Do you still have the stickers on the bottom of the hood that show emissions info? Is there ant reference to an EGR on them?

I'm telling ya, I looked high and low for that EGR valve... I searched everything going into the intake, and tried to find it coming out of the exhaust pipe, with no results!
I looked under the hood, and there was no reference to the EGR valve at all... and it even showed all the vacuum lines!

I suppose I could replace the plugs. I think the wires were supposed to be top of the line "lifetime" grade. I just re-gapped the plugs the other day.
