MIL/CEL usually comes on and pulls the same code when I am about to run out of petrol.

This started happening after a tune-up at a local Meineke. They basically gave up on finding the leak. I've had to play some games to pass inspection (reset ecu, complete a drive cycle, get it inspected prior to light coming back on).
