Amen. Germans and GM/Ford. The Ecoboosts are baddddddddddd about carbon.The Germans for some reason seem to be having the bulk of the carbon GDI issues. Maybe if they'd use tighter valve stem seals!!!!!! Glad Toyota and Ford added port injection with GDI to avoid the carbon issue. Now there are 8 fuel injectors for a 4 cylinder! Glad Honda fixed their issue! Allegedly! Hopefully, it will be a better fix than their 5-speed tranny fixes or the their cylinder deactivation oil burning issues.
