    Unhappy 2002 wrx with sluggish problem

    Hi my question to everyone is i have a 2002 wrx with an aftermarket blow off valve cold air intake and all of a sudden it is not sounding right and my wrx seems to have lost some of its power, it is sluggish. Does anyone know what might be the problem with it. The blow off valve is still working but know sound and the cold air intake i cannot hear it taking in air. the weather just warmed up in this area and my car has 66 thousand miles could the weather play a part in this

    First take off the aftermarket blow off valve,and the cold air intake.There no good for the WRX.Then read all the FAQ's before you mod your car.

    your MAF sensor is the little black thing with wires coming out of it on top of the cold air intake. unscrew it and put it in a plastic bag with brake cleaner and shake it up and screw it back on

    if you want an intake, get one that won't mess with your MAF sensor without a tune.. like an SPT intake. most other aftermarket intakes will screw your air/fuel ratio up without a protune.

    Do not use brake cleaner on the MAF or put into a bag and shake to clean. Have a look at this thread to see how to clean the MAF safely: $5 and 5 minutes to a better running car :)
