Which engine? 9 codes? Clear your codes out and then see which ones come back. Write them down and post them.
If you have a misfire on #1, you need to figure out why it is missing. Does it have spark, fuel injector pulse, good compression?
Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.
