RE: Surge at idle and miss above 4k.....

Not in front of a diagram, but the no start and no heater/wipers sounds
like a description of a failing ign switch. Maybe multiple problems.

I've got a wide band installed but not hooked up yet. I need to mod the
link ecu for wide band when I get home. I had a situation where I could
not start and no blower and wipers didn't work. Then while driving on
the highway it all started working again.....hence my ground problem
diagnosis.
