After installing chinese MAF, i cleaned IAC with wynns spray. Opened air filter box and bingooo! Air filter was dirty and with rubber slightly riped off. Seems to me last owner never change air filter. Second and more important thing, air filter was about 1.5cm shorter than new one I've buyed today. So there was space for air to skip filter. Same look but shorter. So result after changing airfilter, cleaning IAC and changing MAF is: Idling 850 rpms (hot engine)- 1100 rpms (cold) .
