Exhaust noises (light backfiring?)
When I am letting my car idle I am hearing a medium loud puff come out of the exhaust pretty regularly. I don't really know how to describe it, my friend seems to think it's the prologue to backfiring, but I think he's wrong.
Uhh, for lack of a better example it sounds like this:
mmmmmPUMmmPUMmmmmPUMmm
Now I feel stupid x2 haha.
It is an 87 Turbo II, I figure the exhaust is somewhat clogged up, I'm gutting my cats soon, so we'll see what that does for it. Anyone have any other ideas?

There either clogged or there is leaking fuel and igniting in the exhaust. I have had a rotor go out on me and basically not igniting fuel and they would explode in the exhaust or not explode but ignite.

I am having the same problem, and was advised that it was the cat.
I also got a sound coming from the center of my exhaust, about center of my car, like a little piece of rock jumping around.
anyone else have this problem?

Also I just changed from 10w-30 to 20w-50 and the car is noticeably slower. It has lost its pickup and go. I also got the LSD fluid changed out, fuel system flushed, and the transmission fluid too.
