Mileage drop

210,000 miles, mileage dropped to 14-15 mpg. Changed plugs, air filter. Not throwing any codes. Today I changed the two upstream 02 sensors. We'll see what happens.

No codes, did some basic OBDC scanning, nothing obvious. Valves adjusted a couple thousand miles ago along with new plugs and air filter. Brakes dragging eh? Cleaned and lubed the front caliper pins last year (they were kinda seized). Today checked the hubs with a thermoreader and the right side is running hot. Pulled the wheel and caliper, pins were good but pads were jamming up on the carrier and had uneven wear. (Sigh) so over to RockAuto for Z36 rotors and pads. I'll put those in on the weekend.
