Hi guys, my Toyota Corolla 2003 EFI Automatic is consuming too much petrol these days (6 km/litre, no CNG installed). I have had the spark plugs replaced, engine tuned, fuerl filter replaced, oil changed at regular intervals, tire pressure is OK but nothing seems to work. Online some people recommend to replace the MAF sensor (which i clean regularly) and the oxygen sensors, and the dealership suggests getting fuel injectors replaced as well. All these repairs cost well above Rs.80,000 which isnt worth it. I am hoping to get parts from eBay or online.
I am open to suggestions and leads as to where I can get these parts at reasonable prices in Islamabad/Lahore.
