Fuel Gauge reads correct & swapping in a diff’ DCV Reg, just for curiosity

 made no diff’ as expected ~

        Current state of functionality of this Van is that it runs pretty well most of the time,

some of the time, ie, it can do significant periods of high speed hiway runs without issue

& then get coughy & chocky on slow down & then the next day do over 200Mi’s of Mountain

driving without even so much as a hiccough & then days with bad times & good times & then

a day of good City Drives only to then a day of Bad ~ When Bad it seems like “Limp Home”

in that On The Fly You can Clutch, turn Igni’Key Off/On, release clutch & all is back to good

for awhile ~

        1 oddity that is a bit of a head scratcher is that during 1 of it’s Bad Phases, If @ Idle

or @ some 10 to 20Ks RPMs it begins to go stumbly & for some reason You decide to reach

for the O2Snsr wire, when Your Hand/Fingers get to very close proximity of the connection

between the wire to the Sensor & the wire to the ECU the Eng will jump in RPM & start to

run smooth again ~ My WAG is some sort of Inducted Signal to the wire from My Electric

Personality but I’m not aware that I have Such ~ Have DVM’d the O2Snsr Wire & Its related

Ground wire & All Looks OK ~~~~  HELP  ~~~~~~
