Hi 86forums members,


I've been having issues with my 2014 Subaru BRZ, where during normal daily driving, the engine makes a horrid sound and loses power. I have no idea why the car is doing this, the car is completely stock. I think it could be a misfire and I hope it's not knocking. It happens at random usually when I accelerate and happens usually once a day. Sounds like a pop sound but from the engine, followed by power loss. I managed to prompt the issue with Torque App monitoring, but no codes were shown. 


Sorry if this thread already exists.

How many kms ? MT Auto ? History of vehicle?


Sounds a bit like DI seals but it's a 2014 . . . .


Video would prove more. Check airbox is closed shut & properly, no leaks. Check tightness of air intake tubing from air filter etc, make sure all tight.
