Hey everyone, so I failed emissions, like apparently a lot of e30's do according to my searches :D. The car has 186k on it, and the PO had new plugs (Autolites, but probably gonna change to ZGR5A's), air filter and fuel pump put in. I was way over on my HC's under load, and a hair under the limit at idle, here's the read out:

I tried the stomp test as a prelim to possibly point me in the right direction, except it came back 1444, or no errors! I'm definitely not complaining, but does that definitively rule out things like the o2 sensor and possible leaks? I'm new to this stomp test thing as I never had to mess with it on my e36 and my e28 didn't have such wizardry.
I'm about to order new plug wires, plugs, distributor cap and rotor since like I said above the plugs are Autolites and the plug wires look ancient. I'm also thinking of replacing the thermostat and coolant temp sensor as a preventative measure (might as well since I have to do tb/wp, adjust valves, gaskets, etc.).
So what do you guys think? I can't find any threads of people failing emissions without codes being thrown so I'm not sure what to look at replacing other than the ignition stuff and possibly the cat if the new ignition set up doesn't resolve the issue. Let me know if I missed something in my searches as I'm trying to soak all of this new system in. Your guidance is much appreciated!
