[alpha17]

My recently bought corolla 121 gives me a very low fuel economy.it's details are

-yom 2000

-1500cc

-automatic trans

-g grade JDM

i posted a topic before and manage to do some repairs.but the fuel consumption is very high.it gives me only 7.9kmpl in the city.outstation nearly 12kmpl.i've manage 2 do these repairs,

-changed the automatic transmission oil using toyota genuine oil

-changed engine oil(castrol)

-changed the fuel filter (vic)

-serviced recently

every gear changes between 2.5-2.7rpm.and also some times a loud "kiri kiri" noise comes when i accelerate the car.i think its the fan belt maybe.

so plz give you suggestments soon and they'll be vry much valued for me.

Two cents: do what they call a full efi tuneup.

1. Clean throttle body

2. Clean intake manifold

3. Check for any oil leaks thru distributor or other hard to reach places

4. Clean injectors

5. Check fuel filter/rail

What's your mileage? Maybe our belts are slipping too.

There's a considerable amount of carbon buildup overtime the inflow parts. Messes up performance. Get the above checked

Does the yom 2002 and above 121's do better on fuel than the old 2000-2001 models?

I dont know abt 121 fuel consumption, but if you think its high, do things that Komi have said first, If the problem persists, check your O2 sensor (lambda sensor),

read more abt lambda sensors, read the first post there.

kiri kiri sound must be coming from the belts, get it checked.
