If idle stabilizer is okay i'd check for vacuum leaks and dirty injectors. Run some techron through the gas system. I will check my manuals tomorrow and if they have a trouble shooting guide i'll post it tomorrow.

Hey, i'm back. From the shop manual. For irregular idleing check:
full load contact,engnine temperatue sensor ll, air mass sensor, idle speed control, fuel pressure, intake system leaks, fuel tank venting, injectors. i hope this helps.
