Why did they say you need one? What was the code specifically?
Theres 3 parts to the EGR system (plus vacuum lines). The EGR valve, a solenoid, and the silver rectangular box (EPDM or something like that). That's usually what causes EGR codes. Usually something like too low EGR circ, or too much.
I had it on my truck. Replaced the silver box with one from an updated black one from a junkyard Ranger 3.0. Code's been gone for almost a week now.
