    2003 GTI LE RFI Help

    I am thinking about buying a 2003 GTI RFI from a guy on craigslist. He claims the ski starts and idles but doesnt run out on the top end like it should. I know that the RFI's only idle on one cylinder so i am guessing the second cylinder never kicks in . He claims good compression on both cylinders. Does anyone know of any regular issues with this model that would be a quick fix? Or is it a shot in the dark.

    You need to find out if anyone has been into it, the rotary valve timing could be off not letting it tack out. you need to check the compression yourself to be for sure. also test ride it yourself, wile its on the trailer in the water you can check the firing at quarter throttle if you have spark on both plug wires and missing on one cylinder you can swap the injectors if the missing swaps to the other cylinder it could be a injector going bad. just make sure you use new plugs.

    The guys on the seadoo forum may be able to help you with it.
