Does anyone else have an obnoxiously embarrassing smog pump. Today I noticed mine doing an awful lot of ticking and growling at low rpms, including idle.

Can I just simply unplug the connector for the clutch on the smog pump and continue driving as normal without any negative repercussions?

Any advice would be helpful as I know nothing about the smog pump.

In the mean time, do you know if I can simply unplug the wiring harness from the clutch on the pump so that I don't have to listen to it? Will this cause other problems?

Yes, you can unplug the electric clutch wth no ill effects. Your cat will not be getting any air ( if you have one) so you may not want to leave it in that state too long. A few weeks will not hurt your cat. I had to disconnect my electric clutch when a bearing failed in my airpump.
BTW, $40 shipped is a good price, you better jump on it.

How would you like me to pay?
If you are interested, I have a black drivers side door panel for sale. It is in very good shape. Let me know if you would like to trade or something.

Excellent price! Rotary Reliablity & Racing charge me $500 because they wouldn't sell me a $25 Greddy belt when I had the freekin kit allready! WHAT I"M NOT STILL BITTER AFTER TWO YEARS! Yeah, I paid with bendover express! Why, could you look for my lost keys while yer in there?

Yes, you can disconect the elctrical plug and it will spin freely.

Here is the thread that shows the pics of it. The only problem is the plastic connector that broke because of heat cylcing in the engine bay. Still ran fine since their male adapters.

Thanks for the pics. My connector is cracked also, but only where it snaps into the little metal bracket to hold it in place. I wonder if I can manage to push the pins out and use my connector.

Do you know if this is do-able?

Perfectly, you can soder it to make sure it doesnt fall out with bumps and stuff. let me find it tommorow morning when I get the chance (I have it in a box somewhere cause I was about to ship it to a friend)

I have a mid pipe and downpipe so ALL cats are removed. I just installed a whole new exhuast last weekend. While letting the car break in the exhuast and exhuast wrap I did notice the air pump making a moo sound. I have the greedy pulley kit, but i'm not going to install it for alil while since I need block off plates etc. So I can disconnect the airpump some how now and it wont make the annoying MOO noise?

$500 is Greedy. The pully kit is Greddy. You can get block off plates from www.k2rd.com

Having been through this myself on my 96 RS There are a couple of lessons I learnt that might help or even change your mind. My smog pump was making a similar noise "mooing" or "burping" around 3000RPM when I first got it. It was serviced initially by the car yard's garage who disconnected the wiring harness & said it was fixed & not to worry about it. I wasn't overly impressed & on my next service took it to a Mazda dealer/garage. Their most experienced mechanic took one look & said "that's killing your engine" Apparently unplugging it does a couple of things. 1.) Sets the engine management computer into "limp mode" i.e reatrds the engine so you can take it for servicing. 2.) Dumps a S**t-load of extra hot air into your cats (if you're running cats that is) The pump actually pumps cooler air to the exhaust to help combat the high temps that rotary engines produce. Turns out that the noise was the pump disengaging as I accelerated & engaging as I decclerated (It only starts pumping air at arounf 3000RPM) & the reason I could hear it was that my car is running pod filters instead of the standard airbox.

Best fix I know of if your pump isn't actually failing would be to get a Power FC & ditch the pump & the cats all together. Which is what I'm gonna do once I finish paying off an engine re-build (apparently the guy that had it before didn't believe in antifreeze!?!?)

Let me know if I'm wrong (I can only rely on what I'm told by someone who should know... I'm not a mechanic myself)
