[V8] Cold Weather Sensors

[Bill Hitzler]

My 1990 is an early run that doesn't get info from the coolant sensor
behind the passenger side. Which other sensors give the ECU temperature
related info. The car starts fine and runs great until I stop at a
traffic light. Then the torque converter gets balky as I let off the
throttle and it also runs richer. The car does this when it's 40 degrees
or colder and only after I stop at a traffic light. It will happen
whether I've driven 3 miles or 13 miles; BUT ONLY AFTER I STOP FOR A
LIGHT. I've pulled codes when it's happening but don't get anything.
I've adjusted the multi function switch for the tranny all to no avail.
I'm thinking one of the sensors might be marginal. It's been a pretty
good head scratcher for me. The car remains very driveable through all
this but it's become a personal challenge to track this little gremlin
down and exterminate with extreme prejudice. Any thoughts ? Thanks,
William
