Rough idle from 500 to 1000 rpm then dips down below 500 and stalls out. Doesn't always do it upon start up but will once I hit a red light. While driving I can be fine one minute then the next no matter how hard I press on the gas my truck wont accelerate. Could this be a cat conv problem? Or something else?
