[QUOTE=Jim Villers;1824368]Arthur ..... Bingo! I swapped coil #1 with coil #2 and the problem moved to a malfunction code #22; indicating a misfire of cylinders #2 oand #5 which says that the coil that I moved from position #2 to position #1 is bad.

So, I'll make another parts run tomorrow morning for a coil.

Cool ... I think that could well fit your problem..
These early 104 HFM/SFI had coil problems and the ones that ususally were troublesome were the ones with the Blue sticker on them..most have been changed by now.

Hope that works out.

One can see where a Scope is a nice tool for these full Electronic systems...
I sometimes see those Sun LS2000 DSO's on ebay for short money now [$250]
