Donnie,

Ok, I think I know where the decel swithch is,(small roller switch near the throttle linkage)or is that the throttle cuttoff. Ok, I'm stumped how do I check these? I was sorta convinced that it was the aux air/idle valve sticking then slamming open then shutting etc. I sure don't need to buy one for &150 if I don't need to. So how can I check those other sensors??

Thanks alot
