I reset my ECU and the problem with hesitation seem to go away now.
I hope it won't come back again since it is so frustrating.

 

I had the bucking problem and took it to the dealer. They futzed with the throttle position sensor and it stopped bucking.

 

I had the problem, and thanks to this forum, a couple of whacks with a screwdriver to the MAP sensor fixed it. This was after my dealer wanted to tear apart my fuel system because they said it was fuel contamination (Metro Honda in Claremont, CA). They still won't admit it was the MAP sensor. Just today it started acting up aagin, three months after I whacked it. It all started at about 10,000 miles. I have a 2000 model. If you need to get any more details, you can email me at Tomcarrjr@cs.com

I would like to have the MAP sensor replaced, but the dealer won't acknowledge that that is the problem.

Let me know if you have any helpful information.

 

Had idle problems, so they replaced MAP sensor, which didn't solve the problem. Then they replaced the Idle Air Control Valve, which also didn't solve the problem. To see what may have solved the problem, check out this thread:

Just for the record, I have an '01 with 27k miles and no MAP problems. However, there is the normal bucking that you would get if you were to a) let clutch out too fast and do weird stuff with the pedals... and b) [WARNING: the following is pure speculation] you know how when you are cruising along at speed, you can feel the LSD's behavior when you switch between acceleration and deceleration? Well it seems that behavior is magnified when you're idling along (in stop and go traffic, for example). The normal bucking you get from the always-sensitive 1st gear of any manual tranny car is magnified by the LSD's behavior as the car oscillates between acceleration and deceleration. Eventually (after a few seconds, given the right conditions) it can turn into a rather violent jerking motion.

My solution (and the reason I probably never see any issues with my car) is judicious use of the clutch to smoothen out my travels over speed bumps, and in slow stop-n-go traffic, not only do I make judicious use of disengaging the clutch, I also ride the clutch, albeit slightly & at very very low rpms.

I don't see this MAP problem that people have experienced at high RPMs.

 

Trust me, my problem has nothing to do with the clutch. The "bucking" I experoienced is like having your engine cut out, and then go. It feels like it's very bad for the car, and when you experience it, you will have no doubt there is something wrong with the car.

 

I too know that all manual transmission cars that I have driven have a "bucking" problem. The one I have is hesitation or bogging. Engine hot, a/c on, stuck in traffic, and take off in first gear. The car bogs and will turn into a bucking action if you don't put the clutch in and rev it a little. So what's the fix for that problem?

 

I have had my MAP sensor replaced by my dealership 2 times.

AY2KS2K, your problem sounds like the one I had with mine when the MAP went bad.

Others: we had a line of 3 S2000's crawling (less than 20 mph) on an interstate (mine, Jims2k, and my brother's), all bucking like mad at times. You guys are suggesting that all THREE cars had the same problem at the same time due to some manufacturing defect? I'd love to think that that could be possible, but I think the law of odds states otherwise. Any succinct explanations why this would have happened to 3 cars simultaneously would be appreciated (no sarcasm intended).
