Waterpump could be leaking onto the opti.

 

Could be a burnt plug wire as well.I'll stop now.

 

My experience with my 93.....don't expect much from the computer. It kind of sounds like my problem where it's running rich and is missing. Check my posts for ideas from what others are sying.

 

Did you short the ALDL pins the corret way?

Running rich is often the result of:
-excessive misfires
-exhaust leaks before the O2 sensors
-faulty O2 sensors
