I have a 1996 Ford Explorer and it idles rough. I have replaced a EGR tube seal and it helped a little but still does not idle correctly. Can anyone give me some suggestions on what it could be?
Replace the upper intake gaskets and see if it fixes it. Sometimes you have to replace the lower too. They leak and cause a vacuum inside that you can't check. Made out of rubber o rings.
do you have a engine light?
