hesitation during acceleration...

I noticed that in the low-end, I get a lot of hesitation when I step on it. For example, when I shift from 1st to 2nd (6-speed) the RPM's are above 2k and the engine tends to bog down for a second when I step on the gas. It recovers, but it's not a smooth acceleration by any means. I'm guessing that the engine is starving for air, but I'm not sure. Are the RPM's are too low? I have 13k miles on the jeep and have only run 87 octane. Maybe I should run a injector cleaner through the engine?

Any help on this would be great.

This is a bit off topic but I see you have the 6sp so you would know this. How long does it take to get used to that electronic throttle pedal? I have been working on buying a new 08 and have test driven multiple 6 speeds and when you shift gears it seems like it takes forever for the RPM to drop. I'm guessing the guys with auto's don't even notice this but with the 6 speed how can you not. Do you ever get used to that? First one I drove it was the first thing I noticed and I hated it but I thought maybe it was out of adjustment till I drove another. Their all like that. I have never driven any vehicle that took so long for the rpm to drop in between gears. It acts like the throttle gets slowly let off by the computer after you lift your foot from the peddle. I found it very annoying.

yea i noiticed that too the first time i revved it up. you dont really notice when driving only if you miss a shift and then have to wait a sec for the rpms to come down before putting it into gear. other than that i really havent had a any problems or noticed it driving any different from my other sticks.

I noticed that too and it drove me crazy for a long time. I just adjusted how I drive it. I tend to take my food off the gas a little early before pushing the clutch and move between gears a little more slowly to allow the RPM's to calm down before releasing the clutch. That's for when I'm taking it easy. If I'm getting on it and shifting hard, it doesn't really matter because you're engaging and releasing the clutch so quickly. Someone told me that the electric throttle is better for off-road, but I don't know if they had a clue!

All-in-all, I just like driving a manual and I find that I adjust my shifting style to the car anyway.

It's a drive by wire system that's geared for fuel economy.
Regearing does help the pep; that's about it.
