Why would you want a break from cycling? Rider and road in harmony. Especially in winter, I do mean that seriously. Deep joy.
You seem to know a lot mre than me about the 240. But it sounds a litle like MAF. How are the code reader results and other tests? Can you borrow a known good MAF for a while? Please don't buy a new ne unless sure of needing it.
Good luck.
You do have winter cycling boots? And mittens?
