  1. Dodge Nitro Mechanical Problems and Questions
    So as much as I love my Nitro I keep my maintainence up for longevity. Go to the mechanic to replace sensors, and I discovered cylinder 2 is misfiring and the spark plug tip(the white part) is half gone. Plus not to mention that cylinder 4 was starting to misfire so I’m wondering wtf is going on...
