这P0302 code is showing. The spark plugs are good - my mechanic checked them. At low speeds, in town, the car literally goes putt-putt-putt. I want to have the IAC valve changed. Do you think that's a good idea?

你好。这P0302 diagnostic trouble code表明在圆柱2上检测到失火。spark plugs,,,,火花塞线,,,,点火线圈检查或点火控制模块。这可能会解决问题。如果您没有获得IAC阀的诊断故障代码,则可能无需更换。P0302故障代码通常通过在车辆上完成调整来解决。请记住,有时此故障代码是由喷射器故障,,,,burned valves, or a dead engine cylinder. I would suggest that you have an检查失火状况completed by a certified technician, such as one from YourMechanic.
