Does the car have a symptom you need to remedy?

No real symptoms-runs fine has plenty of power. (The SRS being flagged is a little disconcerting). I’m trying to get the gas mileage up from 22-24 to around 28. It has new valve seals, plug wires, and new plugs, the diaphragm for the EGR leaks and it was disconnected and the vacuum line was plugged, the shift from first to second is a little harsh.
