fuel trim code
Posted this in the W210 forum weeks ago with no joy, so thought I'd try here.
Got a CEL, ran to Autozone, found the code is for fuel trim (two codes, one for left bank and one for right). I retightened the gas cap and have done a bunch of 10-15 mile jaunts (per advice on this site) but still the CEL persists. Is the "fuel trim" message more than what a loose gas cap triggers?
I notice a slight trace of fuel on the cap gasket. Is this normal?
