Light misfire but no codes??

[Pujols5]

I’ve got a 2019 Equinox premier front wheel drive with the 1.5 liter with 46,000 miles. I bought it with light front end damage and had it repaired. For the last 14,000 miles it’s had a light misfire under very light throttle. If I hold the gas pedal while driving 1800 to 1900 rpm it wants to cut out and have a light stumble/misfire. It only does it at that exact point and it’s pretty light but will consistently do it. It never throws a code or check engine light. It will also lightly do it when at an idle. If you put your hand over the exhaust pipe it will occasionally flutter but inconsistently. Does anyone have any ideas??

Are you sure the check engine light works? If it's a true cylinder misfire, you are definitely going to have a flashing CEL and codes present. Any other symptoms like poor fuel economy, nasty looking engine oil? This is a weird one.
