My 2003 WRX Wagon (stock, no mods) has 43,000 miles on it and is ready to be turned in off lease. The car had its pre return inspection last week (passed without any problems) and I drove it home and parked it afterwards. Sunday I started it up to move it and the CEL came on (at first solid, then blinking) and the engine was running rough. The car has never had any problems until 2 weeks before I turn it in off lease (and out of warranty). Its going to the dealer tommorow . Any suggestions?
