I just plugged my tester into my 1995 Ford Ranger to see why the check engine light is on it came back as "EGR flow insufficient". So what part do I need exactly? Just another EGR valve or is there more to it? I no absolutely nothing my vehicles BTW.

Locate the EGR Valve and clean it with carburetor cleaner, don't forget to disconnect the (-) negative cable on your battery. That should do it. Unless it's really bad you may have to purchase a new one. Best of Luck!

Most common problem is DPFE sensor & silicon hose's attached to DPFE sensor. The silicon hose over time decays from the heat of the exhaust and allows a white powder to become dislodged from the hose & clog the DPFE sensor, therefore not allowing it to detect flow. Sensor & hose's both need to be replaced if it is the case. Finding a suitable vaccum source that can reach the EGR valve with the engine running can test the EGR . It should all but stall the engine if vaccum is applied to the EGR at idle.

You may not need any parts. NEVER replace any part till you know the problem. The egr valve may be dirty or the vacuum line or electrical connection may be at fault. The valve needs to be removed and tested and cleaned. They are quite expensive so handle carefully. Some are vacuum operated and some electric. I don't know which you have. If you take the valve to an auto zone store they will help you with it. If you drive there they can show you where it is located.

1.The DPFE (differential pressure feedback EGR) sensor is faulty and needs to be replaced
2.There is a blockage in the EGR (tube), most likely carbon
buildup
3.The EGR valve is faulty
4.The EGR valve may not be opening due to a lack of vaccuum

Fords have a solenoid that activate the egr valve.

the pintle may also be stuck. take the egr off and see. if so, get some aerosol injector or carb cleaner and try soaking it. if you can get it to move freely, you may have just saved yourself the cost of a new one.
