					Boging is normally a lean condition.  Look at anything that allows too little fuel or too much air.  Dirty injectors / clogged fuel filter / low pressure / volume.  Check fuel pressure with and without vacuum hose connected. Verify DME coolant temp sensor (blue) with DVOM.  Look for cracks in the boot from AFM to TB.  Intake gaskets leak?
Have a local buddy with know good AFM you could try?
DO you have a newer M42 with knock control?
Main relay original.  They can go bad.
Wouldn't hurt to clean engine grounds and the positive junction block to make sure you are getting proper voltage.  
Good luck.
