Guys, what could be wrong with my 1999 Toyota Camry. Full tank of N7,000 doest last up to 1 week. Its a Tokumbo bought in January 2012 and has been serviced only once.

My Route: Festac to Victoria Island

Bros. In d servicing, what and what were changed or was it d normal Oil and Oil filter Change?

The culprits for unecessary fuel consumptions are, 1) Very dirty fuel filter. 2) Weak fuel pump .3) Bad Spark plugs and wires. Try and check those since itz a Tokunbo car cos U dont know when d last owner changd them. My 20cent.

normal change of oil

I'll look into ur suggestions. Thanks

Bros. How is ur car? Does it still guzzle Fuel like a camel in Sahara desert?

^^^^^^

None of your suggestions has anything to do with a car running very thirsty or that degree of richness. Yes, they could cause rich mixture, but not to that degree of the Op car.

So what should he do?

The following below, if faulty, will make an EFI engine run very rich/overfuel:

1. AFM (Air Flow Meter)
2. MAF (Mass Air Flow) sensor
3. MAP (Manifold Absolute Pressure) sensor
4. IAT (Inlet Air Temp) sensor/thermistor
5. CTS (Coolant Temperature Sensor)
6. FPR (Fuel Pressure Regulator)
7. O2 (Oxygen) sensor
8. Vacuum Leak
9. Clogged/bent fuel return line
10. Etc.

Once any of the components above starts malfunctioning or failed, your car will start running very very rich or thirsty. Fastest way of diagnosing this issue is by scanning the car. Though, I can manually troubleshoot or test the components myself, without the scanning & detect the culprit. But if you cant do it, take it for scanning.

Yes. Those where days when cars were damn reliable. Very soon, cars will start suffering from virus infections. Is a matter of time. The thing is: the newer a car, the less reliable; the newer a car, the more headache to fix when something goes wrong.

I replaced the fuel filter, yet no IMPROVEMENT in fuel consumption. The engine is very sound cos I see water droplet from the exhaust when I start the engine in the morning. Also noticed heavy combustion form the Exhaust pipe but no black smoke this time.
I remember spending N2000 on Fuel in one day. My route? Festac to Victoria Island.

Guys your suggestion is highly needed.Thanks

Your car should have an on - board diagnostic point (OBD), have it scanned !!!

Remove the plugs and check if the white part is now brown in colour. If it is, change it. Buy original toyota denso plugs. Check d air flow meter for dust and clean it with a soft cloth or very soft brush. Make sure its not torn.

Check ur plug wires.

gas will always burn in any car
just like what ikenna did say
all those apprameters must be
working in proportion, it also depends on how
your car is driven ie driving smoothly burns
lesser fuel than when its been done like a car race show
allowing transmission go smoothly is the key to burning less fuel

my 99 camry also is consuming much gas. I have carried out an OBD test and the results are:P0401,P0446. Can someone explains in details to a layman or roadside mechanic how to tackle this problem effectively.

At last the excessive fuel consumption is all over. The 'Culprit' are missing radiator thermostart, faulty air flow sensor, faulty EGR sensor and faulty oxygen sensor

After replacing these items, my fuel consumption improved TREMENDOUSLY. Now Full tank of fuel would last the whole week.

Congrats man! Good to hear your car issues have been sorted out. This your thread will also enlighten more to people the implication of removing the cooling system thermostat.

Dear appleton,
your reference is much appreciated!

It was a pleasure serving you! Do contact us for any further questions or queries you may have.

Guys please how do I know if my cars thermostat is intact and working?

Temperature gauge should read approxoimately half within 4-7 minutes from a cold start, without AC on.After this period the upper radiator hose should be hot to the touch. If the hose remains luke warm this indicates thermostat is either not present (removed), or is opening too early relative to the specific temperature stamped on it's body. This does not allow the engine to reach it's operating temperature and the temp.gauge will read low. Engine cooling (water flow through engine cooling jackets) takes place once the the thermostat opens.

Hope this helps!

@IKENNA: please I'd need your expert and thorough opinion on the dangers of knocking off the Thermostat of a Toyota Camry 2000 Model.

What could possibly go wrong in the long run and does it make the car consume far more gasoline?

Your candid response please.

Yes, it will make your Camry very thirsty, among other things you wont find funny.

Number One, advice if you want to save your fuel don't drive your car.
Festac to VI what typical part of the day, do you drove this route, been on so.called go slow not traffic jam rake havoc on car fuel content

Please house, i can see that EGR on my camry oh!!! And the fuel consumption is killing me.
Seems the previous owner had it removed. Bikonu help me... What can i do.. Its iv4 1997 camry. quote author=Ikenna351 post=11485768]
