I've definitely had the AFM cause cutting out .. though it was just for half a second , just a hiccup. did that for a year or so, just every once in a while at 70 mph or so.

it's good to have a used one or a new or rebuilt one of course. mainly I find they cause 'uneven' acceleration if they're tired.

one thing you can do , or watch for, is a bad spot in an AFM. I've seen two cases where lots of driving at one rpm would wear 'that spot' in the AFM.

like at different throttle openings or rpm it wouldn't do it .. I recently drove 6+ hours right at 4,000 to 4,200 rpm .. in a hurry to get to Sacramento ... then I drove back more slowly. a week later .. if I hit that one rpm for very long ..she hiccups. I could 'drive around' it of course .. and keep it from hiccupping right at that rpm.

what fun this old rigs are ! Scott www.turbovans.com

and hey ....as long as you are never actually stuck or dead in the water, what's a little hiccup or momentary loss of power now and then ? !! ( just joking )
