I have a 2001 Ford Escape (110,000 Miles) V6....and I've just started having problems with the engine dying when I start it up..... Just last week while I was driving the RPM drop to zero and the engine died.... I've recently had the lower intake head gaskets & egr valve changed because I had a vaccum leak.... Sometimes out of no where the engine will die unless I give it some gas.... And the RPM drops to zero.....Does anybody know what could be causing this issue?
