Hi All,
87 Sentra fails smog. HC CO gross polluter NOX okay though. So I take it to a smog specialist and find out that the AF mixture solenoid is not working at all. Puter sends signal but valve refuses to move. Now heres the kicker, they estimate that to put in a rebuilt carb and adjust it would be about a grand. Ive read on these forums that the carb is tricky to rebuild and adjust but a thousand dollars is not worth the effort. So I start to read the FSM and there is a section which spells out how to change the AFR mixture solenoid. It appears one does not have to rebuild the entire carb to change that one part. Am I not correct in that assumption. I appreciate any responses and suggestions. TIA
