My brother has a 1995 Contour GL, 2.0 Zetec, ATX. A few months ago he pressure washed under the hood and accidentally (not knowing) got water down around the spark plugs. So, when he started the engine one of the plugs cracked and that's when he found the water. He replaced all of the plugs with autolite's I think. The problem is that after that incident he has only been getting 23-24 MPG. He used to get 27-30 MPG. Does anyone know what could be wrong? His car has 85,000 miles on it. Thanks for any help!
