I have a '93 Town & Country AWD 3.3L V6 FI 145K mi. The engine was sprayed w water for about 5 sec while it was not running. After 3 hrs when I started the engine the exhaust gas was a very thick white smoke with a strong gas smell. There were a lot of liquid drops on the exhaust pipe. The fuel guage dropped quickly to about 10 min idling/gal. I made a 3/16 dia hole under the catalytic converter to check if there was water or gas. When I started the engine a lot of liquid was spraying out. It was a beige gas. Trouble code 12-27-55. What part shall I replace? Same probs 5 mo ago.
