Ford Mustang runs rough, no power (code P0300). EASY FIX. 2005-2014, V6

2010 Mustang running REALLY rough, but intermittently, and has almost no power. Code P0300 set ("multiple random misfires detected"). Took less than 15 minutes to replace the ignition coil which solved the problem.

so i haven't had it read with a code reader yet, but if it has a rough idle but only when the A/c is on what would u say this would be?

Hard to know but the AC system doesn't directly tie into ignition or anything like that. Instead, turning on the AC puts a strain on the engine, so I'm thinking your AC just makes your problem show up, it's not actually causing it. In other words, fixing the AC system isn't the issue; it's likely related to needing a tune-up (spark plugs, fuel filter, etc.).
