i had 2 costomer cars come in with the exact same problem. one of the cars i swapped coil packs plugs and map with mine. it didnt change, the check engine showed misfire codes in all 4 cylinders. it turns out the valves were out of adjustment. one of the adjusters were actually loose. the second car naturally we just adjusted the valves right off the bat and the idle was smooth as butter.

I have this EXACT same problem!! I dont wanna hit the MAP too hard and crack it or anything ha. But this problem is really annoying especially when you are in traffic and afraid the car may shut off.

Took mine to the dealer today and they couldn't think of anything it could be except blaming it on my K&N intake. They said if it was the MAP sensor the CEL should be on though.
