First off i like to give a big thanks to everybody at BlazerForum.com. Ive managed to answer most of my questions over the last few years that i have owned my truck just by searching this site. Thanks for the help.

Now down to biz. I own an 01 Blazer 4.3L 4wd 4dr with about 106,000mi on it. This morning when i fired it up the cel came on. I pulled the codes and got p0452 and p1415. I understand what the secondary air system is.Quite some time ago a had a different code for it, dont remember what it was off the top of my head but a new fuse fixed it. What i dont know is what thisbank 1 part of it means. As for the p0452 at the moment i dont think i want to lay in the snow to drop the tank so my question is could a vacuum leak cause both of these codes. If not could you guys tell me what you think and would you do. Thank you!
