More information is needed to answer this question properly, such as; is the engine a 4 or 6 cylinder. In the case of a 6 cylinder, their are 2 exhaust manifolds; the front exhaust manifold is located under the hood between the radiator and the engine: when you check your oil level by grasping the dipstick your hand will be just a few inches above the exhaust manifold. Basically, follow the exhaust pipe(s) to the engine and where it connects to a device that splits the exhaust 3 or 4 ways, that device is your exhaust manifold.
On the right rear of the exhaust manifold ( behind the exhaust manifold) , you will have to turn the engine to get to it . (* check out chilton manaul for 98-? for vans and trucks .
check for exhaust leaks around the manifold inlets and outlets.
Yes
your oxygensensor is bad ,its screwed in to your exhaust manifold, about 30.00
It could.
have a mechanic check your turbo.most will tell u that a turbo blows black smoke but can aslso blow white smoke when turbo is malfunctioning
Yes, it can affect the oxygen sensors and catalytic converter.Yes, it can affect the oxygen sensors and catalytic converter.
The Oxygen sensor that typically on MOST vehicles is the one closest to the heat of the exhaust. Since the SL2 is a 4 cylinder engine with a single exhaust manifold, check (or replace) the FRONT oxygen sensor, which is in the exhaust manifold, just above the "headpipe". It looks a little like a sparkplug, and should be the only thing in the exhaust manifold that has a wire connected.

check your engine for a cracked manifold (covering of the engine parts and cylinders. also look for any exhaust leaks. it sounds like the exhaust noise isn't making it to the muffler as it should and instead is coming from the engine directly.
This sensor varifies flow of the exhaust gases to the intake manifold. If flow is interupted the sensor will inform the onboard computer that the exhaust recirculation system has failed resulting in a check engine light to come on.
