150k miles. Replaced injectors, plugs, PCV valves.
Car running very rough. Smelling of gas. Smoke coming from exhaust. Got check engine light (CEL) codes P0087 (fuel rail pressure low), P0302 (cyl 2 misfire detected), P02A1 (cylinder 2 – injector leaking).

You should edit your title to say Enclave, Acadia, and Traverse since they all have the same engine and this would be for the 2009-2012 models for sure. Not sure if the 2013-2016 models have the same engine. Thanks alot for posting this as this is exactly what my '12 Traverse was doing. Not gonna attempt to do this myself as I do not have the tools but I will hit up my local mechanic.
