5KTQ fault codes question

[MHLIGGINS@aol.com]

	Earlier today I posted that I'd gotten a 2222 code during a "no 
start" condition. After looking frantically for the differential pressure 
regulator I posted a note to the list. Got the info that there is no such 
animal on the '87s.
	I did later start the engine and got the 2221 code, referring to a 
vacuum leak to the ECU. Put a vacuum pump on the inbound hose and it would 
not hold vacuum. Is it supposed to? If not, how in the world am I supposed to 
find the leak?
	Bentley was REAL helpful. "Fix vacuum leak." Or something equally 
enlightening. I'm about to go to Scott Mockry's page to look for test info, 
but I don't recall seeing any during earlier visits. Any other info 
appreciated.

	Later.
