Its been about a week, my engine makes a constant clicking noise when I'm at a red light idling or parked after driving around for about 10 minutes.
Can this be because of the gas I'm using? Since GA is out of gas, I was forced to put in regular gas for the past 2 weeks.

youre not the only one. mines has gotten loudier than it was a couple of months ago..

 

lol, this noise is starting to annoy me. i'm bringing it to the dealer in an hour to have them check it out.

 

If the ticking increases with the eng RPM it is the heater core. there is a TSB.
