I had the previous TSB done that mentioned the popping noise from intake done a several weeks ago and I still have the issue occurring. Pretty embarassing slowing down to turn and when I accelerate it jerks the car and has a loud pop noise then starts accelerating. Had one guy jump while standing at a corner when I was turning and it did that. lol. I'll have to bring it in again to have them do this TSB and hopefully it fixes this concern.

I've been having intermittent rough idle when the car is warm - prior to today all I could feel were vibrations through the car but I saw the tach bouncing around slightly this morning.

Could this be related?
