Hello. Lately my radio has been buzzy when engine is on. I don't have this problem when I use my CD player. Could it be caused by bad radio noise condensor?

Sure it isn't your speakers? I recently had a audio/video system installed in mine because the amps went south and I didn't like the sound of the stock system anyway. I retained use of the stock head unit because I don't like the looks of the aftermarket kits, change the ergonomics of the console too much. The shop that did the work told me they have done over 50 NSX's before and have only seen 1 head unit bad. Food for thought anyway.

Yeah, I"m pretty sure since the noise goes away when I stop the engine....it's picking up noise somewhere, but I don't think it's grounding noise since I don't have any noise when using CD player. hmmm
Just curious, have you done anything with the spark plugs lately?
is it on AM, FM or both?

I believe it's both AM/FM. I did change out my plugs to Denso Iridium about half a year ago.
I had the same problem when I changed to Iridiums.
Take out a plug and look at the top cap. The top insulator screws onto the stud and leaves a threaded hole at the top.
Now look at an OEM plug. It has a solid top, not a screw in nipple.
The center conductors from the coil packs are real narrow and actually go INTO THE HOLE in the top of the Iridium plug and make poor contact which create spark gaps that make the radio noise.
You might take a screw of the same thread, screw it tight into the top of the plug and cut off the excess threads with a Dremel and sand it flush to make it like the EOM plugs.
This actually worked for me and has been great for over a year.

Interesting. I'll have to check this out. Thanks a bunch. How did you figure this out though???

What year is your car?
There is a TSB on 95's and some 96's that describe your symtoms. I had a related problem and they replace my coils and plugs. Check the TSB's in FAQ. I have a copy of the TSB in files if you determine this might be the problem.

you have a good point Rich. My car is 94 but the TSB you mentioned looks related. Basically, poor contact of the coil and the plug causes the arcing which causes noise. I knew I should have gone with OEM!
Thanks for the help guys.
There is almost NOTHING these guys don't know about these cars.
They are AWESOME.

I did this and no buzzing no more! Man, don't buy Iridium plugs, guys!
Glad it worked!
This drove me nuts until I finally figured it out! After the second set of plugs did the same thing and the Acura plugs not, I just HAD to figure out why this was.

I really appreciate your help. BTW, i sent an email to Denso about this problem and of course, they did not reply...
