xe2dy Posted February 25, 2020 Report Share Posted February 25, 2020 Hello, looking for "SWIRL CONTROL VALVE CONTROL VACUUM CHECK SWITCH" for a 1984 NISSAN 720 Z24. Item is identified as SPDB28-58. My pickup failed the California smog test and the mechanic told me to replace the switch. The Carbon Monoxide was too high indicating rich mixture. Problem is I've had a very hard time finding one. Please help if you can. It hurts to think I will need to scrap my Dad's truck if I can't pass the smog test by March 31 2020. Quote Link to comment
