Went on a long drive today, car drove find. On my way home there was an accident so I sat in traffic for about 20mins at a incline 0 mph. Traffic cleared up, I started driving I noticed the car lack power to accelerate going up hills, slammed the gas pedal car could barely stay at 60mph. On a level field car still lacked power I noticed the rpms would be in the low 2000s going about 70-80mph. Before this the car was powerful I would accelerate and the car would haul ass up hill and on level ground. Only had the car for about 2 months, has around 75,000 miles.
