how to chang spark plugs on 04 taurus (vulcan)
Hi, I have a 04 taurus with 71,000miles on its vulcan V6 3.0. I only get about 17 city MPG (I drove about 2 miles to work everyday.) and my idle is boucing back and forth around 810-860rpm(not all the time, but one in a while).
So I'm thinking about changing the spark plugs, is this could be the reason for my problem? It said the spark plugs need to be changed at 100,000miles on the manual.
The other thing is how could I access to the 3 spark plugs in the back, do I need to take off the intake manifold to work on the spark plugs? thx very much
