Idle Fixed but Engine Light Flickers

["Michael Theuri" <mikesoft@europa1.conwaycorp.net>]

I replaced the ISV hoses on my 88 80Q. Changed the 
plastic connector that forms a three way joint with the 
hose running from the back of the engine to the ISV
and also replaced the tiny hose that takes air to the 
injectors to provide a spray pattern. However my 
check engine light still flickers occasionally like it did
when the idle flunctuated though not as often. Does
any one have any idea why this might be the case. Most
of the time if will flicker on/off then go off for a while 
perhaps even for the rest of the day. Thanks in advance
and also to all who helped me diagnose and had access 
to our beloved album which I am now experiencing the 
importance of having.
