Aight I have my header install...

[~The_Duke~]

just take it to my buddys shop he will tell you what the problem is and if oyu already have it fixed then he will erase the cpde turning off the CEL

Well that is no fun lol

If I cant figure it out from these lil error code directions with the blinking lights and stuff I will.

From looking at the list of codes, I am going to guess that it is P0134 (Sensor Circuit No Activity Detected) which would have been caused by cranking the car without Bank 1 Sensor 1 install...

So it quite possibly might throw 2 codes by time everything is said and done?

I dont understand how 18mm long spark plug anti-fouler will trick the system into thinking that the cat is in there. Could you plz attempt to explain why? Just merely curious of how things work...
