I'm confident that this is operator error.
I was all excited to put in my new ECMLink .... and the car that earlier today idled great now idles like crap.
My O2 never budges off of .04v, and my timing at idle is all over the place. I didn't drive it, this is all at idle. I have a wide band on the way, and not trying to tune it right now.
And I'm apparently not smart enough to figure out how to upload my log.
794rpm 15.2 degrees
843rpm 2.9 degrees
My O2 is relatively new. No CELs. With the stock chip, idles and drives really well.
Edit: O2 does read >.25v when throttle is blipped.
