Well... it certianly sounds like knock -- pretty bad knock if you can really feel it like that. You should datalog and remove ignition where the knock is at. When the MIL flashes because of knock, no code is stored. The only way to identify knock that causes the MIL to flash is to datalog and monitor knock count.

You need to tune the AF for your setup - the long term fuel trim is at -17% and the car is running very rich. There is knock but the datalog does not show where.
