Just looking to see where the best place to start is..

I have returned the car back to the stock tune with just a Corsa sport exhaust, the car did use to run e85 for reference.

The car will semi-regularly drop RPM's only when sitting still and bog a little but an recover 99% of the time. Occasionally the car will die but fires right back up. The car runs smooth through the entire powerband and while moving as a reference. There are also no check engine lights/codes.

The vehicle has 37k miles and just looking at the best places to start (spark plugs, O2's, exhaust leak maybe?). With the car running E85 I am leaning towards O2's from research of those getting clogged up pretty quick.

Appreciate any help in advance.
