4cyl 80 problems

[Alexander van Gerbig]

    Well the OXS is causing that 22mA current most likely.  The ECU is
getting a really lean mixture reading from the OXS, so to compensate the ECU
is sending a 22mA current to the DPR to richen the mixture a lot.  To fix
the OXS problem you may have to get another downpipe, used of course.  I had
this same problem when one of my OXS's came out.  It got stripped and left
all this crap in the threads in the downpipe.  It wasn't that bad so I took
the new OXS and slowly turned it in, backed it up, turned it in, until it
seated all the way.

Good Luck!
