If you suspect that the exhaust leak is causing your engine to run rough at idle, then consider taking your car to the mechanic asap. The exhaust leak can cause a rough idle if the leak is present close to the oxygen sensors The common places where exhaust can occur are exhaust manifolds, flex pipes, and exhaust manifold gaskets. Yes, a bad exhaust can cause rough idle by disrupting engine backpressure and airflow Engine performance and idle stability may suffer as a result. An exhaust leak can be hard to find and difficult to fix, but it's worth finding out if it's the source of your problems
If you suspect that your car has an exhaust leak, start by taking a look under the hood and listening carefully while idling in neutral.

Anyone know how small an exhaust leak can be and cause erratic idle
I was kind of unsure about doing this because the in. Make sure if you see white smoke coming out of your exhaust after the car has warmed up, you may have a head gasket leak or a blown head gasket Also, if your coolant is leaking, looks milky, bubbly, or you constantly have to top it off, you probably have a leaky head gasket. Going to change out the exhaust gaskets today and hopefully fix the idle issue Ran seafoam through a vacuum line yesterday and it looks like it's leaking between the end of the manifold and the pipe that's bolted to the side of the tranny. If the leak is anywhere between the cylinder head and the o2 sensor (actually, even a little bit past the o2), then, yes, it can
It throws the o2 sensor's reading (and, therefore, the fuelling) off Cis, while quite reliable, is extremely sensitive to intake/vacuum leaks Check (or just replace) things like.
