Over a week ago my CEL came on and I took it to the local garage. The mechanic said it was a bad gas cap so I replaced it with a new Ford gas cap. About 100 miles later the CEL came back on. When you fill the gas tank up the CEL will go out until you get down to about 3/4 of a tank and then it comes on, fill the tank back up and it will go out. Does anyone know what could be causing this? It also does a quick hesitation like it wants to stall when starting out from a full stop. And it sounds a little louder than it used to, almost like an exhaust leak. Other than that, it runs fine, all fluids are full, and the temperature is normal. Just wondering what I may be looking at before I go and take it to a Ford garage.

Thanks for your quick reply!! Is this something that can be cleaned out or will it have to be replaced?

Possibly a slight leak in the evaporative emission control system? CEL code P0442.
Had something similar in a rental Focus that I scanned with my bro's code reader.

actually, after noticing your observation about the leak sound, I would check the purge valve instead. There's a vacuum line that's connected to it, perhaps it has come loose. A disconnected vacuum line would also explain the erratic behavior off idle. The canister itself is basically a filter with charcoal, so there's not much that can fail on it. Both are related to fuel tank venting though, so it could be either.
In any case, it sounds like a problem with a your evaporative emissions control. it's not a critical problem, you can still drive around with it.

As long as the car runs OK, you I wouldn't worry. I drove for about two months like this.

If the tank is not holding pressure (re purge mode) it could be one of the two valves situated ontop of the gas tank....
