Hopefully it is a simple answer.  I just changed the oil, added a can of Sea
Foam to a full tank of gas, and removed the instrument cluster to pull the
Speedometer so I can send it in for repair.

I left the entire instrument cluster out, and drove it back the our friends
for winter storage.

The van kept stalling at idle, and doesn't seem to have the power it had
before.

Could this be due to the instrument cluster / tachometer not being
connected?

Thanks,
