My car has a manual transmission.

Hi there. I understand your confusion. It may be advisable, to find another repair facility. The exhaust smoke (black in color) is typically, an indication of too much fuel being delivered to the engine. This may be, the result of a faulty fuel pressure regulator. The dirty air filter, would of been another possibility, had it not been recently checked. I recommend having your vehicle’s black exhaust smoke be diagnosed and repaired by a certified technician, such as one from YourMechanic.
