Hi guyz...After I fixed the Pro-Maf (77mm with K&N Filter) the car is shutting down in idle and the rpm keeps dropping down, I don’t know why? When I reinstall the stock Maf the car runs perfectly with out any problem. Any commets..Thanks

aftermarket maf's aren't worth the hassle. the stock one runs fine. you have to tune your car with your Pro-Maf. keep it off the car until you get a s/c with a tune
