Hi guys, just signed up to this forum, on a friend's recommended.
anyway I have a Hyundai Accent 1.3 GSI, 2001.
Its been a nice drive so far but recently I have noticed that the petrol just runs out so quick.
Any suggestions guys??
|
fix the leak?
give it a service?
f.o.g.........foot off gas drive sedately
engine worn?
someones nicking your fuel ( a fuel fairy maybe)
dunno :-(

If isn't leaks (you'd probably smell petrol in or out of the car if it was)..
Then either the engine is working harder than it should (but then the car would feel like it was labouring more on hills more than it should/used to ) OR if it feels OK, then perhaps an injector / Computer fault/ sensor fault.
An emissions test maybe an idea to make sure it isn't all going out the exhaust pipe (look at CO and HC readings). Also look at the what emissions are like on idle. But if you take to a garage to do this, tell them why so they also try and trace any faults.

Have you looked at the air filter? Are the plugs the ones the car came out of the factory with? Anything obvious like that?
|
Air Filter is clean YES. I must confess I haven't changed the plugs for 2 years but then I don't drive that much anyway. I have only done 9K miles in 2 years.
Should the plugs be replaced? and How do you know when to change the plugs??

thanks for the quick reply.
I am a good driver and look after my car, so I am definitely not putting my foot down on the accelerator.
I just got my MOT 2 weeks ago, and the emissions were perfectly fine. However having said that, I can smell the petrol, especially in the mornings and it is a really heavy petrol smell.
Does that indicate something significant?
|
Sounds like a leak somewhere. Trace and fix (follow your nose!).
Petrol smells can be misleading. The filler-cap breather tupe is defective on my car and a smell of petrol is sometimes apparent although there is no substantial leak, just fumes through a small tube outside at the rear of the car. Some trick of aerodynamics.
|
|
sorry should have made myself clear, I meant I can smell the petrol through the exhaust at the back, but the smell is quite strong.
|
|
If you don't know how old the plugs were when you got the car they may well need changing. They are only good for about 20,000 miles I believe. But they may not be the reason for the petrol smell. All cars run rich when they are cold but I don't think modern ones should smell of petrol!

Any change in warmup time,and is temp guage working ok?
|
yep warm up time is still normal and the temp guage is working ok.
As for the plugs, I have been asked to get Bosch super 4 plugs.

Don't waste your money - get standard NGK plugs, £12 a set from Halfords (maybe cheaper from an independant motor factor). Far better than Super-4s too.
|
so could anyone help with the petrol smell from my exhaust??
I am really stuck and don't know what to do. I am worried that if i take it to a mechanic I might get charged too much and since I am a student, I am trying to save every penny I can.
THANKS FOR THE SPARK PLUG ADVICE. Cheers

Sounds like possibly the air temp sensor gone wrong causing it to overfuel,should be on inlet manifold,not certain of this car,is it the same as the earlier engines ie 12 valve
|
yes it is a 12value.
I am just trying to pin point the problem. Some people have mentioned it could be the FUEL Filter, others say it could be some Land or Lam Sensor that measures the air coming in or something.
does this air temp go wrong often? because my car has only done like 49K miles.

Hello.
A friend who I used to work with has a Volvo S70 and it had terrible fuel consumption.
The Garage could not solve it.
It had new Spark plugs,Leads,Air filter,They even checked to see if the injectors were leaky etc.
A few months later He had the battery replaced as it struggled to start.
Almost straight away he noticed the car was less lumpy etc and used much less fuel.
From what He told me I think that because the battery was removed the ecu had to reset and lost all its previous settings (bad driving styles etc) and started fresh.
When it came to the mot the tester commented that the emissions were much much lower.
Hope any of my thoughts help.

What is your actual fuel consumption then? Maybe your car has a small tank so it just seems like you need to fill up more often? Or maybe you have unrealistic expectations or are comparing it to another car that was better on fuel?
If not, a good service wouldn't do any harm and also look to things like sticking brakes! Cars do run richer when first started. You would be able to see a leak I'm sure if you started the car and looked under the bonnet and underneath etc.
|
Battery replacement sounds interesting because a couple of days ago my battery flattened out for no reason. I did not leave anything turned on but still it went flat.
By the way isn't there a way to RESET ECU without changing the battery?
As I said its a 1.3 liter 5 door hatchback. It used to do 250 miles in a full tank of 35 liters but before that it used to do even more and now I would just about do 200 miles. So it has significantly fell.
As far as my driving goes, I am a good driver and look after it but I do admit driving a bit rough couple of weeks ago when I was in a rush. Could that have affected it?
Also do you reckon it is worth changing the Fuel filter?
|
If it is overfueling, I am surprised the MOT emission test didn't pick this up (unless it only happens across a narrow rev. range or fault was not there a few weeks ago) Surely the HC reading should pick this up?
35 litres in 200 miles is c. 26mpg, which is low for a 1.3 litre unless you are in stop / start
traffic all the time and heavy footed.
Sometimes disconnecting battery can reset ECU - but as not an expert on ECUs, hopefully others can give better advice - You may loose radio codes etc, so will need these.
Otherwise I thought reseting ECU involved plugging in some sort of Computer into the diagnostic outlet of the ECU.
In any event, the battery condition should be checked.
When cold you should smell a bit of petrol in the exhaust, which should go once the engine is up to temp. If it is a leak the smell would be apparent just after you parked it after driving it.

Get an MOT tester to run an emissions check on it - they check CO, HCs, and Lambda readings, which on a modern car should be WELL within limits (even my 2000 Almera barely emits 10% of the prescribed amounts). Lambda reading should be almost spot-on 1.000. A bit of heavy-footed driving won't cause any harm to the car. Change air & fuel filters, and the plugs - it'll only cost you about £25 to DIY, and will immediately eliminate these, as well as treating the car to a half-service!

you guys probably do remember me from two weeks ago when I asked for help for my Hyundai drinking petrol.
well, I am posting this to say a big THANK YOU to all who tried to help and replied to my post. You have all been a great help and as advised I changed the Spark plugs and noticed a difference right away. The car felt lighter and so far is driving better. I still gotta check to confirm that the mpg has increased, I will keep you posted.
Speak to you soon

Have you checked your tyre pressures lately?
