Hope you didn't forget to replace the oil oring on the distributor too

 

Has anyone GS ever shut off when u come to a complete stop "red light"?

 

Yea spark plugs are a b****, my buddies evo used to have all kinds of problems with them.

 

I had this same problem, tried everything and it turned out it was the Idle Control Valve. Took it out and gave it a good clean which fixed it a little but eventually replaced with a new 1 and now car runs better than ever.
