Yeah yeah I get your point, very funny ha ha
It's just basics really.
First step is finding out what is actually happening, measuring / monitoring etc. Next step is to remove / rectify the cause of the problem and that can only really be three main things, fuel, air or operator (often harder to remove the latter).
As for the 'fix' there are quite a few, not rocket science, it's just a matter of knowing what's causing the grief.
Finally, working out how much damage you have already done is the hardest part. Is it just "one exhaust valve" or worse......?
None of this is complex but to monitor properly and fine-tune, somewhere around the $1500 - $2000 mark.
