I smell exaust throught the vents when driving my 97 escort.
I smell it mostly when idling, not as much when the AC is on.
Is this a serious problem (like could I get sick from it).
This car supposedly passed through emisions. Did they really
take it through, or is this some used car scam? and what
could be the problem/soultion.
Cars can pass emissions tests with leaking exhausts.
Exhaust smells can lessen during AC operation if the AC is
in its recirculation mode, not letting in outside air.
The car has an exhaust leak; could be a blown exhaust
manifold gasket, a loose pipe connection, or a hole in the
exhaust pipe or muffler.
It is a dangerous condition; you probably won't die from
asphyxiation; you are more likely to just become drowsy
and drift into a head-on collision with some innocent driver.
Consider your family and fellow citizens. Get it fixed.
