So about 3 days ago my idle started to drop. It usually sits around 1.5k and sounds healthy. It then dropped to around 1.2 than to 1k now it has made it to under 1k where it is barely able to stay running. I smelled the exhaust and it has a very strong smell of carbon monoxide. Would that mean it is running too rich? What would you guys suggest I start changing first?
Also it is 00 zx6r. thanks
