Also, the temp gauge has occasionally been showing higher temperatures from the normal 200, it will go up to 215-230 on occasion. The coolant is fine and is not leaking.
The gas gauge also has problems, it will change drastically, going up and down, when I park the car. This hasn't been a problem, and while i think it is just the gas sloshing around when I park, it may be related to idle problem.
I just started to search the site for this problem, but any help is appreciated.
