First, it is real easy for me to spend your money, and real difficult to definitively troubleshoot through the internet, so question away. I don't think anyone will be offended, and I know that I'm not. i will feel bad if you replace the ECM and it doesn't fix the problem, but not bad enough to pay for it!Owch. That will hurt a bit more then I was hoping for.
Just wanted to double check a couple of things.. This is an intermittent problem. After this happened a couple of times, I drove likely 75 KM with no issues, and now its back to being a common thing. Last I tested, it wouldn't idle for even 3-4 min. So based on the fact it is intermittent, including all the additional information previously mentioned, how sure are we this is the ECM? Not trying to question anyone ability, I just don't wanna spend what will amount to about $750 after all is said and done on like a 50% chance kinda thing.
Or maybe I should ask. If it was YOUR sky. what would you do?
There are seven codes associated with the knock sensor. i should have posted this earlier, but i got lazy.
If you had other codes, there are other things to check, but i still read that this is the ECM.
You could do some of the other testing if you have a DMM with the correct functions, and that would rule out the knock sensor and wiring. You could also invest $15 or so to replace the sensor.
Either of those is quite reasonable to do, and you may find a different problem, but unless there is something going on that you either can't see or haven't told us, my money's on the ECM.
