Engine Performance problem
2003 Chevy Tahoe V8 All Wheel Drive Automatic 87000 miles
I want to know how to change the spark plugs in my 2003 chevy tahoe. Does it take a special tool to remove the spark plug wire from the spark plug? Please tell me how to do it. Are there better spark plugs to put in than original equipment? I am looking for a good quality plug with the least fuel consumption.
