I got the block refurbished and with 2 refurbished heads had a professional to install the engine. For eight months the car was running like a dream giving 24 mpg. Two weeks ago the engine started to run rough. The check engine light came on giving a code P0305. Gas fume cam though the air vents. I changed plugs wires but there was not any improvemnts. The check codes did change to P0500. I noticed that on spark plug # 2 was wet. I change the injector but no effect. I change the cam senser and the coil pack but no improvements. With the rough runnimg engine I am lucky to get 10 mpg. Any sugestion.
