    Default Guess I have water in the Carby

    Just had a horrendous drive in Sydneys big wet in the CX....lots of puddles and lots of rain....just as I was nearing home, going up a hill the car seemed to pull and lost power and then stalled.

    I got her going again....no problems on a flat road....but as soon as I drove on a slight incline, she started to splutter again.

    Took some downhill roads back and got her in the driveway without incident.

    So do I let her dry out or what. I guess it's water mixing with petrol

    Haven't had this problem ever before ( actually I did in a Torana in 1984 )

    If there is water in your fuel, it should behave badly regardless. Dumb question, you may be low on fuel? If there is water in your tank, adding some meth. spirits will do the trick I have been told, but ask around first, dont take my word for it.

    Spoke to my mechanic, possibly a blockage in the fuel filter? He said it would be pretty impossible to get water in the carboy.

    Will wait for the Mrs to get home at 1 and get a replacement and fit it.

    Still don't understand the dragging feeling I got before it stalled.

    No, not by driving through the rain, but through contaminated fuel you will.

    Water in fuel will result in loss of power regardless of the terrain. Metho will blend with the water and the fuel and the car is so drunk it doesn't know the difference (joking aside, it does actually work).

    As it only happens up hills, most likely a blockage in fuel filter. Replace it and see what happens!

    Sydney was dire this morning and driving should be avoided unless absolutely necessary, just abotu wiped out by a camry that didn't look when changing lanes!

    Surely wet ignition Stu. I had a very wet drive to work this morning but no issues. I was stopped a few years ago with the same symptoms. On light load the feeble spark can start ignition, put your foot down, more fuel and the spark can't do it, so she starts to miss.

    It could be moisture inside the dizzy cap causing loss of spark energy.

    That would be the first thing to check, also the long leads to #3 and #4 could be wet. Do you have a spare lead set?

    It should be easy enough to pick by the way it runs. Is it missing like an electrical miss, or dying on all pots ?

    Either way, the fuel filter is under the back of the car, infront of the fuel tank. You need engine stands or ramp to get to it.

    FIXED.....Junk in the jets, and the butterfly not working properly. No water in there though

    So thanks to Sydneys best mechanic.

    Was also a good excuse to change the wiper, replace the plugs, change the oil and also the front fuel filter

    There shouldn't be a front fuel filter unless someone has added it .... You NEED to change the one at the back. It'll be so old it'll be breaking up internally and filling your fuel line and carby with crap .... Any added fuel filters at the front won't stop this (infact the final step will be the factory fuel filter blocking completely and leaving you stranded!).

    blockage was most likely from the pollution filter

    Water can certainly end up in the carby (or EFI system) in a CX. It can accumulate in the low horizontal rubber tube between the tank and and neck because the cap seal is leaking or the neck is cracked. The tank has an anti-syphon design, so the entry to the tank is like a weir and fresh fuel spills over into the tank when you fill it. If there is water in the neck, it's most likely to move to the tank and then the carby when you next fill it up. If you just drain the water from the tank and carby and forget the neck, then next time you fill it the problem will return.
