P2100 p0091

I have a 2007 Mazda speed 3 with two codes p2100, p0091 before these codes I was driving and then the car started running like shit then if I floored it it would run good then when I slowed down it started to run like shit again. I have replaced the spark plugs, ignition coils, fuel injectors, 02 sensors, starter, battery, battery terminals I broke down and cleane the HPFP as well as the coolant pump and now all of a sudden these codes and the car clicks but will not turn over the cd player sounds like it’s switching disc like 7-10 times then stops but I am just stuck and don’t know what to do please help
