i finally got my car running half right, the MAF was shot.now the problem is if im at a dead stand still and mash the gas to the floor it just takes off without spinning a tire. it just gradually picks up speed. i heard you can move the throttle position sensor a little by making the holes bigger and checking it with a volt meter. anyone heard of this ? and if so where is the sensor located and where do i use the volt meter on it.
