K, that's what I thought.
I'm trying to pin point a hesitation/stumble. I was thinking that this CSV could be shorted opn somehow, but I guess not, since the circuit is only energized AS the starter is operating. As I asked in the first post, I wonder what the common failure mode for these is. I suspect its bleeding somehow or maybe I should be looking at some other system.

It's almost as though the car accelerates in stages. and misses when cold at idle.miss gets less noticeable as it warms up, which, in my mind places focus on the WUR. It will do this from zero throttle up to 15-1800 RPM. then it takes off like a rocket..partly because the vehicle hasn't increased in speed enough for the transmission to shift into second gear...
