my 93 MX6 stalled while driving
 

I was driving on a freeway and my car suddenly slowed down and stalled. When the tow truck came, I tried starting again and did. But as soon as I drove, it died again. After being towed home, car parked for an hour then I tried starting and it did and was able to drive into the garage after it cooled down. I replaced my distributor 3 years ago. After the 2nd year I kept seeing my check ingine light on at least 2-3 times a day. I'm guessing the ignition coil (is it built-in the distributor) ...Appreciate any feedback, Thanks.

Fixed the problem. Replaced my distributor but still getting code 16 and 28 (egr valve and solenoid valve egr vacuum). Any thoughts?

EGR could have carbon build up in it, resulting in less than optimum performance. The same thing has come up on my sister-in-law's car, escort. Mechanic said this can happen, instead of the valve going bad, it's just clogged, or partially clogged.
The solenoid valve could be hampered by the same thing. I don't know for sure though.
I'd try cleaning out the EGR valve and see if there's any improvement.

My 1990 mx5 died like that and it ended up being the tach. Took two week for the garage to find the problem. The tach shorted out.
