Ideal Idle?
 

What is the ideal idle for the RX8? Mine keeps dropping to around 700-900 after warming up and it starts to shake a little.

I've had the most recent flash upgrade.
Had the carbon blast, and even had a new engine replaced on warranty...
But the problem seems to still persist.
The vehicle has never died on me... but it just shakes at a level that people who are riding with me ask why it's shaking.

Last time I took it to dealer they said that it's "supposed to idle like that" for these rotary engines. I'm not sure as I've always had a Honda/Acura, but I couldn't resist the RX8 body style. :) I'm new to rotary which is why I'm hitting up this forum.

I have an 04, which I've done research on and understand these year models seems to have these issues. However, I'm assuming replacing the engine and having the most recent upgrades would have corrected this.

Does anyone have any documentation or anything showing what the ideal idle should be for this car? I checked my owners manual, mazdausa.com, and the most recent service bulletins thread, and I couldn't find anything with any exact number of estimate from Mazda.

Any help is appreciated fellas... thanks!

That's where they all idle with factory tunes. Of course, if you'd searched for "idle" you'd have learned that already.

Bad motor mounts can make the vibration seem much worse.

Thanks for the responses. I'll have them check the motor mounts.

Also. I did search for "idle"... did not locate anything specific. But then again searching for idle on this forum is like searching for "RX8" :) ... alot of responses to shift through to find what you need.

Also, could this have something to do with maybe the plugs/wires? They mentioned something about that after I replaced the engine but haven't got around to changing them and I didn't know if that would make a difference since they seemed pretty set it was the engine.

Thanks again fellas

The vibration is probably your Engine mounts like Nubo said.

I have the same problem, just bought an 04 and its in the shop getting fixed right now for that and other things. Just make sure you arent paying the $700 they will ask you to pay for this, its covered under your powertrain warranty, unless you are over the 5 years 60k miles?

engine mounts,

depending on mileage you still might be in warranty.

and search for ac amp.. and learn how to program it...

beers :beer:

Hey Guys,

Thanks again for the information. Yeah I'm going to hopefully have the dealer look at again this weekend. I'm under 60k and the 5-year so it should be under warranty.

Also I'll do some research on the ac amp.

Nice, technical, information here on the forums. Glad I found this place!
