Mpg

My 2dr 4x4 with BF GOODRICH Mud Terrain TA 33's was getting about 11mpg? Does that sound right for the tires that are on there? I was driving it like a granny thinking it would help the milage. So then i said screw it and started driving like i normally do and i watched the trip computer and the last mile i drove i got about 15-16 mpg. Does that make any sense?

I know that my TPS is messed up the voltage is a little low. Does that affect the MPG?

Im thinking of selling the tires and getting some 31's so if anyone in the memphis area is interested let me know. They are almost brand new.

When was the last time you did a full tune up??

When was the last time you changed your 02 sensors? They should be changed every 65-75k, thsi is CRITICAL for miledge....

What year is your truck?? If it's a 92-95 you probably have a leaking CPI unit...

Sorry, It is a 1999, I just purchased the vehicle, but someone told me i was getting fair with the tires i have on there. It has 115000mi on it.

I would pull the plenum and check the injectors... Your truck most likely still has the original 02 sensors on it, change them, 115k they're way past due...Do a tune up
