So ever since a few weeks after I got my S I noticed that when it was cold it would hiccup what seemed like missfire but after it warmed up it would be fine. Well its progressively been getting worse. Only happens when the car is first started up after sitting for a few hours. Under normal accelerations it will hesitate. Sometimes when I shift and get back on the gas it will jerk so freaking hard it looks like I crashed into something. Once the car warms up its fine and I have no CEL. I have no idea what it could be, so I'm going to buy some plugs and see if thats the issue but do you guys think it could be the MAP Sensor?!!?!?

MAP or IAC valve...

If you get plugs make sure you get OEM. Other alternatives are not as good.
