Do you know what could be a main reason why my trailblazer wastes a lot of gas??

The problem is that my truck is wasting too much gas it gets like 10 miles per gallon.

Need a couple suggestions as to which spark plugs to use on my blazer for better performance because I want to do a complete tune up on it what else should I do to it. So far the following is done the oil change and air filter.

I got you. Another question I get low MPG. I used to get 17-18 MPG. ..now its more like 8-9 MPG.

The plugs oil change and air filter.

:mad: Most likely because I seen that they did the tune up June of last year. But I'm still worried about my low MPG because it wasn't like that when I got it.

The truck currently has 139350 miles. I used Quakerstate oil 10W-30 with an STP brand oil filter change. I bought the TB in December of 2013 and had it in the garage. Through that time in the garage I started it in the morning everyday for 10 min. I took it out of the garage this past Friday...

I recently did an oil change about 2 weeks ago to my 2002 Trailblazer LTZ. Today the Service engine light came on and I got code p0014. I'm willing to work on my truck to learn how to fix the issue but at the same time I noticed that I get a low MPG. What can I do to fix these issues?
