My Lusso is put away for the winter for the past month. Only has 150 miles on it before winter set in. Went to start it today and it started right up. Let it warm for several minutes then tried to rev it but it would not go over 3200 RPMs. Is in park with parking brake both on and off. Really can't take it out on the road due to icy conditions. What's is going on? I'm pretty sure I was able to rev it over 3k before while in park.
