Will this cause this??
ok I have been having this issue w/ my exhaust even before I put it away last fall. I had to remove my Y-pipe because I had to replace the oil pan. Well when I reinstalled the Y-pipe to the manifold it would not seat and tighten properly. So I got it the best I could and left it. Well after that I have the SES light come on for lean exhaust gases. Now would the lose manifold cause this? The part of the Y that is lose is on the O2 sensor side. So please let me know if this does cause this or not.
Also I'm looking for a set of headers lem know if u have a set that u wanna dump for under $150
Thanks
Jason
