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. At 15 miles to the gallon it seems to be running fine. I just want it to be ready.
Also if there is any additional items to check please let me know.
