Help! My 2020 WRX is showing really low AF learning 1 values. I’m not sure why, all the other values are staying relatively normal and this started out of no where a few days ago. I’m on a stage 1 91 octane tune +big SF. The only mod I’ve done was the Cobb big sf intake and it was about 8 months ago. I tried cleaning the filter and the MAF to get the numbers up but no luck. Anyone know how I can fix this?
