Thanks to all for the good advice. I think I may try a bottle of AutoRX when the next oil change cycle comes up.

When the Ford dealer did the whole valve cover, isolator bolt fix a few years ago, would they have also done a PCM flash? My mechanic says that it would have been part of that job, but the dealer would normally have put a sticker under the hood somewhere indicating that that was done.

I'm not much of a do-it-yourselfer anymore. Any guesses as to what it might cost to have EGR ports cleaned and the EGR valve checked?

Thanks.
