Kyle, if the rough idle thing goes away after a short time (minute or so) I
would check the O2 sensor. I know you replaced it, but this has happened to
me. I replaced mine, and I don't know if they gave me a wrong part number
(there were two listed) or if I just got a bad one, but mine would idle REAL
rough the first minute of a warm start. The best way to describe it was
like it had a MONSTER cam in it, then it would clear up magicaly all of a
sudden. I replaced all kinds of stuff, finally in a fit of desperation I
put the old O2 back in..... fixed it, hasn't acted up since (about 8 months
now) But it's getting time to replace the aging sensor....
