I need assistance. my car is having bouncing idles once engine is warm. from x1.5 to 2. I gotten the codes of P0505, P0118. i have replaced IACV, cleaned out throttle body as it was dirty ( later replaced PCV as it was gone and getting the throttle dirty & given some type of liquid.). After replacing these things i went to get my code checked and scanner wont read codes anymore but check engine light is still on. I have done the smoke test by the vacuum hose leading from drivers side to intake manifold ( smoke come out of air intake.) So im at a loss, i dont know if a vacuum leak is still possible or are my fuel injectors bad?. any help will go miles at this point.

this what the inside looked like before i replaced the PCV
