Zoltan,

I don't remember this specific one being mentioned before, but there are
many instances in the archives where some faulty connection was causing
intermittent problems rather than the usual FI system components that we
suspect.

For you to be sure that this was the cause of the original problems you
were having, you need to switch back to the original ECU.  If after
running with it for some time without any bucking, then you can be
relatively sure that it was the loose connection that you found.

This loose connection was found when the van stopped completely, a
symptom that you had not experienced before.  So it could be unrelated
to the original bucking and just have happened to occur right after you
fixed the bucking with the 2nd ECU.

Swap the ECU's, drive a few days and let us know what happened.

Sam
