this morning im driving home and my speedo is dead. everything else works. and speed starts goin crazy ... acting like an afr guage basically.
I got a CEL and its code 41.
i have p28chipped b16a2 obd 2 to obd 1.
on ht it said primary oxygen sensor heater
*ALSO my volt meter goes from 13-14volts ..keeps going back and forth and the CEL light also goes dim than brighter again, if its an emissions problem why is the power acting weird.

could be an electrical problem as well causing the code, check your grounds really well before you go doing anything else

not really. I paid wat a alternator costs from dealer plus 100$ to install. and by the way it wasnt the alternator so he didnt charge me. I found the problem. thanks bruno
