I dont know if this is a silly question at all but does running cat less affect the MAF? I ask becasue this will be the 2nd MAF ive went through in less than year. First one was bout 3 months old. Second i got used from a friend lasted about a 2 weeks damn p0171 so does my exhuast have any affect on my MAF.
