my AP1 makes a vibrating noise when decelerating from high or mid RPMS. Does anyone know what causes this or what I can do to fix it?

 

Is it sound like it is coming from behind the seats???

 

Look up threads on clutch buzz. You can either get a new clutch, or live with it. It is not bad, just annoying.

 

im not sure it only happens when you let off the gas between 4,000 and maybe 7,000 RPMS. It seems worse when the A/C is on.

 

actually, i have this same problem. except mine is from 5k+

i tried posting for a response before but no one replied
i only noticed mine happening after i did my 60k maintenance so i have no idea what it is.

for some responses!

 

sounds like the rear glass but isnt ? and its behind u mine came from the trunk at one point (jus one of the causes cant find the other) at some point the tension rods? whatever u want to call it for the trunk one shifted a bit and start pressing against the other with the trunk closed i tap on the rear of the car the plasitc jus infront of the trunk lid and it rattles. i readjust the rods periodically but they shift again once in a while

 

The plastic tray the rag top lays in will rattle and buzz sometime. Mine did after I installed a new exhaust.

 

Prolly the clutch buzz. It's TSB-0054. TSB link from the FAQ page.

Here's the complete FAQ page, which is your friend.

When I had the TSB performed at my Honda dealer, I explained to my service writer that I was grateful that Honda was going to perform this, but that I really didn't want the buzz back in a few months, which happens to a lot of guys. So, the performed the clutch job with some of their parts, and some of mine.

They installed the *updated* Honda disc, throw out bearing, and pilot bearing. I supplied a Comptech lightened flywheel and an ACT pressure plate. They installed all of it. No problems with the cluth since. Buzz has been gone for almost 2 years. No worries.

You probably can't get the Comptech flywheel anymore, but you can get an ACT flywheel which is a nice piece. You can get the parts here.

Do a search for "tsb 0054" and you should find plenty of threads that will describe the problem. At about 35 mph in 3rd gear under decel, that sucker outta buzz enough to make you wanna drive the car in a focking ditch.
