Fixed my high BLMs!

Not bragging here because I changed a lot of parts then got lucky. Its was the MAF sensor. Put one in tonite and went from 148 to 114. I chased around a vaccum leak forever and it was the MAF the whole time. The old MAF didnt have a screen could that have caused the problem? Also is 114 too low or should I just be happy with what I got? Now people can stand behind the car when its running :biggrin:

Not sure if you have to or not, but did you reset the computer after making the change?
The counts might come back up after you drive it awhile.
And then again, I might not know what I'm talking about.
Congrats either way.

Thanks for the input, no I didnt reset the computer I am familiar with the blms starting low after reset. They went down shortly after the car warmed up.

How do you or what do you look for to get your BLM's higher? Mine are around 116.
