    Thanks for the input guys. I took it to Mike John's Imports in Jeffersonville, Indiana, and it ended being the timing chain. They replaced the chain, the solenoid, and did an oil change. She's running pretty good again. It still needs the carbon cleaning, but that'll be a next month issue to deal with. :D

    Are there any codes stored or lights illuminated?

    Usually carbon build up is accompanied by hard/no start, low power, poor MPG, even misfires.

    Have you done a smoke test to check for a vacuum leak? If the issue is only at idle I would lean towards a vacuum leak, most likely the PCV hose on the back of the valve cover is leaking.

    Kentucky is just a stones throw away from us in Detroit. :cornut::D

    Best of luck,

    Hey there im having a similar issue with sputtering as you were having a few months ago, happened right after noticing a huge leak coming out the tensioner which decided to almost pop completely out. Tightened it up off course hoping it would give a chance to get the whole chain cassette replaced without any further damage.

    Only 55K on the clock and i know is a very common issue on these. Question is, did you have all 4 cylinders misfire on you? Also do i even bother going to my local stealer to see if I get some kind of coverage on this or just get the parts and have someone else do it? 4 months with the car and already looking forward to fixing it and selling it:mad5:

    There were a few that seemed to leave with the chain tensioner not being properly tightened at the factory... Sorry you are thinking of dumping your MINI...

    Yes, I suppose i got lucky. Not only was the design a total fail but we also have to hope the Damn Robot tightened that damn tensioner bolt.
