I apologize if you already saw this, tried posting it earlier but doesn't seem to have shown up.
Our 1993 245 has been starting then stalling after 30-60 seconds. Have checked numerous possible causes; AMM (resistance test), idle air control, throttle switch, pressure regulator. Have also changed plugs, wires, cap and rotor.
It finally ran today, don't know why. I'm still getting check engine light though and now I'm getting diagnostic codes 1-1-3 and 1-2-1. Before today I was just getting a normal 1-1-1.
I lost my job 3 weeks ago and things are tight or I would have taken it to a shop by now, so if anyone has any ideas please let me know. Does the 121 code mean the AMM isn't sending info to the ECU?
