Well ,no real good guesses , Jon .
I do know that I had an 86 Shelby Charger Turbo that all the sudden didn't
wanna start .It would crank all day long , but not start . It ended up
being the Idle Air Speed Control Valve . Took me 3 months to figure that
one out !
It almost sounds like a timing issue the way it does it at certain RPM .
I dunno , that one is gonna be one of those ones that just pisses ya off
for a few months till you find it .
Good luck !
