Default 2002 I35/Maxima ... P0021 and flashing SES (misfire?)

I've got a 2002 I35 with 126k miles.

I've had the P0021 code for about 6 months but I haven't had it fixed because the car was running well enough. I believe I just need to order the front IVT sensor for about $150 but I've been putting it off.

During the last 2 weeks, while it has been very cold, the car sometimes has a rough idle. Yesterday, while accelerating, the SES light starting flashing and that appears to be a misfire based on some preliminary Google research.

Could the misfire & P0021 be related? I just had to replace a front hub and wheel bearing for $475 so I'm hoping this misfire is going to be an affordable repair. Please advise.
