MAF is clean, i recirculated the BOV after installing uicp with tial. still CE came up, it looks like it comes up quicker when step on the gas and hit full boost up to red line while driving...

today i will check, injectors, o'ring on maf.

I will keep you guys posted.

 

i have a 9, i had this problem ever since i had a leak at my o2 housing...fixed the leak but still having system lean code thrown...i have an exhaust leak as well, so i will be fixing that first to rule that out. Might possibly be intake or o2 leak still, will check all piping, fix exhaust leak and will update back.

 

cool let me know , im thinking bad maf, now CE comes up right away after a mile. Im pretty sure i dont have any exhaust leak.

 

result was just the exhaust leak. There are 2 different system lean codes. group 1 and group 2. depending on the group, it can eliminate a few different things. In my case, this was just the exhaust leak that was throwing everything off. I didn't even have to clear the code it just went off on its own after sealing up the exhaust.
