The emission light on my 2005 espedition came on and it started to idle rough. When put in park it will only rev to just under 3000 rpms then cut in and out. Yesterday I just got back from a 400 mile trip and it ran great. Also the Ac seems to cut in and out. I just got the AC compressor replaced 2 weeks ago. Could it just be a bed tank of gas?

I would start by having the computer scanned for trouble codes. If the light is on, there should be a code stored. Most parts stores will do it for free.

Let me know what you find.
