I started my car up this morning and as soon as I hit the key my car let out a huge bang from the exhaust. Definatly ignited some fuel. It was pretty cool actually. my mom thought someone shot me.

Car runs fine still and has never flooded. Maybe this is the begining sign of flooding.

 

Could be. I did that once starting my car after the Haltech install. Scared the CRAP out of me

 

possible leakey injecters

 

this happened to my brothers engine when he went to move his car... also his rear rotor... apex seals were blown.
