The plugs are OEM plugs Part#004-159-14-03. I also had the voltage transformer rebuild. The car did ok for about a week then started the misfire again. Thinking about putting on a new voltage transformer. running out of options.

Looks like your voltage transformer gave up again after being rebuilt. I would advise getting a new one, since one whole bank of cylinders misfiring usually indicates a voltage transformer problem.

has a voltage transformer rental program to make sure that's what it is
you can either keep theirs if it works for you or send it back and buy new if you want new

Don't think the issue is with the VT as it has been rebuilt. Wiring problems would caused the exact same errors.

This is very interesting... half my engine decided to go out today... again... for the 5th time... and this time it seems to be symptoms of a voltage transformer issue. Half the engine went out randomly while driving under normal conditions.
My voltage transformer went out a little over a year ago, and I got it rebuilt/repaired instead of getting a new one. Looks like the plastic casing on the old part number for the voltage transformer 00 150 01 58 is prone to the heat of the engine since it sits directly on top of it, and causes it to go bad often. However, with the newer redesigned voltage transformer with the part number 000 150 02 58 the casing seems to be made out of heat-resistant material and should be more reliable.
I'll also keep this thread updated on my own random and disappointing trip down the misfiring memory lane again...
