It started about three months ago. When the tank got below 1/4 tank it would stall. I could get it restarted but I had to keep the RPM up to 2000. I would have to keep the rpm up or it would stall if i had to stop or go around a corner. It was fine as long as i kept it over a 1/4 tank and then it started doing it at 1/2 a tank. I also notice it did it if i parked at a slight forward downward decline. I changed the fuel filter and it did not fix the problem. It recently did it at a full tank (so I’m at the top of the barrel with nowhere to go). I believe it is bad on gas mileage but that could be because it is a ford explorer. I know it’s not bad gas because because I put premium and also full system cleaner trying to clean the injectors. I did get a batch of bad gas once, but it went 4 months without a problem after that. In the summer it was making this loud howling sound, when i applied the gas the howling quit. I have not heard the sound since fall, I changed the air filter it still did it. It just went away though, I do not know if these problems are connected in any way.

The howling and the lack of idle is most likely due to the Idle Air Control Valve malfunctioning.The fuel level may be a fuel pump going out or an issue with the fuel tank unit itself having a problem that requires it be submerged to work
