OK, I've read a lot of posts regarding the moosing common to our SVTs, but nothing fits what I have going on. I had the nose cap on my filter fall off during normal driving, but I don't know how long I was driving with it like that. I was getting a moosing type of noise so I investigated it and found the tip had fallen off. I was going to glue it, but I just went ahead and replaced the filter. Now I am still getting the moosing sound at certain RPMs and especially when downshifting from 5th to 4th at about 50-40 mph. Never had the problem before the filter issue. I tried cleaning the MAF wires according to one post I found and though I got a small amount of residue off, the problem remained. What is going on and is it repairable, or do I just need a new MAF? Please help!!
