Ok, first off, right section
Second, what octane of fuel are you running and how many miles on the KK?

Not sure if this is the right section for this post. Anyways, does anyone ever experience a slight and I mean a very slight hesitation sometimes when driving down the road? Or a slight hesitation at idle sometimes? I do. The dealer said the computer had to be flashed, so the overdrive kicked in at a higher speed. It still does it and I was just wondering if anyone else experienced this before. |

Usually in overdrive speed mostly at @ 45 mph. sometimes i'll be at a red light and the jeep almost shuts off but comes back on (rarely but happens enough to notice 3x's a week) |

i does happen to me while on the cruise control sometimes. I usually dont mind but once this winter it did it like the engine shut off for one second and a light came on on the dash. took it to the dealer , they replaced some cables on the throttle. I still have the slight hesitation sometimes but never as bad as that time |

Have you had all the TSB's done? If so, then you will need to take it to the dealer they can recalibrate the throttle response. They key trick doesn't work any more, according to my service guy. |

I am kind of baffled  i did the key thing this morning, i drove to work (18 miles) no hesitation.
and 18 miles back no hesitation. i am going to give it a couple of days and see what happens b4 i go back to the dealership.
