rough idle at cold start up.

[deskjockey]

Temps have dropped down to the 30s-40s in the mornings and evenings. When I first start up my 96xj when it's cold it will idle a little rough until it warms up, or I drive it around a bit. Got any thoughts? Both O2 sensors have been replaced less than 8,000 miles ago.

Possibly the IAC relay/harness at front of valve cover. Make sure it's clean. For problems like this, check the quick disconnect harnesses that are near sensors. Clean them up with electrical cleaner.
Also, try SeaFoam. . . it really does help rough idles.
