The dash (electronic) gauge on this truck goes nuts when the truck is started and just begins to get warm. Like, from stone-cold to about 3 minutes of idling. The gauge will peg-out immediately. I know the sender is probably bad, but here's my dilemma...there is a sensor in the coolant stream next to the thermostat. Disconnecting this sensor does not affect the dash gauge, but does make the engine run crappy. There is another sensor between the sparkplugs on the passenger side of the truck that seems to be the sender for the dash gauge, that is, disconnecting it will cause the guage to fall to 0...but that spot is where you would usually find a knock sensor. Any GMC pros out there that can tell me for sure this is the sensor for the dash guage? I'm not a car mech but not stupid either...we are in a budget crunch and I'm trying to save a buck or two.Thanks.
