00 Dohc 24v Rough Idle When Cold

My 2000 SE 24v has started to idle very rough when the motor is cold. Only on idle, otherwise it seems to run fine. It doesn't idle smooth until it is warmed up completely (Temp needle moves all the way to where it normally is). No codes. Any suggestions?

Could be an EGR problem. The DPFE sensor can go bad and not throw codes . There was a program for extended coverage but I think it is 2yrs/24 k over the 36k B to B so you have too many miles. Could be time for a tuneup if those 76k you have were hard ones.
