if its for an obd1 car i would get rid of it

its strictly emissions only item and is not needed with a performance build in mind

most older cars charcoal canister is ruined due to people over filling their gas tanks for the past 15-20 years anyways

Keep in mind if you get an inspector that gives a crap it will not pass the visual emissions check for inspection.

Yea but if a mil is thrown its because a monitor cant be completed for a certian system and goes to open loop…
