Seams like I finally got a cel after three months of no problems with my header. I am suspecting thats the cause of the cel, but i will see if i can get it scanned . The only other recent things I did was install a catch can and poly motor mount....Oh i also tried to clean up some of that nasty rustproofing in the engin bay.....could have got water into something i shouldnt have but it took a day for the cel to come on......I reset it once, was good for a day and now its back! Any thoughts ?
