If you’re noticing black smoke from your exhaust, your engine may be running rich (burning too much fuel compared to air). That can happen for a few reasons, like a clogged air filter, failing sensors, fuel injector issues, or timing problems. Getting it looked at sooner rather than later can help prevent costly repairs.
