Q: Check engine codes

你好呀：

It’s possible that simply fixing the exhaust system will clear up the issues you’re having with your vehicle. However, without knowing the exact codes triggered, the make, model and year of vehicle; and without completing an onsite inspection, it’s hard to tell you exactly what to expect. You may want to have a mobile mechanic complete a检查发动机灯检查因此，他们可以充分检查所有代码及其原产地点，以确定哪些维修应解决您的麻烦。
