Can this vac line cause bank 1 Lean?
#12
the o2 sensor looked fine. no dark coloration. looked "dry" if thats a way to describe it. bought MAF cleaner today as one last chance of hope before ordering a new MAF. or is it bad to go used MAF?. ECS is showing new MAFs ($144.84)ncheaper than remans ($183.57). is there reasoning behind it?

MAF cleaner is a gimick. It's just glorified electronic parts cleaner. You can't magicaly fix a toasted maf element with a spray. The only time it would be useful is if you over oiled an intake filter and it caused your otherwise good maf to get fouled up. I wouldn't trust a used maf unless whoever is selling it offers a DOA (dead on arival) guarantee/return policy.

so the final fix seemed to be a new MAF... also found the check valve above the airbox rotted. replaced that first to assess what really fixed the boost problem. just posting back for anyone else that runs into this problem to see the solution
