2006 tacoma, 2.4 L four cylinder. Check engine light on. Strong smell of exhaust fume with a loud rattle or knocking sound coming from underneath toward front. Loss of power, esp. When attempting to gain speed quickly or when driving up inclines. Could this be bad plugs? What is the knocking sound?
have the same problem?
