Suzuki Vitara Excessive Fuel Comsumption Help required urgent!!

Help

My 95 Vitara 1.6EFI has developed extremely high fuel consumption although
the car is still running well. It is getting around the 200klms per tank on
a country run - at around 111kph.

Unfortunately we are temporarily in a remote country town and the dealer
here cannot look at it for many moons - we need to leave in a couple of
days. Advice please.

Dunno, could be a lot of things I suppose. Find someone sensitive to
the smell of petrol, and go for a ride with them. If they can smell
petrol around the car after you stop, I'd be checking fuel tank and
lines for leaks.

Otherwise, check air filter, stuck A/C, rolling resistance of car.

Check your air filter for locust bodies - they can clog up the filter PDQ

Any indigenous type folk following you the last few days? Are you sure it's
being consumed by the car, and not by people?

Someone I know suddenly had lousy fuel economy with their Nissan Skyline.
It turned out that the fuel hoses from the tank had perished; and every
time they accelerated, most of the petrol in the line ended up on the road.

Took us about $2 worth of rubber hose and 20 minutes to fix.

Grab that funny wee stick inbetween the seats, press the button at the end
while you lift and then release to the bottom. This may save you a bit of
fuel and a lot of wear and tear!

<Sarcastic bastard writer steps away.....>

Id check the airfilter first as if yourve been driving around the country
side for a while thats probably clogged, and then tyre pressures, stuck on
A/C compressor, debris stuck in grill etc etc ect.........

Take a look at the plugs, check the mixture is not being enriched. Possible to
have a leaky injector, or a malfunctioning or incorrect O2 sensor. Possibility
of the pressure regulator keeping the pressure too high.

Binding brakes? Low air pressure on the tyres? Carrying heavy loads?

Another thought - Have you been using AVGAS in the communities? In those buses,
the catalyst is easily poisoned and becomes obstructive, and may also collapse.
The catalyst can also collapse occasionally with stern off road usage.

And because my news server was down last week, I've missed some
of the replies already posted and probably your departure date.

How many kms has the car done? (somebody else may chip in with a
reply here as I can't see all the responses and it may have already been
asked) If more than 100,000km, I would start by looking at the timing
belt/crankshaft pulley area. If the belt has been changed and the front
crank pulley bolt loosened (unnecessarily, unless front crank seal was being
replaced) there exists the possibility that it wasn't tightened properly and
has now come loose and the front crank timing belt pulley is now flogging
out the keyway on the crankshaft. Uncommon, but not unheard of.
Getting the timing checked is the starting point here.

The cat converter may have partially melted (very uncommon, and the
cause of the initial lean-out would still have to be found) Limp-home mode
after oxygen sensor failure is LEAN. Is the vehicle's "check engine" light
on or has it been on?

Oh well, that's for a start.

Oh, another thing, "remote dealers" DON'T specialise in Suzukis!
More info on the vehicle would be appreciated.
