how to get rid of excess carbon build up inside the engine?
take off the 3000 pipe when engine is hot, with a spray bottle(like windex-type) full of clean water, spray it into the throttle body... dont pour it in there, but mist it. dont use a lot, i cannot stress that enough. sparingly is the key.

*disclaimer*
i do not take any blame in harm caused by this method. it will work if used as described. if too much water is applied, it will hydrolock.

you ever done a bhg job?
upon removal of head, it is instantly obvious which cylinder had coolant leakage. it looks brand new.

works the same if you have a water injection system. that will keep your combustion chambers brand spankin new.
