Subject:      stalling after engine cleaned
Content-Type: text/plain; charset=us-ascii

Cudos to all of you guys who believed that washing my engine somehow
interfered with the 02 sensor.   I was thinking throttle body switch, but
apparently I was wrong.



As you may recall, after I washed my engine, and for a long time thereafter,
when I start the bus and drive away it would stall.  I could turn the
ignition off and restart it and it would be fine for a while, but then do it
again.  Or, I could floor it and it would take off and be fine for a while.
Once the engine warmed up, the problem went away until I started it from
cold again.



So, on the advice of several listmembers, including (if I recall correctly)
Dennis Haynes, Ken Lewis, Sam Walters, and others, I began to focus on the
02 sensor.  I could not find any cracks in the wiring or any defects of any
kind, but when I unplugged the 02 sensor the problem went away.  So this
means that water is invading the system somewhere.  Now where do I look?



My 02 sensor is a Bosch, but one of those that I had to wire into to my old
plug.  I am going to solder the connection and put shrink-tubing on it
(maybe even double up on the shrink stuff).



How long can I run it with the 02 sensor disconnected?  Strangely enough, it
seems to run great with it disconnected, maybe even better than normal.  Why
would this be so?
