Im rounding about 60k miles on my car now, and I bought it last year with 35k, so besides the one caliper issue I had originally about 5 months ago, even then I never had this weird growling sound. But its very random, I don't remember hearing it at all this morning. But like I said, its only about every 2-3 times out of 10 it makes the noise, but it sounds horrible.
I still plan on taking it all apart tomorrow, see if there is anything obvious. As of now im just preparing to buy that list of parts I posted a little bit ago when I get paid again.
Im starting to feel I wont ever get around to doing Meth on this car because I have about 10 other things that need to be done first. I might as well sell my MyCal tuner and just keep the SCT on the car like it is now.
