Rpm low and asap hitam keluar from ekzos

[cheap_s2]

Salam sifu..my e36 no problem at all until i rasa kurang selesa dengan gear shifting(auto) bile lepas minyak gear akan shift then tekan minyak balik dia seperti pickup n now prob dia bile i slow di junction or toll rpm akan jatuh bawah satu xstabil and asap hitam start keluar dari ekzos then kalau dia dapat balik tune dia akan kembali normal..selalu i akan letak di neutral and ramp sampai die ok balik..boleh bagitau apa masalahnya sifu?

when idle how's the rpm? also up and down? mungkin AFM problem.

Very likely Air Flow meter....It happen in my car and have service it then OK

AFM need to be serviced.

erratic idle and car sounds like motorboat when rapid acceleration - a sign to service your AFM. there's thread on how it can be done
