Sooo, yeah, more troubles for a change. My idle is still hunting after changing the engine, so it must be something from the old.
That's not really the problem tough it may be related so I mentioned it. Problem is I'm stuck on open loop I think. I failed the emissions test 2 times already, changed the catalyzer after the first time and went from 1.7% CO to 1.0% CO, max is 0.5% CO. Lambda value is 1.01. CA18DET btw. The second time I passed the acceleration test (between 2000 and 3000 rpms) but the idle test I could see the CO dancing from 0.01% to 1.9% pretty much randomly.
I tested the ECU in mode I and II, no blinking, light stays off (both). They are on with the ignition switch, but turn off when starting the engine and stays off no matter what.
I have changed the lambda and ECT sensor but still no blinking. I don't think it's the MAF, but I may try that next. But assuming the MAF is ok, what could be the cause of constant open loop?
And btw, what exactly is the difference between the preface and postface AAC assembly? A friend has one from the preface and it's visually identical, I could perhaps try that on see if it changes the idle behavior.
