Thread: Went to Star Nissan Today.

you get a ses light from removing the header.....i did......you have to buy a fix for it and put it on the midpipe....it never came back for me....i think i used a spark plug spacer

blackoutsped, im sorry but did you read my post in the begining? I have had the header for about a year and a half already, and the light just came up NOW. Ive had the spark plug defouler, aka 02 Sim ever since i put on the header. I dont think i mentioned that part yet, but i figure if you have a spec people would know by now that if you put on a header on the car you should put the 02 sim automatically.
