Review on Dorman 911 128 EGR Vacuum Modulator by Patrick Ross
DO NOT BUY THIS! fits spares
I put a new modulator in my car and the car ran absolutely horrible it was causing misfires in 3 different cylinders. I was trying to figure out what could be causing my car to perform so poorly after installing new parts. It never occurred to me that the problem was with the new modulator until a few days later I had the idea to put the old modulator back in and the car ran absolutely perfectly. I was just trying to get rid of my EGR DTC and that part only made things worse.
