MAC MASS AIR SYSTEM Problems....trips Service Engine Light

[DeathWish]

I have the MAC straight shot. Everything was running fine for a few months, but recently my Service Engine Light keeps coming up. If I disconnect my battery, everything seems fine, but after some driving ( a few days usually) the light comes back again. The codes say that my car is running LEAN. I check and checked to see if there is a leak or anything. Everything looks good. Then I remembered that I washed the engine bay of my car a while back. I was very careful to cover all the areas. Maybe some of the water or degreaser or something might have messed anything up? I was told that maybe I should check the Mass Air Meter to see if it is dirty. How do I do that? Where is it? Please help....

Its most likely your MAM. I hear a lot of people having problems with MAC meters because they reuse your stock electronics which tricks your computer and causes your car to become lean. This also happens to people with C&L. I would put your stock MAM back on and see if the problem goes away
