Step one: don't just dump the electronic system without finding the source of 
the problem.  It's usually less expensive and better to repair a existing 
system rather than building something from scratch.

Step two:  Place a dwell meter on the green single wire test connector.  It's 
located near the carb's blue connector( Shannon, did the 83 Olds still have 
them?  It's been quite a while since I've looked at one).  It should read ~ 
30 * at idle, I beleive the dwell meter should be set for the 6 cyl scale.   
0* dwell would indicate the ECM is forceing a rich mixture.

Step three:  Pull the hoses off of the purge valve. ( Black plastic, round 4 
to 5 hose valve located front and center of the engine)  If liquid fuel runs 
out, replace this valve.  These fail frequently causing super rich mixtures.  
 From what I recall, the valves were under $ 20.
