Hey guys, i did replace my temp sender for the the gauge a while ago, and its starting to act funny. Like once to comes up to temp it reads different depending on what is on. I can turn my blinker on and it will move in sync to the blinking light. Also turning the headlights or fan on same deal, moves it out closer to the hotter side. I guess its a bad ground? The main ground cable is new, Should i just clean all of the grounds i see under the hood? I was also making a trip and I could have sworn the motor cut out for a split second a few times, always recovered and ran perfect. The temp gauge also fluctuates from normal to hot, which is weird. It does run fine though otherwise. Any ideas? I was going to start cleaning grounds on monday when i have off. I am kinda stumped.
 
did you put a lot of teflon tape on the
sensor? that can mess up the ground.
