poi-boi,
Did you ever get your hesitation problem figured out? I'm on my 3rd tank of PD Blaster fuel cleaner. I did change my alternator because I had an open diode, it did help. This is the first alternator I ever changed in a Honda & quite a few had over 200,000 miles on the clock.
So I still could have a bad TPS on an O2 sensor right. I do not have a CEL. Again, I have no hesitation or stumble in 1st or 2nd gear at any temp. In a diesel they would call it dead pedal.
Thanks,
Dave
