    Default Temp guage acting wierd

    Hello Guys

    1GGTE

    My temp Guage would go to halfway on the digidash then all of a sudden up to HOT......
    at 1st i thought it was the temp sensor so i swapped in a working one still had problems...so i cleaned out radiator changed coolent...then i found out by accident when i unplug the OXY sensor the temp goes immdiatly to halfway....now what the hell is causing that for now ive left the oxy senso disconnected....also the car doesnt run hot at all...top hose is hot and bottom hose is coolish...

    cheers
