93 Century Code 26 problem ...Help!

Pulled a Code 26 on my 1993 Century. I now know what the code represents and what the quad driver circuit is but I don't know what components could be bad or if it is just the ECM.

The symptoms: Has been stalling on me intermittantly and the idle is rough at times. The car has 86k miles and is great otherwise.

Any help would be appreciated.
