    Ok so I Gough the this car and it needed a timing belt tensioner so I put a new one on it and it runs great once it warms up for a min. But if I leave it sit over night and go start it it will idle up to like 1300 rpm then down to around 300 rpm several times trying to stall sometimes it does if I hold my foot on a fast idle for a min it's fine. Any suggestions on what could be causing this?

    You might need an idle release procedure done.
