Customer has a 90 seville with the 4.5. the car is dying at red lights and while slowing down from highway speed. there are no ecm codes in the computer. I did notice that the spark degree was changing quite rapidly right before it would die.

Dirty throttle body? Bad or dirty EGR valve or solenoid?
