Its the rear O2 that's cycling. I do have a 2 minute log I can post up if that helps? The 20 minute ones are to big to post up, unless there's somewhere better to post them to?

If it is the ECU stuck in SAS mode, how can I test to verify? Is there a fix for that? That makes sense to me, that it's not coming completely out of SAS mode, that it would ignore the fuel trims... But, isn't the ECM just a bunch of tables? If the ECM is ignoring the fuel correction tables, they're still there, are they not? Shouldn't evoscan still be able to look up and pull the values from the tables, even though the ECM is ignoring them?

I'll head back to the garage tonight, and make sure the connector is away from a frame ground, but I always put the plastic cap back on.

Yes, this is a 1G PnP from Jester.
