Message OK, I did my searching and didn't find anything that was specific to my particular problem, but if I've overlooked, then slap me around and point me to the right place, please...

'94 Z32 n/a, 2+2 automatic - 199k miles
- Intermittent engine light, stays on for a week or two, then goes out
- Starts/runs fine
- When engine light is on, obd-II codes say vacuum leak
- After running 20-30 mins, car stalls at idle... BUT immediately restarting car fixes low idle problem for another 10-15 mins
- Same problems whether engine light is on or off

Attempts to fix:
- Could not find vacuum leak when engine light is on
- Replaced EGR
- Replaced plugs/wires (overdue)
- Cleaned MAFs

Disclaimer: I am not a mechanic. All the above suggested and performed by ASE cert'ed mechanic friend, well regarded, but not familiar with Z's (if that's relevant). I have since moved away from mechanic friend and am on my own. I'm a quick study, but need layman's terms/explanations for what I should try next.

Can anyone help?
