the normal thing to check or think about in a case like this is Temp
Sensor II ..
there are two by your thermostat ..
a single contact for the gauge ..
the other one ...check the resistance of that one and compare that to
what Bentley says.
also ..super important and I find them off all the time..
idle switch not making contact at idle.
you might look for tiny air leaks ..( like with spray carb cleaner or a
listening hose ).
I had one engine that
when given throttle it would moan like air was being drawn in ..
and it ran medium OK ..
but it seemed very much like it was not getting the fuel injected to go
with the air.
on that one I found really ..at least 10 tiny air leaks at the intake
runners..the plenum ..and the throttle body connection
and that was it.
do these 3 things and there's a fair chance you'll find some some
things not exactly right.
