throwing p3030 code
And also I get put into Limp mode. this is occurring with more frequency,, about 4 time in the last week. Happens with a miss fire when hard acceleration.my mini is 2011 S model. Question is this? I the misfire likly to be from a plug or coil problem or a more serious issue like carbon or maybe hpfp. I can mannage the coils or/and plug issue, but beyond that i guess it wll be a trip to the dealer (about 150 miles). thanks for your thoughts

Yes, it's a misfire code. Good suggestion to switch the coils around and see if it follows the coil. When's the last time you did routine maintenance on the car? We have a good maintenance kit here that may be useful if it's time for these items to be done. Otherwise, if it's a bad coil you can pick up some here. Let us know what you find!

Swapped out the plugs. #3 had a bit more carbon buildup at the tip than the others. Strange part was an ultra fine thread of carbon that was bridged across the gap? New plups also studered a few times until the engine reached temp +200. Everything felt great after I got the temp up!

Real carbon cleaning requires pretty hard scrubbing. The walnut shells do a very good job of that, or you can get in there with picks and various instruments and scrape as much crap out as you can by hand.
If you want to verify whether or not you need the cleaning, borrow or buy a borescope. There are some pretty inexpensive ones on Amazon, among other places. Pull the intake apart and then slide it into the manifold until you get to the valves. If you're completely grossed out by what you see, you need walnut blasting.

That's not carbon cleaning. That's a placebo. (OK, not quite completely, but it's no substitute for real carbon cleaning.)
