I installed new Belanger headers + high flowcats + Corsa exhaust. Oxygen sensors in place (not removed).
Also I installed Mopar Gen IV upgrade for Gen III which included Heads, Intake Manifold, fuel Injectors, gas pump, PCM upgrade.
I am having some Black smoke coming out the exhaust (not so much, not visible), it increases as car heats up. The hotter the more amount and smell to gasoline coming out of the exhaust (rich mixture).
Black smoke not seen but I noted that exhaust pipes getting dirt, so I cleaned them and Black residue acumulates, totally black.
Any ideas?
