Only the earliest 03 engines got the throttle plate.

The way I read it from the 04 updated coffee table book is the EGR throttle plate was added in 04 and in this 05 running changes PDF https://www.ford-trucks.com/ford-man...ges-Update.pdf the 05' Excursion pre January 05' got the 04' MY engine with the throttle plate. I see after reading the 03.25 coffee table book that some 03's had the throttle plate too as it says "if equipped" so I stand corrected on the part highlighted in red

Interesting. I thought the throttle plate had a short life. Guess not.
Need to keep that more in kind when guys with the earlier engines have weird symptoms... Could be that valve misbehaving.
