This one was a tough one to nail down. We received the vehicle after it experienced a “Parts Cannon” event elsewhere. +30% LTFT, P0300-C7 - Misfiring Detection P2096-C0 - Post Catalyst Fuel Trim Sys B1, no misfiring but Mode$06 showed a handful of historic misfires on cyls 1 & 2.
We checked for air leaks, exhaust leaks, lambda sensor calibration (the new sensor they installed was fine), and we gained the perspective we needed to pull the injectors after running a cylinder balance test (Injector kill) and found that our stand-alone LAMBDA sensor peaked higher when cyls 3 & 4 were disabled.

We’re currently taking a run at performing ultrasonic cleaning of the injectors and will post up a new video with our findings.
