I have experienced a similar problem =
with one of my 87 Syncro's. Cold start
and run is fine. Problem comes =
when the engine begins to heat up. Too much
fuel when running warm. I =
have switched out the blue temp sensor with a new
one, tried swapping =
computers with one of the other Syncros, put on a
brand-new airflow =
box, idle regulator, idle satbilizer, and switched O2
sensors with a =
"used" one. Nothing has made a difference. I have given =
up
and sent the vehicle to my mechanic, and now he is =
baffled.
He did find the the low (hot) resistance given by the =
new temp sensor was
not dropping quite low enough, but replacing it =
with another new one did
not help either. Monday I should know if a =
new O2 sensor is going to make a
difference.
Any other =
suggestions would be welcome. When we discover a remedy I will
post =
it to the list.
