? About some Fault Codes 
My codes are p0418 and p0412 something to do with the electrical circuit for relay "A" of the secondary air injection system and the electrical circuit for switching valve "A" of the secondary air injection system? I am maybe guessing MAF sensor?

Well I replaced relay and erased the code then it ended up popping up again. Then I noticed that there is also a air pump fuse. Checked it, it was burned then I replaced it and deleted the codes again. So far so good, been two days! No more check engine light. Thanx for pointing me in the right direction!
