Hi everyone,
I have this weird problem with my temperature needle/gauge. Whenever I speed up 70mph and above my tempt needle/gauge suddenly begins to drop sharply to the cold mark in a matter of a second. When I let of the gas or drive below 70mph the needle suddenly returns to normal. Car blows hot air throughout this entire episode and the needle never goes up above normal/overheats. This just started this winter. I have checked and bled air out, checked for leaks, and changed the thermostat but to no avail. Any ideas what could be causing this weird problem? Shouldn't tempt go up at higher speeds and not down? I'm kinda confused:( . Thanks Eli This post has been edited by malecrod: Dec 22, 2006 - 8:02 PM -------------------- 3sgteing.

no its not. the coolant temp sensor with the green plug that faces the front of the car is only for the ecu. you want to replace the one fhats on the other side of that coolant neck. the one that faces the driver.

Thanks Lagos, that's exactly what my problem was. The connection to that sensor was loose and I guess vibration at some speeds causes to not make contact and hence the drop in tempt needle. Once again thank you. -------------------- 3sgteing.
