Troubleshoot Engine Codes - Toyota Yaris Forums

So it looks like the locking tab broke off my Ignition coil caused the multiple misfire. I am about to switch out the connector with another one from my old harness. I had my alternator tested also at Advance Autoparts. They said it tested good but when I took it for a "spirited" drive the volts at idle where 12.1-12.7 with AC on. When I turned on my headlights it dipped to 12.1v and almost stalled. Revved it to 2000rpm and it jumped up to 13.2v. Still have the P0010 after replacing the part. Is it possible the alternator is bad or bad ground?

How did they test the alternator? With the engine running you should see over 13V (typically 13.6V at the lowest while idling), and it really should not drop, even with the AC on.
