04 Spark plug change
Just changed the plugs this past weekend and what a difference. I was getting for mpg 12.5-13.5 combined. Now I am getting around 15mpg, according to lie-o-meter. The job took around 2.5 hours and was not that bad. Although my right knee is sore from laying on the radiator. I replaced spring and boots along with plugs. All plugs looked good and most were around 59 thousandths in gap with exception of no. 1 cylinder that was about 63 thousandths. I did use anti seize and torqued plugs to 20 ft-lbs. engine was cold. I will go back in a few thousand miles and re-torque just to make sure there are no blowouts. The truck is smoother and sounds better too.
Now I have to change plugs in wifes Murano.That will be a PITA. Have to remove the intake to reach the back three plugs.
If the people that designed these things had to work on them, they might change the design, you think!?

I had an '93 Honda Civic where the oil filter was underneath the intake manifold so you need to put it up on a lift to see it. Using ramps on the front wheels and getting under from the front still did not allow you to see it. You just had to feel for it.
