Go back to ac delco iridium plugs. Did the SES light come on after you changed the plugs?

It's a truck, saw off the cab top and weld on a lower lid, cover the bed and buy smaller rims with lighter tires. Get the picture your bought a gas hog, live with it. If you do buy something to improve your mileage it will cost you more than you can save. That's life!

hm.... i guess i am on the quest for couple more miles. I really believe that abo 18 mpg should be normal gas consumption.

You can unhook your battery and make the light go off,but as someone said,if you dont fix the problem its on for,your wasting your time.Good Luck!
