Can someone tell me where the EGR valve is located on an 89 Mark VII 5.0 ho ?
I'm trying to fix a surging idle.
Thanks

First try cleaning your iac valve ,its by the throttle body,yap the two nuts off and clean it with carb cleaner,for the egr ,you can clean it too and see if it is still moving,pull vacuum and see if the diaphram is working and if it is squeaking try getting a little shot of pb blaster to free it up

the aic is right in front of the air hose its easy to replace
