Alright this has been happening when I'm coming to a stop while in gear with the clutch in. As I'm approaching the stop or even just coasting around a parking lot with the clutch in or entering the garage, my rpms drop REAL low and then pop back up then drop real low again. It won't happen when I'm at a dead stop or in neutral. Any ideas as to what's going on?
