Heres some more ideas. ALWAYS BE SAFE and CAUTIOUS
Do your cap and rotor first..

Wait for night time pop the hood and start car. Lightly mist the ignition components and look for archs.

EGR valves can become plugged and give warm or cold only symptoms. On most models using a cold start, you can move the EGR plunger ( located on the bottom side of the EGR bonnet) and note how easy or hard the plunger moves (some resistance should be felt but you should not have to hurt your fingers to move the valve plunger).

With the engine running at idle, moving the plunger should result in the engine stumbeling preaty dramatically nearly to a stall. EGRs can be cleaned when removed if carbon buildup is the issue (Warning cleaning EGR s don't always fix them).

Good luck and remember VACUUM LEAKS can also cause funny idle issues at awkward times. You can use throdle body cleaner and spray the vaccuum lines and listen for idle changes, I like an unlit propane torch for this job, CAUTION MUST BE USED EVERY TIME ALL THE TIME!!!!
