Too much Fuel consumption solution

Nissan AD suddenly consuming almost double its usual fuel consumption. After noticing the problem, I changed sparkplugs. The same issue persists. Help a villager.

[SIZE=5]I would advise uwache kuchelewa kazini, uongezee bidii kazini… ndio uongezewe mshahara uwache ku notice vitu kama bei ya fuel. [/SIZE]

[SIZE=5]Hizi tabia wachia akina @Sokwe mtu watu wa ractis. Anataka ractis imtoe SQ yake huko Rongai hadi Westlands kwa mhindi. Kisha anapea Ractis kshs. 250 of adulterated fuel ati hio thao iko kwa wallet ni ya malaya jioni.:rolleyes:[/SIZE]

[SIZE=5]Hio nugu @Sokwe mtu inashinda ikisumbua traffic police hapo Uhuru highway ati wamsaidia kuondoa ractis kwa barabara juu haina ngata na imefunga lane. :rolleyes:[/SIZE]

In the morning, does it have a hard start?

No. It just suddenly started consuming fuel. No hard starts

your MAF. could be failing, also your oxygen sensor could be clogged with carbonates,

Is your car producing much smoke than usual, especially black and lose or engine power, or have you noticed the change of smell in the exhaust fume.
If you’re experiencing the first scenario, your piston rings maybe be worn out, and you are losing compression, and oil is also finding it’s way into combustion chamber.
The second scenario, is where your car needs proper tuning up, so as to burn fuel efficiently.

Then your nozzle is not the culprit. Check mass air flow and oxygen sensors. However before changing these, have the odb guys check for error codes

:D:D

Jaribu kureplace air filter. Dirty airfilter can cause high consumption

The air filter is new

I will check MAF and oxygen sensors

Haina smoke.

I imagine diagnostics would pick MAF malfunctions? Ni expensive kufanya?

Its mostly about trial and error

:D:D

in some cars the diagnosis will register when the MAF has failed completely. but a dirty one will just be sending the wrong info about the oxygen going in to the car to the computer . cleaning with the cleaning agents sometimes helps. though not always.

UPDATE: O2 SENSOR WAS FAULTY.

Iko poa sasa?

Iko perfect kabisa. Ata fuel ni kunusa tu.
