No, actually, it'll just make it harder for the engine to idle. The injector would have to open and close too fast and instead will be spraying too much fuel. I don't think a small increase in injector size would do that but there's no reason to increase even a little. You'd have to get a ECU retune or standalone to adapt the new injectors to the car (otherwise the ECU would be using the larger injectors like they were the stock ones, and again, you'd be getting way too much fuel dumped in the engine)
If you want to do something with your injectors you can have them rebuilt by Deatsch werks (you should see their ad on the right of the screen, if not, hit refresh until you do . That might help gas mileage because it'll make sure your injectors are working prefectly.
