I have a 98 Burb 7.4L V8 and it is running like a champ! I just rolled over 90,000 and had spark plugs, wires, PCV, O2 Sensors, and oil changed. I am wondering if I should have the EGR valve changed? Nothing out of the ordinary is going on, I just want to make sure it stays up and running great.

 

Welcome to the forum...
I wouldn't replace it if its not giving you any problems, you could however, pull it and clean any carbon build up on it...

 

I would leave it alone if it's running good. You will know when it becomes a problem, IT WON'T IDLE AND WILL RUN AWFUL. JMHO, good luck
