Update: I advanced the base timing from 0 degrees to 4 degrees (next notch on scale). I was getting a code 42 ECM problem of some sort and a 54 fuel relay voltage problem. Today on arriving at work I didnt generate any codes. So timing increase has fixed these somehow.
I am trying to connect my computer to the ALDL connectors using WinALDL. Having trouble with the data, not sure if this is an old 160 baud or newer 8192 baud ECM. I also dont know which transmission I have or if my ECM controls both engine and transmission. Need to find out how to tell.
