Fuel consumption problem
Hi I have a huge problem at hand. I own a 1.3 Bantam 2008 model. I use to ged 13km to a litre of petrol. Lately I have been getting 5km to a litre. I have changed and re-gaped the plugs properly, I have changed the air filter as well as the fuel rail conected to the injectors. (This was what my dealer suggested) none of this worked. I have very bad carbon emissions from my exhaust (which was checked by an expert and is fine) the vehicle also does not use oil and the coil wire's are also fine. Can anybody please give me advise?
try replaceing the fuel filter,clean egr,clean IAC.with carb cleaner.
This has been done as well. The problem is that all the fuel passing through the line does not get ignited if that makes sense.
Yea it makes sence,you stated you replaced the fuel rail,did you replace the injectors,if one is bad it will drip into the cylender and not ignite,I would have them checked,if you can do this test yourself,do this pull all injectors leave everything hooked up,put a piece of cardboard in front of injectors,have a friend or someone turn on keyswitch,see how the fuel spray hits the cardboard,they should all spray at the same time with same amount of spray,if 1 or 2 is a lesser spray pattern,they bad,replace do again,if spray is equal to the rest,you found the problem.
I had a similar problem on a customers car, it turned out to be a faulty water temp sensor and cold start actuator by the throttle body, first we replaced the temp sensor wich improved the situation later we replaced the throttle actuator and that solved it. We later added a unichip Q-type and that improved the fuel consumption even further. Hope this helps
I have a ford bantam 2008 160i its heavy on petrol. please help me sort out problem
I also have a problem with a Mazda 2.2 bakkie it very,very heavy on petrol pliz help
On these Bantams, check the fuel return pipe for damage. This will cause extra pressure at the injectors. The problem could also be the Engine Coolant Temp Sensor or wiring. Does the cooling fan stay on when the engine is cold ? It could be a software problem in the PCM. Only one person can sort the software problem out. Phone 0820606425 in South Africa
Regarding the Mazda 2.2 12 Valve petrol engined bakkie, Check that the vehicle's automatic choke is connected correctly. It this condition is happening in the winter time, it could be the chill factor of the cold weather is causing the choke to close when driving. In this case the intake air cleaner nozzle of the cyclonic air filter should be loosened and twisted so that the nozzle faces the exhaust manifold instead of behind the head lamp.
