Hi, new to AF so if this is wrong in any way please correct it.
I have a 03 Mazda 6s (manumatic tranny), 7300 miles on odometer. Sometimes while driving i notice excessive amounts of smoke coming from the tailpipes, more so than other cars i see. Also it appears to be at times thicker,whiter, in color than normal exhaust that i notice.
Also upon coming to a stop, the interior will bring in a strong bad smelling substance whenever the a/c is on sometimes. This is also noticable upon exiting the car, the smell sticks around. Im not to sure as to what could be causing this problem and would like to know from anyone who has an idea. If it means anything i recently had oil changed.
Thanks
