Purchased car Jan 2012 first winter: Ran fine (so it seemed) but needed to be in S Mode all the time as the E Mode seem to take a bit more peddle effort to motivate the car but ran smooth in either Mode.

2012 Winter: Colder than "Jan. first winter" so car ran sluggish/rough till warmed but seemed to idle ok. Changed plugs and helped but running a 10W-30 instead of the 15W-40 made it improved considerably but not perfectly and still in S Mode.

2013 Winter: Found Altitude Barometric Pressure Sensor was not working when INDY reset the SRS. Cleaned contacts and car ran fine in E Mode for awhile anyways till it got real cold so back to S Mode. Found timing was off when changing the water pump and set to specs. Car never ran better even in a 2 week of mid 20's degree weather. That's consider cold for N-Cal. Starts up strong and drives off smooth (2 Months).
