exhaust leak

I have a check engine light on, wondering if a bad exhaust leak can trigger it? Don't know of any other possible obvious causes. She doesn't run hot, exhaust smoke isn't black or anything, starts on a dime and runs great with good compression. Oil level is good. Hmm. What about oxygen sensors?

On startup, and maybe a little bit at idle, I'm getting an exhaust smell in the cabin. I looked around and couldn't find anything, and so eventually took it to a shop where they smoked it. They claimed they could not find a leak, and so I am back to square one. Any ideas, something that could...

Seems like the exhaust is leaking from somewhere where the cat seals with the rest of the exhaust. I bought a new gasket for the rear of the cat and a new sealing ring for the front. I cant tell from the bentley but does the cat just drop out once its unbolted? or will it require moving the...

Hi everyone, A couple days ago a mechanic replaced the transmission in my 2006 Saab 9-3 2.0T with an used one (Thread: http://www.saabcentral.com/forums/showthread.php?t=550561 ). I picked it up a couple days ago. Yesterday I heard a strange rattling upon accelerating (not on idling), so...

I replaced the intermediate pipe... meaning its welded on to this whole piece (mechanic welded on). I don't know how to weld and...

I just noticed a few days ago that there is exhaust noise from under the drivers side when the car is first started. I just noticed it so I scheduled an appointment with the exhaust shop in town. But yesterday, after my daily commute I noticed that there was no exhaust leaking noise. It seems to...

Hey guys, I have an exhaust leak coming from the intermediate pipe in my exhaust system. If anyone has one for sale, i'd be very interested. Just for your knowledge, I would prefer using paypal.

While a friend had my 9-5 wagon over the summer (I work on boats in the summer and ski industry in the winter) it required a new oil pan, maybe she hit something, maybe the oil pan drain plug was over tightened. Either way: pretty blond girl brings my Saab into 'the only shop in town' that...
