I'm a new member here and from what I've seen this site looks incredible. Now I'm a computer guy not a car guy. The problem is my wife's 2003 Kia sorento 105,000 miles is sick. It cranks up fine when cool ( hasn't run in awhile) and drives fine. Then after you drive it for awhile say 25 minutes, shut it off and try to start it again you get nothing. Yes it turns over but won't start, after waiting an hour or so It will start back up. Sometimes I've noticed even cold it hesitates when you give it gas like it's going to stall, once you build up some speed it seems to run fine. I've recently had the oil changed ( yes still full of oil) The problems seemed to start right after the oil change, the check engine light is on also. Other than 3, 4, 5, 6 different ideas I'm hoping someone had the exact same problem so either I can ( little help that it is ) help my father in law fix the problem as I'm on a super tight budget and have to get it fixed. The dealership and their surgeon like fee's aren't an option for me.
