Does a 2003 Tahoe 5.3 have an EGR valve?

Is this the dumbest question of the week?

I have been doing some searching including a quick review of the online Chilton book and I can't find anything defenitive as to whether or not my truck has an EGR valve. I have been experiencing a rough idle and am going to do an oil change and maybe plugs this weekend. While I am in there, I want to check any other little things too.

Any help appreciated.

Some do some dont, if yours does it will be on the pass side and have two bolts holding it on, there should also be a sticker on the cover above the grill showing which smog parts are on your tahoe
