runs

I have a 95 jeep wrangler that is have one problem that I can't solve. In the mornings when it's nice and cool out it runs fine. It runs like a new jeep but when it warms up out side later in the day I get a bad hesitation and 2000 to 2500 rpm and no check enginelight comes on. I've replaced...

I am definitely not a repair person and don't know much about it. I have a small leak in the front end of my 94 YJ. Small shock absorber looking device runs horizontal, guessing part of steering? Any advice on what the issue is? Thanks
