Too many cranks before start and fuel consumption
I apologise if this has been covered, did a quick search but would prefer to have a straight answer to my specific problem.
I've had my car for 6 months and when i just got it, it would crank once and start. Nowadays it's taking 3ish and sometimes even more, seems to be struggling to start. Would anyone be able to tell me what's going on?
And also my fuel consumption is now at 13-15L/100km even after replacing my broken thermostat. I thought changing it would let the car run at the right temp and fix the problem but it's still chewing hard. Now i've heard o2 sensors and fuel filters may be the culprit. Is there anything i can check myself without having to take the car to mechanics? Haven't got time and wallet getting real thin since i drive daily and tank only takes me 250km.
The car is 104xxx km, automatic, integra gsi. Heavy start-stop driving, giving it the occasional boot
Thanks for any help
