Hi,
Does anyone know if cleaning the Throttle Body in Civic 2000 will improve
the performance. If so does anyone know where it is and how to clean it. Is
it easy and what cleaner/kit is required. Pictures will be really helpfull
if someone has a link somewhere. OR is it better getting it done at the
dealership.

Really appreciate it.

Thanks
NL
 
I removed and cleaned the throttle body of my '94 Civic earlier this
year, and found that the amount of gunk and buildup was close to
nothing. I do not think you would see any performance increase by
cleaning yours.

If you want to have a go at it, the TB is mounted to the end of the
intake manifold. The plastic air duct from the air cleaner ends at the
TB. You will also see that the cable from the gas pedal terminates at
the TB. If you start taking things apart, you really should get yourself
a shop manual from http://www.helmic.com unless you already have one.
Keep in mind that the throttle valve end stop is factory adjusted and
should not be touched by mere mortals.

You can also buy an after-market throttle body with a larger diameter
bore. You can find them many places, including http://tinyurl.com/pd9e.
I do not know how well they work.
 
Cleaning the throttle body will not change the performance of your
Civic. If you feel a catch in the throttle when you first start the
car then it might need cleaning. I've never seen a 2000 Civic that
needed it. If you should decide to clean it you need to remove the
throttle body from the manifold and the cleaner in the bore. Honda
has a throttle body cleaner that will remove any carbon buildup that
you might have... Again if the throttle is not sticking closed then
you don't need it

I agree with the other intelligent posters that told you that's it's
usually a waste of time. I advise you to go an auto parts store and ask
the salesperson for the best gasoline additive that is designed to clean
the nozzles. It should also clean out all of the lines and related parts.
Also, check your air filter--it may need to be changed.
 
Carbon build up on the inside of the intake manifold and on the idle air
control valve do affect idle and performance. I recently cleaned my intake
manifold with seafoam from Napa and took the IACV off the intake manifold
and cleaned the screen on it well. This smoothed out my idle and my car
runs much smoother. By the way I have a 94 Acura Integra GS-R. If you have
an idle problem such as hunting for an idle, surging, rough idle, or high
idle when warm then the first step I would take is do what I did above
otherwise cleaning the throttle body is not going to do much for you. After
you are done, reset the ECU and your car will be like new again. Also it's
not going to hurt the car if you give it a little cleaning ; )
