Hi. I just put a k&n cold air intake and a flowmaster 40 series exhaust on my truck. It is a 97 gmc 1500 ext. cab with a 305. For some reason it keeps on blowing the eng1 fuse. I unpluged my mass air flow sensor for a week and it never blew the fuse. I bought another sensor and it still blew it. I dont know if I have to by a hopped up mass air flow sensor for the k&n. Thanks for your help.
