Can anyone tell me what might be the problem why this engine will not idle when in gear?
I have changed the IAC motor and the EGR as well as checked the timing which is advanced 2 degrees
Any more ideas?

have you checked for vacuum leaks?

No But what would be the best way to check for vacuum leaks ?

whell, what I do is look over everything very slowly and carefully near the carb/brake booster area. Then, if you don't see any damaged or disconnected vacuum lines, start the engine up and listen as best you can in this area for a hiss sound, and if you here one, feel around for it. I wish I knew a more scientific way to check for them, but I don't.
