Jeep is running better, but its still blowing black smoke and it strains and stutters when I hit 45mph.

I'm going to check the 02 sensors next. Any tips on checking them proper?

Now I'm getting error code P0118 and the lean fuel code. Ugh.

Put in both 02 sensors and the jeep is running like a champ. Wont know if my mpg is better until I drive it some more.

Thanks for the help everybody!
