Hi, I've had my 4TR 1992 3VZE for 5 yrs and running smoothly. However, when I first got the car, the EGR valve was disconnected. But still astonishingly, the car was, and, has been running ever so smooth. The question is, I'm thinking of replacing the EGR valve, to improve performance. I'm scared it won't run perfectly as before. Any comments???
