I replaced the O2 sensors, plugs, wires and then the next week the intake gaskets (upper and lower). Now my mileage is terrible. It runs good, smooth and powerful, but I am only getting about 22 when I was getting close to 30.
I know it is not a bad reading on my average mileage readout, as I only get about 180 miles before I need a fill up.
v6-3800 non Super. about 244k on engine.
What could I have missed or messed up during these procedures?
I am not getting any check engine lights or codes.
:roll:
