Have 97 and 02 4.6ltr. with same part malfunction, the Exhaust valve. ( Check engine light was on)
You'd think Ford would have improved the exhaust valve by now.
How many of you have had to replace your exhaust valve? Both trucks were manufactured at the Northfolk plant.

 

are you sure your not meaning exhaust gas return valve(egr)?

 

I thought egr stood for exhaust gas recircuation?????
