Good thought. I will try that.

Thanks,

Those are conditions of maximum EGR use.
I'd check there first.

I have noticed this on several cars - slight hesitation at part throttle
- mostly when one eases on the accelerator very slightly. I suspect
there's a way to stop this by messing with the fuel mapping but it might
be what's seen as an acceptable penalty for higher MPG figures. And
that's as good a rational as any, for me, at least. :-)

All,

I have solved the problem I posted, and I am a little ashamed at the same
time. This past weekend I went to start my car and nothing happened, then
tried it again and it started. I checked the battery and found the positive
post to be excessively corroded under the red plastic cover. I took the
connector off and cleaned it well including the battery post. The car
starts and runs perfect now, NO MORE HESITATION! The lack of battery juice
must have been causing the bucking and hesitation.

Thanks to all for your suggestions.

Thanks for your post...you've described the condition exactly. Never really
thought about pursuing the issue because I knew the Techs would say "cannot
verfity concern" and send me on my way. Honda-Man says it was his battery
terminal, I'm happy if he is, but I don't see how that relates once the car
is running. Oh well, we all learned something.
