I am so sorry - i should have said "...and APPEAR after driving for a while..." This is because the O@ sensor is ignored by the ECU until its signal "makes sense" to the ECU, but it may not be the right signal for conditions...

But, they don't go away after awhile, they might not get worse, but they are
certainly persistant and not going away. Also, should there be some kind of
splash guards on the sides?s

IF these symptoms arose AFTER the van got wet, AND go away AFTER running
awhile, the O2 sensor is a suspect. Unplug the sensor wire, and try the same
driving course, to try to duplicate the problem...

running great since the rebuild but now (last three
days) has developed a hesitation. It drives fine in town but when I try to
get on it to get up to highway speed in 3rd or 4th it bogs way down and if I
don't lift seems as though it would die all they way. If I lift my foot and
slow a bit and down shift it seems fine again until the instant I try to
speed up again. Happening right around 4000 rpm on the tach. Plugged cat
maybe? I took some connections apart and cleaned them with elec. Cleaner in
a spray can. Even unplugged the ecu and plugged it back in. I did this all
this morning before starting the van. When I started it and warmed it up I
took it for a test drive. Was fine for about three miles and then started
it again. We've had a ton of snow and slush last week so I think something
got wet. Maybe the water causing the problem was frozen this morning (25
degrees F) and didn't cause a problem until thawing out. Also, am I
supposed to have and splash guards around the engine? Seems to be hole to
mount some on both side in the wheel wells.
