05 Grand Prix Temp Sensor Off and Rough Warm Start
05 3.8, 160000 miles. After sitting for an especially
cold 4 day weekend, it started a little rough
(understandable) and then when I stopped for gas it
wouldn’t start again without giving it gas. At this
point I noticed that the temp sensor did the usual
ramp up at starting but then went back to off once
the car was running. After work, it started normal
but I restarted once I got home and it needed the
gas pedal to start again. The radiator fans came on
immediately upon restarting. Outdoor temps range
from -10 to +15 F here.
