The weather here in New York just turned frigid, and today after I wamed my
85 Chevy S 10 up for 10 minutes it shut off after it warmed up...... if I
kept my foot on the gas it would run but as soon as I tried to let it idle
on its own, the engine died....... I have a feeling that it is a choke
problem, please tell me specifically what to look for and how to fix
it....... up until today, the truck has run fine......
The choke might be sticking closed. In your driveway or garage, from a dead
cold start, fire up the truck. Remove the air cleaner once it's started and
watch the choke plate. If it stays shut, it's either bad electric choke
element, bad vacuum line to the choke pull-off, no +12V signal to the
electric choke or a mechanical choke linkage problem.
If the choke opens fine and it's dying, it's likely not getting enough gas.
I'd check fuel filter and fuel pump first in that instance.
