cold start hesitation & rough idle 560sel

91 560SEL - cold start takes awhile to fire up, once running into the store 2 mins later - fires up immediately .. e.g when warm, car starts right up with no hesitation . . when cold, takes about 10 secs before it starts - battery is AOK.

I also have another issue which may, may not be related. The car has now starting idling ROUGH when in park. It runs like a beast when I have it on the go but it's starting cold slow and idling ROUGH when at a traffic stop.

I am new here so look forward to whatever insight and guidance you can provide . . thanks
