SES Light! Bank 1 too lean!

[TheRedLS1]

So I have this phantom SES light that comes on every so often.... I'm sure most people know what I'm talking about. We'll it used to be on for a while sometime back but then vanished for a couple of months. Now after a current CAT mod it seems to be comming on more often. I know I need to check my gaskets and what not but I'm lazy. And also I have a pin hole in one of my headers :mad: :cool: . We'll to ad to the story I need an inspection sticker but i need to ditch this light. i just wanted to know if anyone has run into this problem and what they did.

Exaust leaks, vacuum leaks, tuning bad injectors... That code can be alot of different problems. You say you have a pin hole in your header start there.

pin hole can be fixed with a quick spot weld.... hell i cant imagine someone charging more then 5-10 bucks...

Fix the hole and then see if you're still throwing codes.

Thanks! Yeah I need to just mess with it a little and see what happens...

Would too much oil on a K and N really mees with the MAF making it run lean???
