Is it a good idea to remove the screen on the Mass airflow sensor on a 2000 Chevy Blazer?

There are a few reason this might happen. If the aftermarket intake has a different diameter on the piping the MAF sensor will need to be adjusted via the ECU (re-scaled). If this is the case take your car with new Intake to a professional Subaru Tuner.

In addition if the MAF sensor is dirty and the new intake is flowing more air you might get a poorly runing engine and/or ECU throwing CEL (Check Engine Light) codes. If this is the case clean your MAF with electric circuit board cleaner (make sure it won't leave a residue) and reset ECU.

Good Luck.
