I have the MSD box on my car ,I was woundering if any one could let me know how the two step rev switch works.The light blue wire coming out of the box.
Thanks Geoff
I just fired up my new motor and can,t get my iac to hold a number.It starts at 30 and counts down to ooo and stays there.Any help would be great.
I did check for vac leaks,did not find any.
