Well I had my mechanic take a look tht was his first guess but then he listened to it and then he said it could be the fuel filter or pump but he can't tell.

Easy enough, Have him change the fuel filter, and check fuel pump pressure. For a Ford, I don' know what it should be, you can look it up on the web... Bad fuel pump can cause these symptoms....

If the converter is clogged, you won't get much exhaust from the tail pipe.

It ran perfectly before these symptoms occurred and the CEL wasn't on for the longest time and it would do this until yesterday when I was going up a small hill
