Cl type s running rich

I have a 2003 Acura CL type-s 6speed. Been having issues with every cylinder misfiring, plus random/multiple misfires. Ive cleaned the intake manifold and replace every gasket to it. Fixed a vacuum leak but still running rich. Stft and ltft running around -8 to -10 at idle. Also can hear 1 misfire. Need some help here.

Just replace all gaskets from the bottom of the runners up. New orings on both sides of the injectors plus 2 of them replaced with new injector. No missfire but still running rich.

Any update on this? I have the same problem, the CEL always reads multiple cylinder misfires. I've replaced almost every thing to do with the fuel system, and it still runs rich.
