Would spraying a lil wd 40 be wrong, or maybe some carb cleaner or fuel
injector cleaner?  It sounds like its stuck or something is blocking it from
moving freely.  Can you take the throttle body apart and inspect the TPS and
maybe get it to move freely again?  It may take some time, but I am sure it
won't take you 550.00 worth of time.

Good Luck.

OK, I know this doesn't answer your question but it has some good tips.
It's a copy of an earlier post about another Honda problem:

"there is a Honda technical service bulletin number 98-042 that states
that the repair takes around 2.5 hours.

the following site is a site for Honda techs:

www.tech2tech.net

go into "The Library"
click on "accord"
scroll down to "94-97 2.2 engine with crack in the block at exhaust
manifold boss"

or the direct link:

So this doesn't solve your problem but use those links and search for
your problem.

Hope this helps.

Hi Mike,  I may have given some out-of-date advice last time but let me
try again.

Go to:

http://cgi.ebay.com/ebaymotors/Honda-Acura-TPS-Throttle-Position-Sensor-Civic-In
tegra_W0QQcmdZViewItemQQcategoryZ6763QQitemZ8009778873QQrdZ1

Not sure if this will show up as a link or you may have to copy and
paste it into your browser.  It says, "You are bidding on a used
Throttle Position Sensor with the Green Gasket and Mounting Screws.
This piece was pulled from a working 1996 Honda Civic.  This sensor
will work on all Honda and Acura cars with B series and D series
throttle bodies between the years of 1988 to 2000.    Always check to
make sure before bidding.
FOR JDM ENGINE SWAPS:  Many TPS Sensors are broken due to poor
shipping.  This unit is perfect to replace your broken TPS Sensor
The TPS sensor is not available as aftermarket and can only be
purchased through honda by purchasing a brand new throttle body.  Here
is your chance to save big, so don't miss out."

It sounds like what you're looking for.  Better check to make sure.

To find it, I did a search on eBay for "Honda throttle position
sensor".  The link above was not the only hit.  There were some more.
Try doing your own search.

Also, since it IS eBay, check the feedback of the seller.

Hope this helps.

Andy
