I haven't driven the car much lately but I had it out recently and it ran fine. I filled up with premium and parked in the garage. Today it started and idled just fine but seemed to stumble as I gave more than half throttle. I figured an Italian tune up was in order. It revved OK up to 3000 rpm then no power or revs. Last time driven (2 weeks ago), revved to 5000 easily.
