This post is starting to resemble a jigsaw puzzle. If the code 21 keeps coming up, the ECM is going to switch into limp mode when the jumper is pulled. It's (the ECT) not getting hot enough. That would explain the 42 & 92 as well. The ECT needs to accurately reflect the engines temp. Did you thoroughly warm up the engine before running the KOER test?
