Popping Idle not pinging

[Noel]

so I live in calgary alberta and drove the 12 hour straight drive to vancouver because im going to school soon. ANYways ever since getting into BC ive been filling it up with 94 instead of the 91 i always get back home. Now my car is really boggy in low rpms and when idling its making a popping noise every once and awhile and just idling brutal like there isnt enough o2 mixing w/ the fuel ( vac leak air leak something like that ) My AFR when idling is off the charts bad its not even registering 18+ when should be at 145-150 and back and forth. I checked all my couplers and they appear fine ( visual ) and my vac lines aswell. my bov however was stuck partially open which is weird its pretty much new so i took that off and fixed it. however since doing that now im flipping a cel and its still idling like garbage.

I cant think of anything else to do and its killing me I need my vehicle to get to school which starts tuesday! any suggestions..

what does the "CEL" say? if its P0300 and/or P0401, it's the EGR valve.... it is covered under warranty still, regardless of mileage

Some of the Husky and Mohawk gas stations sell 94 octane in Calgary if you want to test the gas theory.
