Hello all,
Long time reader/researcher (est 2010) but new to posting. 99% of the time, thru searching on here I find the perfect fix from all the really helpful people on here and go about my business. This time I am struggling and in need of some help. I am attempting to bring the idle down at a stop and in park neutral to a more reasonable level (750ish rpm)on this crate engine installed in a 72 C10. I have gone thru the idle tuning post and just confused myself even more. Attached is a log file of a short drive to see what i am dealing with. Also attached is the tune file. Any input would be greatly appreciated.
