Bank 2 STFT acting lazy

A few days ago I made a mistake and spilled some engine degreaser on my vararam filter and it also got on my MAF sensor a little. Cleaned it off as best as I could and everything seem to be fine. I reset my ecm and I been monitoring my fuel trims. I notice bank 2 STFT take about 3 seconds longer to start doing it's thing vs bank 1 every time I let off the throttle then when I initiate the throttle again. Both STFT bank's always used to be instantaneous whenever I get back on throttle. I thought maybe bank 2 o2 sensor might be going bad so I switched them around to see if it would do the same for bank 1 but same thing.

Anyone know what might be happening here?
