And how often do these go bad? My computer seems to be making bad decisions with the info its being given EX: when the o2 sensor voltage is ploted it shows that it is running lean and the computer compensates for that by adjusting the fuel trim to make the car run even leaner. im boggled is there something im missing

also what ecms are interchangable for my car. I have a 92 3.1 rs.

Lots of cars run this ECM: 1227730, or the 16198262. Look for '90-'92 V6 f-body's, '86-'94 Celebrity, Corsica, Beretta and others.

May want to double check the fuel trims. A lean engine being given more fuel will have a BLM > 128.
