What Are the Symptoms of a Faulty EGR Valve in a Jeep JK?
The Jeep JK EGR valve is a component of the exhaust system that regulates the amount of exhaust gases re-circulated back into the engine. The function of the EGR valve helps reduce emissions from the engine and can help improve performance. If there is a problem with the EGR valve, it can cause a range of symptoms, including loss of power, poor acceleration, rough idle, decreased fuel efficiency and an illuminated check engine light. In some cases, a faulty EGR valve may even cause stalling when starting or accelerating. If any of these symptoms are present, it’s important to have the Jeep JK EGR valve checked and replaced if necessary.
