1996 GMC Suburban V8 Two Wheel Drive Automatic
SIRS: THIS GMC HAS A PROBLEM WITH A HIGH RPM ABOUT 1500 WHEN FIRST STARTED. APPLYING THE BRAKE HELPS RETURN THE RPM TO ABOUT 700- 800. DURNIG THIS SUMMER THIS DID NOT OCCUR; HOWEVER, WE ARE HAVING COOLER DAYS AND THE PROBLEM SEEMS TO BE WHEN IT IS COOLER. WHEN THE OUTSIDE TEMPERATURE IS IN THE 80'S AND 90'S THE PROBLEM DOES NOT HAPPEN. IS THERE A TEMP SENSOR THAT NEEDS TO BE CHECKED? OR WHAT? NEED HELP, THANKS
