in front of the v shaped meter when you look in side

my bad use a dry cloth..wipe away the buildup, as for the idle it might be time to have your injectors cleaned and balanced.
