:ack: O.K. I've been all thru this thread & the 2.5 gauge pod swap one as well ....I swapped a 89 Eliminator pod into my 90 2.5 ax4 2wd .I knew the reading was off by about 1/3 ,idle varies between 700-1000 , although it sounded faster . Sooo I tried the adjustment suggesting "turn screw full left for 4 cyl. ".......WRONG :headpop:( idle now reads under 500 ) Pull the whole freekin' pod apart again , try turning screw full right ( idle now at 1250-1300 ) Have no idea if thats correct ? Of coarse , I never bothered to calibrate with a hand-held tach for reference :dunce: ( when I worked for the O.K. Ranch , cowboss Al would always tell me a Short-cut was the longest way anywhere )....The delema now is ,if the reading IS correct , what do I do to get the idle to a reasonable range ? :hmm:
