Okay, I adjust the TPS is okay and I found out that I have timing light for reading rpm very low at 556 rpm. That book say must be 750 rpm with jumper terminals E1 and TE1 on the SST test connector. I adjust the stop level screw for read 755 rpm. So, that reason of rpm very low, that cause the engine stall with EGR on. Now, EGR work much better with engine idle but for awhile few minute again. It feel like again, the engine idle miss few second more then smooth, it like missing three times and then no missing, and few 5 second missing three time or less. It very wierd and no clue of where this come from. All I do everything check look fine and no engine light code at yet. My wife try tell me, "Maybe fuel filter need to change for now". I told her, " I got a test fuel gauge reading very good high pressure". Man, I don't understand all no clue.
