Long time reader, first time poster.
I've finally taken the plunge, and bought myself a MINI - a used 2008 R56 Cooper S with the JCW
kit installed. In a word, it's awesome
I've noticed a 'stutter' or sorts, particularly noticeable when the engine is cold, which I'm led to believe may be a result of carbon build-up on the intake ports. The previous owner didn't do a whole lot of kms (just over 70k), but I'm guessing a lot of that was through traffic.
Has anybody gotten the decoking treatment done on their cars in Perth WA? I sent a request to BMW, but they clearly aren't interested in the work.
I'm not closed to the idea of DIY, but if there is a reputable company willing to do it for a reasonable price, I'm happier to keep my hands clean!
