I went back to pump gas and ran a tank through...seemed to clean them up nicely.

Cylinder 4 went wayyyyyy lean (kept spraying fuel, but not enough to keep the AFR rish enough and the EGTs cool) and melted a large hole in my head and put a couple divots in my block while destroying the head gasket. Luckily, my head and block are salvageable, but by no means was a it cheap and easy fix.

Keep an eye on your injectors, guys.

stumbled home and took apart the injectors and one of them were just clogged with gunk..

cleaned them off and started the car again and the rumble is still there.
changed back to pump gas and pump map and the rumble does not go away.

i have precision 1200 injectors and they all read 2.4 ohms.

could i have damaged the head? how else can i check the injectors?
i will try to post vid on the noise.
please help guys
