Weird engine idle

[Faze]

Parked in Plaza and after few minutes I noticed the idle is up and down, went to performance pages and see what the gauges show. Does this happen to yours too? AC running, fan at 2 or 3

Mine is at 940 miles. I have not experienced that type of idle even with AC on. Mine typically hovers at -15 in Hg with maybe +- 1. Did the RPM fluctuate too?

yes RPM goes up and down, it's noticeable that's why I looked for the gauges, it doesn't happen immediately either, only if i'm sitting for like more than 10 minutes

Bad gas??

What happens when you run it with the A/C off?
