It's a good start getting the O2 hooked up, now your next issues; Code 32 - EGR will come on after the engine is warm and you're cruising over 45MPH, that's when the ECM tells the EGR to open so, it seems your EGR valve (circled in blue) either is stuck/dirty, or your vacuum hoses aren't hooked up right/connected. Code 43 - ESC can be a couple things, your ESC (Elictronic Spark Control) module (circled in red) that the knock sensor is wired to isn't getting feed back from the KC (the ECM checks periodically) or the module is bad. Another problem could be your ICM (Ignition Control Module) in the distributor is bad, this was my problem recently. This is assuming all of your wires are connected properly including grounds! Both EGR and ESC are in the same wiring harness on the passenger side of the throttle body. When you shut off the engine the CES light will go off but the Malf codes will stay stored until you restart a certain amount of times - usually ~30 - 40 times or disconnect the battery.
