thats good to know Ray...I knew it affected the timing but wasn't sure how...here is my situation...while cruising 55-75mph (maybe more I don't go much faster than 80) but while cruising and rolling into the throttle heavy to pass or whatever, usually it goes great, nice acceleration, expected performance...sometimes under the same conditions, and maybe only a few minutes later on the same ride, it will feel like it is sluggish, like its retarded on timing...so is the VOES switch something that would be a sporadically ill functioning unit?
