is there any company that makes o2 sims for an lt1 with obd1.

thanks,

No, because O2 sims are only for the post cat positions so an OBD2 car can tell wether the cats are missing or dead. The front and only O2s on OBD1 are used to allow the computer to modify fuel trims, they are a good thing and without them you might as well run a carb.

 

well someone replied to my post about single cat headers and Y on a dual cat car and said id need o2 sims for the rear o2s.....since i have a 95 i wont need them?

 

Correct.
