Help

I have looked up several threads and have not found any help there. Plenty of solutions for high blm's but not for low ones.

i do have some exaust leaks no vacuume leeks and adj. the fuel press doesnt change anything.

is there anything i can change to get the lv8 #'s down

What are you using for a MAF? I had the same problem with my TTA, at idle the BLM's would peg low. I would also set a code 45. I had one of those junk after market MAF's in there. Replaced with good AC-Delco, problem solved. Injectors, chip can also cause this problem.
