I recently cleaned the throttlebody, so I will check for the EGR valve instead. It’s common for this to happen without the engine light on with this amount of Mileage? I think last month I got an engine light indicator but the code gave me “MAP Sensor”. I check and cleaned the sensor, then reset the ECU and till today no engine light for me.

Does this valve easy to replace? How can I check for malfunction on this valve? Approximately how much should it cost?
