    Hey y'all, so my MPG is shit right now. 15mpg to be exact. I'm thinking of cleaning my mass airflow sensor and throttle body to try to help me save some gas money lol. Anyone ever clean their MAFS and can provide me some insight?

    No reason to clean the AFM. There are no wires inside to get dirty and throw off the readings like modern MAFs.
    I saw a pretty good improvement when I pulled the upper intake manifold and cleaned it out. There was LOTS of buildup inside it and the runners after 270k of use.

    My 22re trucks' intake was fairly caked when I cleaned it after buying my truck at 150k. Enough to make the butterfly sticky enough to feel in the pedal. Throttle body cleaner, rag and a toothbrush was all I used, didn't pull the intake off. I also tried cleaning the AFM and there wasn't really anything to clean like RobertM mentioned. Modern OBDII vehicles have MAF sensors and those you can clean.
