My problems started a few weeks ago. The engine was running very well except for a minor hot start issue. I had the injectors cleaned. Now the
engine hunts when first starting for about a minute. I assume it does this while the cold start injectors is active. Here is a video of it hunting and then suddenly stopping:

The idle once warmed up is rough. I've been trying to put a dwell meter and check the idle but no matter which way I adjust the screw the dwell reading does not change. Could the CO plug be bad? Here is a video after the engine has warmed up.

What do I need to fix?
