This was for Clint Gowthrop of Seattle, Washington
This particular Honda, being my first, took about 1 1/2hrs. Ron's video on the Honda air filter box was a big help.

Unfortunately, Clint was limited on time but I could see that the ecu was still adjusting.
On the plus side, Clint had been watching the video's and had talked with Ron so he is familiar with the routine, especially with the Honda's.
Clint will be sending an e-mail as he gets results on the Honda's performance.
This Throttlebody has the coolant lines but there is very little coolant loss when they are disconnected.
Other than the air filter assembly removal/install, the second most difficult part is getting the air intake connecting hose off the TB. The hose clamp TB side clamping screw actually blocked access to the lower left TB mounting bolt.
Overall, removing and re-installing the plenum assembly was most of the work, getting the TB off, grooved and back on (2 connectors with release tabs) was a cakewalk.
