Hi guys,

I had my R at my dealer a few days ago to do valve adjustment, change timing belt, oil and fuel filter. My car now idles at 5-600 rpm - about 200 rpms lower than before I recon. I haven't really noticed at what rpm my R normally idles... what should it be?

Do any of you know a reason why my idle can be low? My car is stock except header and exhaust. I am going back to the shop on friday to get this corrected - it is my dealers responsibility, but I just want some input

thanks in advance.

 

you could raise rpm by adjusting throttle with flat screwdriver. if its stock, i don't think theres any other way they have lowered it.

 

Ok, thats what I suspect as well... My mechanic wasn't available on the phone earlier, so I didn't hear what he had to say - but the man at the dealship told me that he probably didn't adjust my idle at the service - but I think he must have.

Thanks - Just wanted to know

 

If they disconnected the battery for some reason, the ECU has to "relearn" the idle. The car has to idle for about 10 minutes or so for this to take place. Or you could be experiencing a case of " my car didn't do this before you guys worked on it". This happens when a customer gets into their car after having work done, and with their super customer heightened spider senses, they notice every little hiccup. In other words, the customer drives around in the vehicle every day oblivious to any quirks the car may have, but after having work done, they suddenly become aware of these same quirks.

Another possibility: the timing belt was installed a tooth off or the valve lash is too tight.

So - just startup the car and leave it at idle for 10 minutes or so, just to check?

Hehe, I know what you mean - but I am positive that my car didn't have this low idle before.

Let's hope not, but anyways - this is something I should notice other than just at idle... or?

 

Ref: mine idles at a steady 840-900rpms

resetting ecu should increase the idle (more like it won't be a smooth and stable but not low), then it goes back to normal after several startups.. at least in my experience with hondas it always has.
