    Just wanted to drop it here.

    Cleaned MAF sensor using carbon cleaner (named Injection cleaner, spray).

    Attached: Previous air filter.
    I used Leppon's toyota air filter as replacement.

    I found the same thing on my 2007, but I only changed the air filter.

    Strange. I've just changed the air filter and cleaned the MAF in my 2008 and if anything there's a slight drop! :(

    I have a new problem, my acceleration is terrible now, probably not related to this post. The RPM sounds high but car is struggling to gain speed. No DTC found on OBDII. MAF value is 0.6 g/sec on idle (engine off) and 1.9+ on idle (engine on) which goes up to 6 g/sec on 2500 rpm.
