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 --- john cianci <jcessence@HOTMAIL.COM> wrote: <HR> <html><div style='background-color:'><DIV></DIV> <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.
