i know you guys are good

Since i am pretty new to working on rotaries, and i cant always spot issues as easy as i can on my other car, i need some help. I read the fsm about a million times, but some of the diagrams suck.

The car: 91 (s5) non turbo
Only mods include new magnaflow direct fit cat system (single 3 way cat), corksport catback (2.5"), and cone filter replacing the airbox ( mini filter on the air pump intake tube). Premixing half to one. Completely stock otherwise, supposedly. I am replacing the O2 sensor today if i can pick one up from autozone.

The symptoms, related or not:
The car sometimes has issues staring cold. It will almost start immediately, then not and i have to flood start it which it tuen starts immediately. Oil doesnt smell like fuel or seem to be breaking down (doing uoa this saturday when i change it).

When the motor is warmed up, and i just start driving even with a sligjter heavy foot, and i come to a stop, i smell fuel. It goes away after about a good 15 minutes of driving in rull warmup.

What i have seen that may be odd:
The charcoal canister, has the two upper tubes that go to the fuel lines/evap system, but there is one coming out the bottom going to nothing?

This pictire is right below the throttle body:

Should those two capped nipples be going to something? Should i replace the caps? They appear warn and cracked.

Your guys help is appreciated.
