    Hi everybody. It’s been 2 weeks that I cleaned my throttle body. At first it revs really high but the idle adjust it self eventually. Since I cleaned the TB, the idle bounce from 800rpm to 1300 when I press the clutch in. Eventually the rpm drops to 800 but I dont get why the rpm wont stay at 800 when I press the clutch. Any idea why its not stable at first?

    Thanks!

    Did you unplug your battery when cleaning?
    MAF cleaned as well?

    You may just need to give it time to learn.
    Mine is kinda like that after a battery disconnect, the idle will fluctuate while rolling with the clutch in or in neutral and then settles down when I stop. It learns after a few days of driving and gets better.

    Definitely want to unplug the battery in those types of procedures.

    Mass Airflow Sensor, located in your intake system. Little clip in unit, at least it is for the v6. Be careful with the MAF, clean it only with MAF specified sauce, follow the directions on the bottle.
    I'd say, unplug battery, clean MAF, reassemble and take it for an easy drive, one long enough to get the engine up to operating temp.
