This is on my 10th AE. My temperature and gas gauge go all the way up when it is cold in the morning until my car warms up then they go back down to reading fine. This only happens when it is pretty cold out. My Rtek reads that the temps are fine, so i'm not worried but I would like to fix the problem. I searched but couldn't find any similar symptoms. Thanks.

 

mine does the same thing so i am curios as well

 

Try taking the sensor off the motor and cleaning it out. Could be a very possible issue. My oil pressure gauge did the same thing until I cleaned it, now it works perfect.

Make sure the post it connects to and the connector are clean.
