I am thinking I may have got fuel that had dirt in it..

I made the mistake of fuelling up when the Petrol truck was there...

The Motor developed a miss like a bad firing plug so I replaced them

The Problem still seems to be there but it is less occuring..

I have added a Bottle of Petrol treatment to the tank to see if it doesnt stop it...

How hard is it to change the fuel filter on the Vitara's

I used to work in a garage longgggggggg time ago.
Never fill when truck is there fulling up under ground tanks, it's stirs up the water at the bottom of the tanks.
They usualy get pumped out every 3 to 6 months to remover water. Ave about 200 + lts.

Try a litre of Metho in ya tank. That should zap any water out. JMO

the standards these days means thats all crap, 10years in the game we never had a single car get dodgy or stirred up fuel and the filter will catch it anyway

if tis a real bad miss look at your plug leads for a crack or where its worn through on something

mine had a bad miss was a combination of dirty airflow meter and lots of airleaks from all the vacuum hoses having loose clamps, also a dodgy TPS sensor can do the same

It takes less than 30 mins to change the filter though. There is definitely a chance of crap getting in your tank, and if you've owned your car for a while, and plan to for a while, I highly recommend you replace the filter anyway so that you can eliminate that problem from the mix.

Yeah, it may not be clogged, but they're supposed to be replaced every few years.

in my younger days i used to get petrol in my bike at the same really old servo, and one day i cleaned the tank out and it was a compost heap in there

[royce]

I once cleaned a pulsar tank and pulled over 5l of water from the bottom and this really wierd algae that ate the plastic in the injectors and floated between the liquids

the young upstart swore black and blue it was dodgy fuel from our servo causing it and it had never been like this before, what triggered it was it was raining, and the rag he used as a fuel cap let water into the tank every time and it got to the point where the water hit the pickup point

[mrw82]

it would be very unlikely to get enough crap (in one hit) come through the pumps at the servo to give you problems, they have a filter on the suction side of the pump aswell as one in the nozzle.
filtered twice before it gets to your car.

as for water in the servo tanks coming through, the smallest underground tank is 24,000 litres, going up to as large as 110,000 litres, if they do have 200 litres of water in it when it gets stirred up from the delivery it wouldn't be anywhere near enough to notice.

CrikeyMike is right. simple to change the filter. You can buy one from Repco for $20 or go somewhere else like AutoPro and pay $65 (go figure). So anyway after you come back from Repco, grab an ice cream container and some rags, remove the fuel cap to depressurise the tank, climb under the back, put the ice cream container under the filter and undo the filter using the container and rags to catch the fuel. Note how it is installed and that there are two brass washers on each bolt. replace the washers with the ones that come with your new filter. 30 min is probably an over estimate.

If that does not fix it, you might also remove each spark plug lead with the engine idling to see if the revs die or not. If the revs say the same when you remove one of the leads, you have a spark problem.

Last time I had a bad miss, as soon as I got back to town I got a repco service kit and replaced oil, oil filter, air filter, fuel filter and plugs. The problem turned out to be an air leak in the concertina hose on the air inlet at the air filter end. If this has leaks, air gets to the EFI bypassing the air sensor and the computer gets real confused...
