code problems 4 in 1 day any help

Knock sensor, imcc , varable tumbler control, and cmp sensor. What could cause all of this at once?

Are you sure all 4 codes happened at once or are some of them stored codes? The VTCS solenoid is probably bad, the cam sensors don't fail very often but can go bad and knock sensors commonly leak but don't throw a CEL.

The cel came on and was throwing code for cmp sensor. Then the light went off by itself and then about 20 miles later it came back on so stopped at autozone to get it checked and then the imcc varible tumbler control and knock sensor came up.
Just wonderinh what could cause all at once. Its a 2003.5 speed and it only has 95k miles.

The begining of my experience the #1 misfire when I bought the car it sputtering and iy juat need a tune up which was fine with me. Then 126 miles later the light came back on and for egr valve. It was just unpluged for some odd reason. Then reset the code and 73 miles later had cmp sensor then went off then 20 miles later came back on and it is the imcc variable tumbler control and knock sensor. The light went back iff at 10pm tonight and hasn't came back on yet.
Juat wondering if anyone else has ran into the same problem? I've only had the car for 3 weeks and I'm new to the mazdas. So any help is very appreciated.
