History
New engine
I have a 2008 Nissan Altima with a 2.5L and I am only getting 20 mpg on the highway. I have codes U1000 and P0725. I have changed spark plugs, air filter, and ran sea foam. The engine has 120,000 and body has 230,000. I cannot tell if my wiring harness or TCM is bad. Please help!!
