Default 2007 maxima engine problems

I have a 2007 maxima se. About a month ago, I noticed my check engine light on. Next I noticed the car idling around 1100 rpm, which is high. Next my gas mileage went to crap, and the car has no balls whatsoever anymore. My mechanic put the computer on the car and the po300 code came up. We've tried plugs, coils, and replaced 3 injectors. The cars still running like crap. My mechanics stumped. Please tell me someone else has experience any of this and knows wtfs going on with this car.
