'secondary air flow system too low' and one cylinder misfire, help

hi guys my car's CEL was on few days ago, the peake tool gave the code11, f2(cylinder#5 misfire), f5, f6('secondary air flow system too low' 1-6) is their any connection between the misfire and low secondary air flow?

well, i checked my secondary air pump on cold start in the morning. the pump seems working normal but when i put my hand in front of the suction pipe, no air was sucked in..... like 1 minute after the air pump was quiet just like normal
any idea? is that mean i have to replace that $300 thing????

appreciate any help!
the car is 97 328is

Air pump

The air pump is only on the first few miutes you start the car then it shuts off. Mine was making some weird noises which meant it was starting to go. I picked up a used one for about $100 and replaced it myself...not all that hard.

Fix your misfire, forget about the secondary air pump.

Check your plugs, ignition coils and ignition boots on the cylinders the computer told you.

i know that the air pump is only work for the first minutes... what i'm talking about is that when it's working the pipe was not sucking air in... it used to be but now not working.... where should i check?

i will fix misfire for sure. but the broken secondary air pump will damage O2 sensor and Catalytic converter and those parts aren't cheap at all....

Really? I don't think so. Secondary air pump I think was put in to have better emissions during the first 1-2 minutes of running. That's what I've heard anyway. That's why Ivan is saying forget about it.
