Hello and welcome to Justanswer!

If the engine is overfueling just a couple cylinders it would usually be an injector related issue. You may have injector issues on those cylinders or the injector driver circuits may be shorted on. Shorted injector driver circuits could be a wiring problem or internal issue in the engine controller.

How did you determine these cylinders are over fueling?

Has spark been tested on those cylinders?
