I am LTWilly, I have a 05 Wrangler X , 4.0L AT. All stock. resently I just got only 9.3 miles per gallon, eventhough I did a tune up with new plug, air filter and the upper O2 sensor. My friend said me I should replace all 4. Any advice will help. THANKSSSS...

Welcome to the Forum
It could be several different things but something to take into consideration is any differences in driving habits, more city driving than usual? Have you been letting it idle to warm up for longer periods? Which plugs did you use for your tune-up? There are a lot of factors that go into determining what the problem may be.
As mentioned above, post your question with a few more details in the TJ section for more views and responses.

Thanks for all replies, I am still new and not a PC guy so it will take me a while to learn how to reply.
I used Autolite as recommended and the gap is 0.035. I just drive to work 8 miles a day and not in traffic time. Today I just replaced all 4 O2 sensors and will monitor for a week.
