2007 Camry 4cyl spark plug change
I have a 2008 Camry 4cyl with 117k on it. Basically I drive anywhere from 80 to 100 miles per day, 5 days a week, for work, and over the past few years the car has racked up the miles. I've noticed a decline in the gas mileage and figured it was time to look into the spark plugs. I'm trying to save a little bit of money on changing them by doing it myself. Anyone have a tutorial on how to do this? I've changed sensors and done a lot of routine maint. on cars, but this is my first attempt at spark plugs. Thanks for the help.
