Ok. I've having this problem already for a while. Took it 3 times to a dealer. Last time they have replaced BOTH MAFs and it just came back today. I am running with stock air filters and charcoal filters in place. What could be the problem? I feel like dealer has a very little knowledge in this matter and I was wondering if you can suggest me to guide them to the right directions. Thanks.

Have them check your intake manifold gasket.
