Well after the recent upgrades i got a bug i can't work out. The Maf fuse in the fuse box under the hood is constantly blowing now. I replaced it 6 times in a 8 hour period today. One time I put a new one in, backed up no more than 30 feet and it blew again. I can't figure it out. I have checked for faulty wires but can't find anything. Anybody have any ideas or ever dealt with this problem??
