I searched for rough idle and didnt find what i am looking for.

When idleing for a while, ususaly with AC on, the car will randomly start a choppy idle/ camming really bad, then correct itself a minute later. Is this normal? For that minute it sounds like my old gto with a cam in it

 

Normal, no. Common, yes

Sadly a lot of mini owners report stumbling idle, but only for a few seconds.... so someone else will have to chime in and tell ya if you are having the same problem as what I'm talking about, a minute seems a little long..

And yes, when I attend autocross/events and I leave my car on while I'm talking, it sounds like an old muscle car for a few seconds

 

My '03 did this once in a while, I just gave it a quick rev, that always seemed to clear it up...

I'm thinking a dirty injector might be the cause of this - it only takes one.

 

I know its not the injectors, well on mine. Mine did it before and after i changed out my injectors to brand new JCW injectors.. i read somewhere it is some sort of ECU related problem, if i remember correctly once the cars were reflashed to the newer ECU, in '04?, this happened, i know a couple people have verified this by switching back to the old program. Makes me think now.... Anyone had this problem and it got fixed once you got a tune Well if no one posts ill tell you in a month when i get a RMW tune

 

Initially this was described as a 'yo-yo' idle for which there was a software fix. In my 2004, the fix significantly reduced the frequency and severity of the yo-yo, but did not eliminate its occurrence completely. I've learned to live with it; mine never completely dies, and as another poster has remarked, a quick blip of the throttle makes it go away.

 

Don't forget to pick your time slot...


Regarding the stumble, I don't seem to have experienced that. It may be the computer just recalculating something. Maybe a sensor is getting old. You just have to wait until it gets bad enough to tell you which one if that's the case.

 

honestly, when i give it a rev it stops and idles correctly. also it never dies, just "cams" for a while and then goes away. Im not worried until it starts dying. Thanks guys, hopefully someone will figure this out

 

if it never dies, and once u tap the gas it straightens back, i am gonna bet my marbles that you have what a lot of us experience everyday at stoplights...
