Also need to check fuel pressure before start up.

 

Maybe dirty injectors or fuel pressure (pump or regulator or filter) or even bad fuel. I doubt a dirt air filter would do that or ignition since the car isn't 20 years old. But make sure the battery and stuff are checked, thats free.

 

im gonna get some fuel additive to see,...i was "told" that if its the filter and its not THAT dirty might clear it up. but then some guy i talked to today said there was an ignition issue with certain year jeeps. hmmmm
