Not exactly a newbie but never posted before. Here is my problem. My 98 2.5 had an outright stall with no warning at highway speed (about 75mph). Still unable to start, engine barely turns over any thoughts on cause and repair cost would certainly be appreciated.

 

Timing belt?

 

hey, I have a 95 mazda Millenia, and the same problem was happening to me... not only in the highway, but city as well...I had my EGR boost Valve, its kind of a square shape and has a little rubber hose that connects to it...it should be easy to find, never had a problem since i changed it..

 

Sounds like Timing Belt to me too
