Need some help I have a 07 cx7 awd just recently replaced the pcv and the hose because it was completely split open while in there I also replaced the oil separator gasket and cleaned the gunk out of it and the egr metal tube and cleaned the throttle body as well got it back together and it didn't want to stay on kept turning off and if I pressed the pedal that made it turn off quicker it then set a p0193 fuel rail pressure sensor circuit high and now it will run but wont go over 4k rpm and the power its reduced I've already tried replacing the sensor on the fuel rail thats by the power steering pump but its still is doing the same thing. Any suggestions I'm stumped
