New craz misfire codes

So my 17 craz threw the 301 code today. I noticed it done it twice
Both times after I had both ballasts full in the rear and emptied them. Could they be pressing against that #1 plug wire causing more pressure then once drained release pressure and cause the #1 cyclinder misfire code? Just a guess, I do have the wakemakers 1140s upgrade bags and the reinforcements for the walls and they sell. Once I rest the batteries after the tanks were drained it would never come back, but it didn’t throw it while the tanks were full surfing and it didn’t seem to miss a beat? Engine sounded good when code was on, anyone with any insight or experience?
Thanks

Loose spark plug wires was the reason. Also while the dealer had it, he replaced some sensor for the exhaust.

Dan what exactly was it that caused this? Do you happen to know what sensor?
Thanks!
