Stephan,

I'll bet a quart of oil, that your hesitation problem is directly
related to your throttle positioning switch, being out of wack----

Where would I come up with this revolation?

Mine did the exact same thing for months----replaced every switch,
sensor, AFM, filter, plug, wire, and other electrical sundries, and last
but not the least, I got to the TPS, and this was the little bugger
causing the hesitation.

I tossed the old---bought new, adjusted it--- and guess
what------eureka!!!!

The van moved when I hit the throttle.

Try adjusting the TPS first, then replace it if things don't
change---the contacts may be shot.

Later,

            ______________
