Looking for possibilities as to what caused following: Early AM drove about 60 miles everything normal. When slowed going through Lincoln tunnel started to struggle to accelerate. On way back on NJ Turnpike and Garden State Parkway found that it would not rev past about 3000 - 3200 rpm. Had to shift early and topped out at about 65mph but could not maintain that on an incline. Judging by gauge it may have used more gas than usual. My knowledge is limited as I've never had a garage and extensive tools. But hoping for clues before taking it in. Hoping that the astronomical collective Alfa IQ on the board will figure this out.
