Howdy all,

It's time for my annual hunt for the elusive emissions sticker.  I've had
to get a waiver more years than not, and this year I'd like to cure what
ails the beast once and for all.

What's been done:
New AFC
Compression check (110-120 lbs across the board)
Filters changed before each test (oil and air)
New Plugs
All resistance/voltage values in spec at the ECU connector
All joints and rubber checked for possible air leaks

What's not been done:
Haven't changed the wires

My thinking at this point is to change the head temp sensor, since I
believe the output of the sensor to be low.  If low then the ECU would
create a lean burn state, which is just as hard to solve as over rich.
This van does NOT have an O2 sensor.

Any thoughts on changing the sensor as a final fix, or other's
experiences with similar problems that resulted in a sticker gladly
sought.

Thanks,
Jack
