Gunk in oil and severe back pressure

Fiat Punto 02 reg
Super easy to follow the instructions. Followed it step by step. Wasn't 100% sure at first because symptoms still showed after the hour. After the engine cooled the next day I drove it as normal and it was perfect! No back pressure. Cleaner oil cap and it seems to be running more fuel efficiently with no more misfire. Great product would definitely recommend it!
