I'm agreeing, heatsoak isnt really a cause for a problem like this. Its just simply injection nature, although some will say fault.

Well after about 3 days my car has not done it again, but it is also been in the 70's. But when it was doing it I was slipping my clutch like crazy and that was the only thing that worked for me......
Thank you Xviper and everyone else that chimed in!!!!!
Well got to go to sleep.....Got a 16 hour drive back to NJ
BTW that car show in Daytona It took 4 1/2 hrs just to get there from Orlando b/c of all the traffic. And there were about 40 cars. But there were 3 S's in the show. I think there were more cars on the beach!!!!!
Thanks again
Kenny

OK here we go again..........Just got homew last night and my car started to do that bogging again.....so I cant blame it on the heat b/c it was cold here. I found out that the car did it at 1700 RPM in second gear going about 11 MPH and I was able to hold it there when it was doing it. Once i pushed the gas a very little bit it stopped. But no check engin light. It seems to be something with the fuel. it sounded like it was only running on 3 cylinders for a cupple of seconds. I pulled my plugs and they looked fine, but one of them, the 3rd one back from the front of the car had a little oil on it. Nothing to be scare of. Could it be a dirty injector of something?????? I need to figure out what it is. I have had the car for a year now and this has never happend b-4 so i know it is deff not just the car acting up b/c of the heat. And Honda dont know shit about the S. Any help will be apreachited thanks.
Kenny

Kenny, I'm going out on a limb here and tell you there is nothing wrong with your car. You are going 11 mph @ 1700 rpm. You are "lugging" or almost lugging the engine. Whether you knew it or not, your throttle position was such, that you were still trying to move the car forward (slight acceleration).
Here's the scenario:
At that given road speed, in that gear, in that particular road condition (slope or type of road, etc), you are lugging (or nearly) the engine. The engine, at those rpms, does NOT have much torque. You are asking it to propel a certain weight of vehicle down the road. You are asking the motor to spin faster. The conditions at hand will NOT allow that to happen. Your throttle position is such that you are letting in too much air. The ECU tries to give it more gas but the motor can't handle that much gas because it cannot speed up very well, so it repeated nearly dies (or gets to near flood condition). Your motor cannot decide whether to go to idle or to go faster. It can't do either, so it bounces back and forth.
You now know what can initial this bucking. You have a slight clue as to how to stop it. You also now know what it will "begin" to feel like. There is a "cure" or a solution to this. Try to avoid extremely low rpm, low road speed, too much throttle position (and during these times, it doesn't take much throttle to do it). Use more throttle when taking off. Slip the clutch a little longer till you gain some road speed. Don't shift into the next gear at such a low road speed. HOWEVER, if you find your self doing it again, since you know how it starts and feels, you can tell very early it's about to happen, SO, push in the clutch immediately and start again but this time, slip the clutch while giving more throttle before and at the clutch friction point OR, if you are in second, go back to first.
So, you say, "But no other car does this". I'm telling you that other cars do this. It's just much easier to do in this car due to it's specific characteristics - those being, a car that has an extremely high redline, relatively small displacement, multi-valves, relatively high vehicle weight, specific tranny and diff gearing, relatively small and light flywheel.
I don't like to tell people they don't know how to drive so just let me say that people simply need to learn to drive THIS car a certain way to circumvent some of its quirks due to its inherent nature as I have described.
Honda could have minimized or even prevented this issue by putting in a 2.5 liter engine or a V-6, put in a larger, heavier flywheel, changed the gearing but then, we wouldn't have an S2000 as we know it, would we?
