For a few weeks now my check engine light has come on for a few days, then off for a few days only to come back on for a few days - it's a repetitive cycle. Last week I figured out the pattern. If I have a full tank of gas, the light is off. It stays off till around 220-240 miles with about 1/4 tank showing on the gauge. Then it comes on. It will stay on until I fill the tank. Doesn't matter if I fill it right away or wait until the fuel light comes on. After filling the tank, it goes always turns off within 20-50 miles and stays off until I hit around the 1/4 tank level again.
I'm setting up a time to take my car in to have the codes checked, etc. But unitl then - anyone know what could be the cause of this? I'm guessing poor fuel delivery when my tank falls below a certain level (around 1/4), maybe causing a lean burn? faulty fuel pump could be the culprit? I had both the up and down stream O2 sensors replaced a couple months back when it was doing the same thing. Looking for thoughts. Thanks.
