Its very very common to do a OBD1 conversion on S52's because of tuning. Especially where emission testng is lax or non existent. In my state you'd have to have the cat and pre/post sensors in place or its a full stop you don't pass,,, If 98 had pre and post cat sensors, You probably need a OBDII wiring harness and put the sensors back.. If your testers look for them.. __________________
