Check Engine Light with A/C

I'm looking for a little help with the engine light. I have a 98 V6 convertible and very rarely use the A/C. However, every time I run with the A/C on for over an hour the check engine light comes on and I get the Bank 2 lean mixture error code. A can of injector cleaner in the next tank of gas has fixed it in the past. Could it be as simple as cleaning the injectors and why only when I run the A/C. I would appreciate any help. Thanks.

how many miles are on the car?

The fuel map changes to make more power when the AC is on (it's pretty much what the 87 octane chips run).

So yeah it "could be" injectors . . .

Woe to him who builds his palace by unrighteousness,his upper rooms by injustice,making his countrymen work for nothing...Does it make you a king to have more and more cedar?Did not your father have food and drink?He did what was right and just,so all went well with him. He defended the cause of the poor and needy,and so all went well...But your eyes and your heart are set only on dishonest gain,on shedding innocent blood and on oppression and extortion. Jer 22:13, 15-17
