Hey everyone.
Within the past few months, an interesting idle problem started; with 1/3 or less of a tank of gas, the idle sits really low (<700) and will stumble trying to get back up to the normal 700-800. Still happens no matter if any (or no) load is on the engine (a/c, lights, etc.) It idles just fine when I fill up or or if there's plenty of fuel in the tank (load or no load on the engine). I don't think I have an FITV, IACV, or base idle problem as everything is perfect when there's plenty of fuel on board.
Could this be an EVAP or venting problem (if we even have a canister vent setup)?
I'm really stumped.
91EX, 5SPD, all stock.
Thanks!
