engine starts fine cold. after warm up still running well shut it down if i start it right away every thing works right. if i leave it off for 10 min or so she starts with #1 cylinder missing.I have replaced #1 coil&boot and all spark plugs.
Could an injector leak on shut down warm? or are there other possible reasons?

Do you get a P0301? I would immediately pull the spark plug and inspect it for wet gasoline. 107K is a bit early for a dirty injector, but depending on the gas station it may have injested some crud. A bottle of good injector cleaner in a 1/2 tank of gasoline might help.

If a cylinder is misfiring because of a leaking injector, it should clear itself after a few minutes at 2000 rpm.

Keeping it running is better than buying new
