These older Hondas are capable of really good MPG! Unfortunately, the Honda DPFI doesn't work with the MPGuino.

I think I had a bad IAC. The idle bounced up and down. New ones are expensive and used ones didn't fix the issue, so I disabled it. Other than sometimes stalling when cold, it's fine without it.
