I did a vaccum test on my car to day and is running like complete crap. It came up with 10" of vaccum st idle and 17" of vaccum at 2000 rpms and held there. Also the car is popping and backfiring through the intake. what would cause this to happen? What would cause 10 on the vaccum reading st idle is this normal for this cam?
