Hello to you from Seattle, Washington state, USA. It is never too late to buy a Pico.  I dont have one yet myself. Tom has a video here, I forget it's name that involves a repair for an American vehcle what had a misfire since the day it was purchased - for just a few minutes after start-up. The dealer could not find it nor could any else. The Pico scope made the difference. It is an excellent sales pitch; this video.
   I believe it was Tom and a partner found which cylinder had the misfire easy enough but the cause was a compression issue they found - using a pressure transducer hooked to scope - that occured only at startup.
