Help maine diagnose OBD2 reading, substance ratio dropped!
Background of my car:
Grand i10 Petrol - 72k Kms old
Service History:
Last twelvemonth clutch kit was changed and mileage was bully station the replacement and was easy astir 14 successful city.
Now 2 months backmost one got a wide work done and they added a worth adhd occupation of "combustion enclosure cleaning". Now aft this work mileage has fallen large clip to astir nether 10 successful city.
Post this driblet successful ratio one person changed each spark plugs to Iridium ones, cleaned the MAP sensor recently, cheque spark plug wires for resistance, throttle assemblage checked(it was already clean), utilized a Liqui moly injection cleaner and besides added a Liqui moly motor lipid friction reducer but mileage is inactive hardly 10 ( precise flimsy improvement). I person the Torque App and one person utilized it to cheque the pursuing information points:
1. Long word substance trim values - Has been nether 5%
2. Car seems to person a constrictive set O2 sensor and hence nary A/F ratio readings. Car goes to unfastened loop connected hard throttle.
3. O2 sensor 1 shows modular fluctuating readings which one deliberation is normal.
4. O2 sensor 2 shows precocious readings meaning motor is moving affluent which matches the substance ratio issue.
5. Coolant somesthesia sensor shows 90 wrong 10 minutes of thrust showing its moving ok.
5. No issues successful acceleration and car drives similar caller but this mileage drop.
What could the contented beryllium ? I consciousness the combustion enclosure cleanable has caused debris to deposit connected O2 sensors oregon the CAT causing atrocious values. Or tin it beryllium immoderate benignant of a substance leak somewhere?
