literally no one will know whats going on since you provided 0 details. "having problems" is so generic. for all we know, there could be 2 squirrels having sex in your engine bay and that is the problem....

I'm sorry! Okay so when it idles it will randomly drop to like 200 rpm then come right back up and that's the only time it gives me problems.

Based upon the info: water is heavier than fuel and settles to the tanks bottom. Either being low OR the NEW fuel has water in it which doesn't burn well. It could have sucked up that water and other debris from the tanks bottom which is effecting the idle and you don't notice this at higher RPMs.

Because our oxygenated fuels inherently pull in moisture (methanol attracts water), I'd suggest some fuel treatment aimed at removing water. Fill it full and go for long drive on twisted road to get the water to mix and burn.

FWIW: every 4 months or so dump a bottle of Chevron Techron in there to clean the fuel system up.
