A buddy of mine installed some headers on his '00 lude last night, and now the car smokes white kind of bad, and after driving for about 15 minutes the header turned a crazy gold color. Also the CEL is on and it the code is for 02 heater circuit. Is any of this normal? will the spark plug non-fouler work for the o2 code?

 

did u plug the o2 back in the bung when u installed the header?

 

Yeah, it's plugged in.

 

what kind of headers? When i installed my catback they said dont worry if it smokes for a little while it usually is the oil and flux and whatever else is left over from manufacturing.
