catalytic converter fault codes.

I got 2 codes 29f4 and 29f5

I have a muffler delete and recently done valve cover gasket plugs and 4/6 ignition coils.

I am using my buddies launch pad and these are the only codes I get.

O2 sensor control 1&2 both active and signal, o2 sensor before cat is at 2.01V fluctuating between 1.97 and 2.05V

Vanos position inlet is fluctuating between 84.80-85.26

Vanos position at exhaust -115cr

Vanos adaption, inlet 2.24cr

Eccentric shaft specified angle 35-41 *fluctuating*
Actual anglr 31 degrees

True running value cyl 1 -0.17 ~ 0.40
Cyl 2 0.24~0.42
Cyl 3 0.01-0.04

Went through all those and posted it for you guys maybe you can tell me why it sounds like there is a grinding noise coming from my engine and my car misfires. No check engine light. Going to try changing those 2 coils to 2 newer ones I guess it doesn't matter that brands are different as I've heard.

Thanks guys!
