  1. I jus pulled the intake off and manually cleaned followed by walnut blasting then crc gdi cleaner. Came out looking brand new in the ports. Of course you have to roll the engine over to get TDC compression stroke for each cylinder so it’s one at a time and very messy when all said and done but we’ll worth it for the GTDI engines. I was chasing a cold miss fire only on cyl 5 . Now to run a methanol injection kit and never worry about it again lol
