I noticed today that the engine temp doesnt stay steady but it never over heats... Range from 80 when moving to what I would guess is 90-95 when at a stop for a while. Time for a new thermostat?

Its weird that you say that because I didnt notice it come on until it was already running hot... What would cause this?

If the fans are not coming on I would check the fuses.
If they come on late or intermintent might be issue with temp sensors
If it has been a while replace the thermostat, do coolant flush

At what temp should the fans come on, because they are popping on at about 100-115??? I don't want to buy the wrong temp sensor either... Is it the coolant temp senor or some thing else?

check number 3 fuse I think it is. Mine usually turn in within a minute of turning on my ac. However, my temp rises between 80-110 depending on if i ma driving or sitting. If I wait in a drive thru for food, it gets too hot and I have to rev the engine to cool it down.
