Sender Values..????
I borrowed a scanner for my 1992 305cu TPI.This is a complete rebuild.Running stock cam and heads. I am running speed density.No MAS. I have written down sender values open loop and closed loop that I scanned today. My problem is hard starting and when it starts it runs really rich. Is there a list of values for the sensors? Need O2(mV) , IAC Position, Learned IAC, MAP (kPa), MAP(V),Coolant(C*), MAT(C*),and anything you think will be helpful.

The sender for the ECM is ok. I had a fuel problem. Fuel pressure was to low. Fixed it. Low fuel pressure will cause all kinds of ugly things to happen. Car in almost ready to go on the road. Thanks
