well your codes seem to be from them being disconnected, no?

seems to be the case, i have extensions coming in later this week, so far the cars been driving great!

So I got the new cats in as well as the downstream O2 sensors, CEL is gone and there are no longer any trouble codes. However the emissions readiness s/DTC is showing that the Catalyst and EGR system are incomplete, before installing the cats only the catalyst was marked as incomplete. The upstream O2 sensors oscillate between 0.1 and 0.9 (sometimes staying high or low for a little bit), the downstream O2 sensors sit at 0.04 or lower sometimes drifting up slightly followed by going back down.


Any ideas for the Catalyst and EGR system being marked as incomplete? I'm thinking I just need to drive it more for the ECU to register things.
