Tons of false knock or soon to be dead motor?

defury · 02-21-2020, 08:19 PM

I recently had my car in to replace the old rubber fuel lines under the intake manifold and had plugs and air filter replaced at the same time along with intake manifold gasket. The reason I start with this is maybe the ECU learning was reset when the battery was disconnected?

Anyway I have a JDM Forester cross sport with the EJ205 with AVCS and I recently installed a OBDlink LX and BtSMM to monitor the car and I was shocked by the amount of knock I was getting at extremely low load/rpm/no boost.

The list is the knock events as I wasn't logging at the time, and this google doc is me driving while logging after letting the car sit for a bit. thoughts? Do I need a tune ASAP? I'm running 94 octane atm.

The knock list was before the log
