I changed out the opti the other day and it got kind of better but its still there. Im maybe thinking a spark plug that might have been gapped wrong. I might go out on a limb and say the O2's but I havent scanned it for codes. What else might it be??

A while back my car was missing at idle and it turned out the shop that installed my spark plugs had one of them gapped at .2 I'd check your plugs, wires, and coil.
