code keeps saying 23 I think, which is O2 sensor which I replaced a few months ago. Did a tune up about a year ago when I bought it. I think it's a 3.1 V6. Don't know what TBI/PFI is.

23 is for MAT voltage high if ECM sees temp low will think engine is cold and richen fuel mix. Will need OHM meter check OHMs across terminals of temp sender, top engine left below coolant outlet and MAT ,on air intake ,ie. cleaner. wneh cold both will read HIGH resistence as air and engine warm both will fal in resistence. if one or both stay HIGH replace

Manifold air temp,
Engine control module or main computer,
OHM is a measurement of electrical resistance, used in testing electrical senders and other electrical equipment, an OHM meter fitted to a multi meter is a hand tool used to do these tests.

If this is all a tad strange and you are unsure, best let a mechanic check these for you.
