warm start stumble
i just aquired a 99 grand cherokee limited edition 4.0 4x4. at times on a warm start up it sputters real bad but when i start to drive it and it goes away and runs fine. any ideas? no check engine light and no codes.

I have a similar problem with my '97 ZJ I know I need to change my crank position sensor because it takes forever to start, I'm assuming this issue could be linked to the same sensor being bad

Mine did the same thing, crank sensor was getting heat soaked. When you start to get some air flowing again it cools down, runs fine.
