A rattling of sorts, Exhaust?
I'm only posting this here wondering if anyone has had this problem or knows what it is, I'm really not trying to diagnose it as I have so many other issues going on atm that I can't add another problem to my plate, and I don't think this is terribly serious.
Anyway, every morning when I leave I have to drive up a fairly steep hill.
When I start going up the hill, the car will shift, and the TC locks up at which point, around 1500rpm I hear this odd rattling noise, sounding like some metal flailing around in my exhaust or something.
It used to do this out of gear, when I would rev the engine, around the same RPM range. Now I only ever hear it when going up this hill or basically I guess when the engine is loaded down.
I suspect cats, or exhaust something or other, but I just wanted to know if anyone knows anything.... maybe something has come loose in my cats??
I'm not ready to pull my exhuast system off to go looking inside at this point, but its been going on for a while so I would like to have some idea.
there is no loss of power or any effect other than noise that I can see/feel, so i don't think it's detonation.... not to mention that it doesn't sound like detonation... it sounds really tinny.
