Get your EGR valve cleaned my 2.2 displayed various power issues till it went into totally flat power output. If that's ok could be failing injectors or just a dirty air filter just eliminate as many things you can.

Yeah try first cleaning the EGR valve and see if the air filter is ok. I cleaned my EGR valve and i saw a big difference in the torque. U can do it ur self it's very easy and simple.
