Hello!
I have a 2016 Honda Accord CR-V Touring AWD I4 38k-mi. After warming up the car, I plugged in a scan tool and looked at live data. Everything seems fine, except the short & long term fuel trim were both at -5%.
Car was bought used in 10/2021 @ 32k-mi. I change oil every 5k mi. New engine air filter. I cleaned the MAF. I also used a bottle of ATS 505CRF and used the whole tank up before scanning. I don't see or hear any air leaks. Could this potentially be just a dirty fuel injector and ill just need a injector cleaning?
Thanks!

Yes. How about your fuel filter too?
Haven't touched the fuel filter. But if it was a clogged filter, would it cause the trims to be more lean?
Is your gas mileage affected? If it isn’t, I wouldn’t really bother..
