I solved those symptoms with a MAF sensor replacement. The CEL was P0172 (system too rich).
I had similar trouble later but this time CEL was P0304 (cylinder misfire) with additional symptom of engine shaking, not just rough idle. That was fixed with replacing the valve springs.
Get an OBDII reader and post the CEL number here so that you can get better help.
BTW, normal warm idle is ~800 rpm. If AC or radiator fans are on, idle goes closer to 1000 rpm.
