This hasn't really posed a big threat to me or anything, but it does bother me when i drive around. I'll start out with the 1 bar usually. Start driving around a bit, and i get the 3 bars where it normally stays. After driving around awhile usually taking a few turns or something it'll drop back down to 1 bar. My s2k doesnt act weird or anything when it happens so i'm assuming mabye a bad sensor somewhere or something. Anyone else have this problem?

 

I'm not to sure, mine only starts at 1 for a few minutes. After driving i'm at 3 all the time.

 

Are you stock?

that is not normal, could be the thermostat is stuck open, but it should NEVER go back to 1 bar from 3 unless it been off for a few hours

 

Nope, never seen this. Would guess bad sensor or stuck thermostat like was mentioned.
