P0300 persists
I've been using Dash Command to monitor the effects of the various upgrades/changes that I've made over time. I had misfire codes p0304 and po300 so I replaced the cap and rotor with AC Delco parts and while I did see the p0304 disappear, the p0300 persists. There seems to be a handful of misfie (10 or less) at various times on several cylinders. Is there a tolerance for misfires or will the code trip even if there's a single misfire detected? If I wasn't seeing them on the readout I wouldn't even notice them it runs so smooth.

0° ± 2° You can clear the code with Dash Command and see if it returns. Note that with Dash Command you have to buy their enhanced PIDs for your particular vehicle, in order to do cam sensor retard ($10 + $10 more for enhanced PIDs).

Either add the GM.ENGINE.CMP_RTRD PID (found in General Tab) to the Data Grid or make a Gauge to display it.
