Cooper S Rough Idle Possible Fix!

We took Molly up to Motorwerks MINI to have her CD player replaced under warranty. In addition, I wanted them to check out the "rough idle" condition we noticed a day or so before. This happened when we were parked at a gas station and just sitting there. It started to stumble between 500 and 700 rpm. I blipped the throttle and it stopped. Hadn't had an issue since.

So....

Jim the lead service tech. (and in our opinion probably the best and nicest MINI tech in the Midwest...possibly the world) started checking her out. We headed off the mall assuming we would have Molly back in an hour or two. We were a bit mistaken. They called us after 2 hours and had the shuttle pick us up from the mall. When we got back, they had a courtesy car waiting and took us back to Jim so he could explain what was up. When he ran a diagnostic test, he noticed that the overall fuel correction percentage (this isn't the correct term but I forget what is) was 7.6%. Another Cooper S he had tested earlier in the day was running 1.6%. Essentially this indicates that the engine is running in a lean condition and the computer is compesating by adding extra fuel. Anything under 10% will not throw a CEL, and over 10% will. But...he thought it was still too high. So he started to look for vacuum leaks. He found one in the intake tract between the throttle body and the supercharger. He wasn't sure if it was the gasket or the intake pipe itself so he wants to replace both. Unfortunately the parts won't be in til tomorrow so we went home MINI-less. However, he said this should take care of the rough idle issue.

Those of you experiencing the rough idle should have this looked at! I don't think this particular part of the intake tract was changed between pre-'05 and 2005. It's a relatively easy fix.

Anyway, so we're headed back on Saturday to pick Molly up. Good as new!

Oh, and Jim....if you're reading this...you rock!!!! You are the nicest, most helpful, and most knowledgable service tech we have ever met. Thanks for all the help!

Thanks for that! Mine has also started to struggle a few times when idle.

Please let us know if this fixes the problem, as I'll probably get mine checked out too.

Your signature line indicates you have a JCW equipped Mini. Maybe this fault was a result of the kit being installed.

Bear:

The JCW kit has not been installed yet. We originally thought it would be coming with it, but the '05 kits aren't available in the US yet. So...it will be a JCW in about 4 weeks. Just haven't bothered to change the sig.

UPDATE: Molly came back from the dealer on Saturday. They replaced the intake pipe between the throttle body and the supercharger as well as the gaskets. So far, no problems. She seems to idle much better and power and gas mileage are back where they should be. We'll keep you all updated on whether we get a rough idle again.

Mine's done it once or twice now. How occasional did your Molly do it and what was your fuel consumption?

Only did it once in about 1500 miles. Fuel economy was 29-31 before...27-29 after. Now we're back up to 29-30

Me, too. Every morning at start up, as soon as it's turned over, it's starts to stumble, and act as if it's going to die, and then after 5 sec tops, it's ok. I know I need to get it checked out, but after only having it 22 days, I'm loathe to give it up quite yet. As it seems others may be having a problem as well, I guess I'll make an appointment for right after our local Oct. 3rd rally. *sigh*

CooperS4US:

Ooops...haven't been on here in awhile. Well...haven't had any rough idle problems since they replaced the gaskets and intake pipe. From what I've read on here and on NAM, we're not the only owners who have had the pipe replaced. If you've got a rough idle issue...this might be a good place to have your tech look.

FWIW...we also had the JCW kit installed in November. We've had it a little over a month now and no problems so far.

I had problems with this and I replaced my coil pack. Maybe faulty plugs?
