Increased emissions

as a result of increased emissions in my case it was the secondary air valve and pump failure,SES ON , and system running lean according to OBDII codes, so i did some research and found out how to check the secondary air system ,turns out by visual inspection i found the hose that comes from the pump to the valve was pinched right before the valve, not a durable hose kinda thin for being that close to the motor ,i order the hose and valve (pump was good) from about thirty dollars online ,for the time being i installed a stent in the hose to keep it from collapsing and stopping air from passing though,i reset the SEL light fault codes and its been good no SES of for like a week ,untill i ran into some more issues with another increased emissions fault with a engine malfunction reduced power error message on idrive system,so what now i said to myself ,ran a code search on OBII turns out im running lean again and random miss-fire misfire on cylinders 1,2,4 bank 1 bank 2 on o2 sensors ,rough idle like crazy the tack was bouncing and it was making a weird noise from the intake ,flapping rattle sound ,checked out online and found out it was my disa valve (air intake mixture valve) have it on order now ,soon as its replaced i am going to reset the codes and see whats next ,
