Question about 2006 Subaru B9 Tribeca
I would be concerned that this issue is serious. Given all the parts that have been replaced already.
First get a leak down test performed to narrow down a possible cause. Both sides of the engine will require this test.
this will help determine a course of action
Here is a list of possible causes:
1. a plugged or restricted catalytic converter(s)
2. carbon buildup on the valves causing them to not fully close
3. issues with the active valve control system
4. less likely but possible the timing chain might have skipped

Hi! I've owned a 2013 Tribeca for over a year now. I purchased a bluetooth OBDII reader and use Torque Lite on my android smart phone to read and understand the codes. You can also clear off logged faults. I was on the freeway this summer and got a worrisome transmission error code, checked the code, cleared it, turned my car off and back on, everything was fine. If someone recently changed your sparkplugs, they may not have re-attached something properly. You can try removing the negative/black cable off your battery for 10 seconds then re-attach it securely and see if that resets the code at all. If not, take it back to the mechanic that changed your plugs.
