ok guys i checked out the temp , with a infrared thermometer and the temp reads very close to the gaug, so it;s not the wiring harness, i checked the temp on the RAD and it seemed the top left corner of the rad was hotter then the other parts of the rad but i think thats normal since the upper rad hose gets hooked up on that corner. the car is running hot at about 100-120c but the coolant isnt overflowing, no signs of coolant in the oil, checked the oil cap for signs none, and none in the oil. Yesterday when i turned the car on, i ran it at idle for a good 45mints and the temp went up for 100-120c then i sat in the the car and held the gas and cranked the hearter on full blast and the temp went down to 80-90c. im not sure what;s going on with this car, also the car idles up and down somtimes, i dont thinks thats related to the overheating issue.

thanx for your help guys.
