Hi John:

I had a similar problem last spring...my 1990 was with
a mechanic who knows VW's inside-out...and no matter
what he did it ran rich. Listies kept stressing a bad
ground...an finally I held him at gunpoint ;-) and
made him check EVERY wire and ground...and sure
enough...it turned out to be a sneaky bad ground.
Go over each and every possible ground....
Good Luck,
Kevin

<DIV></DIV>OK, you guys have been a lot of help so
far. but my bus is still running way rich and puffing
black smoke....so far...new ecu, temp sensor, grounds,
o2 sensor, cat, idle stabilizer.......checked: hall
sender, distributor, lots and lots... BUT THE BUS
STILL RUNS RICH....heres the weird thing....The bus is
at a good mechanic in the area ( I have heard a lot of
good things) and when he unplugs the MAF, the bus
contrinues to run (shitty, but runs). The bus should
stall , correct? Well, it doesn't. Does anyone have
any more idea, I am going to go search the archives
and see if I can come up with anything. Thanks a lot.
