Need idle/maf help

[02GTRX]

My check engine light came on and now my car idles like a hot rod kind of...my tachometer does slighty jump at idle but its not a misfire because it doesnt affect driving performance. I took it to autozone and the obd2 gave me a maf malfunction (forgot what code) but the guy there said it couldnt be cleaned it has to be replaced, is this true? I cleaned out my IAC thinking it was that but that didnt help much. Also when im driving around and are coming to a stop my rpms will stay up at 2k then SLOWLY come down, is this problem related to the maf? According to the scanner both banks are running lean so I really need to get this fixed asap. thanks for any input

Dirty MAF would explain rich/lean and idling problems. It's possible that the IAC is working fine just having to compensate a little too much for the MAF having problems, causing your idle to surge and stay up.

Damn... a lot of reported idle problems lately. I still have a P1506 code I need to solve. I haven't cleaned my IAC yet but it just showed up after taking care of another code and replacing an 02 sensor. My car won't come down below 1200 rpm.

Brand new 90mm MAF so that can't be it (came with my blower kit).

clean the MAF and see if it works.
