alright, i was driving my car around the block, and then i popped the hood. the heater core coolant hose had a hole in it, so i duct taped it for temp purposes and ran to the auto store to buy a new hose. i undid the old hose, and put on the new one, and then put some more antifreeze in for the amount that i lost through the punctured hose. i then drive it to the auto store again, to buy a new wiper blade, and on the way there, my temp guage goes all wacky. when im idling, it will slowly rise up. and if im giving it moderate gas, like keeping it below 3k rpm's it will go back to normal. anyone have any suggestions on wtf is going on here? i put coolant/water back in so, that isnt the problem. im thinking it could be the thermostat, but i didnt do anything that would **** it up. also, could it be the heater valve being stuck? ill check that tonite. thx in advance.
