I'd say check ur sensors starting with ur o2 sensor! I've ran into that once before! Goodluck

also check plugs and wires. sometimes these go bad over time and, due to the firing not being at proper intervals, some of the gas won't fire. it is then discharged and wasted. replacing them will clean up the timing and firing and increase fuel efficiency. hope this helps
