    Default Toyota Corolla 2003 gulps petrol, have tried everything

    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.

    Good suggestions. Before doing any sort of work, correct diagnosis is very important.

    I asked the guy who does diagnostics at Toyota Islamabad Motors today and he said he himself had an auto 2003 Corolla (SE Saloon) which gave low fuel economy, and that he sold it because of it. Also said the model doesnt have oxygen sensors. Its a tricky case really as the car is otherwise solid and has a much better drive than these newer, lighter models.

    Pay a visit to nazir autos and get your car's injectors cleaned ultrasonically. It will resolve the problem.

    Yes +1 from my side Nazir Autos in G-8 is one of the best places out there. My eagle eye civic was a fuel guzzler i got it tuned from them the average drastically improved along with the performance.

    Ask any question on this vehicle 02-08 corolla, I will help you out. If warning light is not on then OBD test will not give you any lead.

    They want you to replace the fuel injectors, here better solution is that get it cleaned manually and further if possible then do an ultrasonic cleaning.

    Your basic problem is clogged injectors as I guess that you never got them cleaned since year 03. Further, if possible then get the tappet settings verified, I know it automatically adjusts its self but get that verified if it’s still within tolerance or not.

    weak fuel pump has alot to do with poor fuel economy! Fuel pump failures almost always result in a drop in fuel pressure, which may affect fuel economy! if auto tranny fluid hasnt been changed that leads to poor gas mileage too!
    and if injectors were clogged the car would misfire! so its not an injector problem!

    talha yeh toh zara batana keh injectors manually kaisay saaf hote hein? u gng to say the typical ustaad answer by saying spray carb cleaner on it?
    and its not necessary that the engine check light has to come on for a person to run a odb2 scanner! sometimes the ecu stores codes but does not display them via check light! ur knowledge abt cars seems weak!
