I was just driving along running fine then suddenly no power, I tried to
crawl along but engine got hot!!
It will fire up when cold... then run poor quick..
It just fixed it last week.. bad ground. ran fine for week...

I suspect bad AFW  measured pins 6 and 17 at ECU harness and pin 3 & 4 at
AFM  554 ohms  pins 17 &21 at ECU harness and pins 2 & 4 at AFM ohms change
as flaps moves  but pins 6 & 9 at ECU harness and 1 & 4 at AFM  show 1514
ohms @ 68 degrees...  doesn't seem right...

will bad temp sensor 1  cause this?   if any body has a spare I could borow
to check my AFM i'lln pay shipping / to / returm
I have a 1991 Vanagon  but guess any 86-91 will do

My part # is 025-906-301C
