[Eric Mathews]

GAAHHH i hate cars!! lol now that i got that out of my system ok well my temp gauge is freaking out! it says my engine is over heating, but its not hot... sssoo i change the temp sensor, it seems ok at frist staying in the middle and then all of the sudden it pinned on hot? just out of no ware, not like slowly it just jumpes... then i pull over and check the rad temp and its cold and the rad hose is hot so there is hot water going through.... then i keep driveing and it then goes back to the middle?? so i change the thermostat and it does the same thing still... but now it just stays on HOT,  but it still just all of the sudden "overheats" but its not actually running hot.... what else is there to do? is my guage freaking screwed? or is there anything else it could be?  HELP!!!

Eric, there are 2 of em, very similar location.  One is for your ECU and one is for your gauge.
