Two thoughts:
Float is sinking,
thermal vacuum switch for the charcoal canister is saturated.
check the lines going to the canister for fuel droplets, if wet change the
switch.
Used to stick open (or was it closed?), and then the canister would
saturate, and engien would be way rich
Grumpy

| Hi guys,
| My wife's 88 Caprice wagon (carbed 'Y' Olds motor with a 8330
| ECU running a ADAY bin) is showing an intermittent SES light.  Within
| a couple minutes of starting it'll come on,  then be on for a couple of
minutes,
| then go off again for a couple of minutes,  repeating as long as the car's
| running.  It's running real rich,  but doesn't set any trouble codes.
P.O.
| said they'd taken it to mechanics who swapped ECUs a couple of times and
| were stumped by it.  They concluded it was an intermittent break somewhere
| in the harness and told the P.O. it'd cost more than the car is worth to
fix.
| I just got Andrew's ALDL interface working and I intend to watch the ALDL
| stream and see if something changes drastically when the SES changes.  I
| haven't found any references to this particular ECU on the web.  Is this a
160
| baud aldl or 8192 baud?  The only software that I've found for 160 baud is
| Peter's ALDL.exe  which looks like it may do the trick for me,  but is
there
| any other 160 baud compatible software out there I should be looking at?
| Also,  while I'm asking about this car,  will an intake from a SBC fit
this Olds
| motor?  If so which ones? It's pathetically anemic,  and crying for an
upgrade.
| Any comments or suggestions would be appreciated.
| Thanks,
| Bill
