i have a 2005 rx330 that’s experiencing a lean condition. Once the engine is fully warmed up light acceleration brings on the death rattle. I pulled the plugs and the porcelain is white/light gray showing a lean condition on all cylinders. I was thinking bad pressure regulator or a clogged filter. Anyone else have this problem?
