My car failed an emissions test.
Your truck can fail an emissions test for a number of reasons. If I knew the results of the inspection I could give you some common causes of this failure. If the vehicle failed the visual check then there may be a part that is missing or not functioning as designed. If it failed the HC test then it may have a misfire or a failing catalytic converter. If it failed the NOX test then the EGR system may have a problem. A mechanic would need to know the results of the test in order to know where to start the diagnostic process.
