Spark plug change time.
Spark plug change? I am new to the group so please bear with the questions. My expedition has 152K on it and is getting 15 MPG. I am getting ready to take it to the west coast from St. Louis this fall and was wondering if I should change the spark plugs? It starts very well and runs great...- Slayor
