    No I don't mean it's occasionally not there!
    Last couple of weeks it has been playing up at random, steady cruise, gentle acceleration, up it for the rent, anytime, it would suddenly cut out like no fuel or spark.
    To start with it was just really random and no codes, zilch.
    So started checking things that could interrupt ignition.
    Pulled plugs, they looked ok so put them back, ohmed the SE fat leads, checked ok, pulled crank sensor, nothing visibily wrong there.
    Checked the injector wiring, checked battery connections and earths, nothing, took it for a ride, seemed ok.
    Next ride she playing up again, a little more often than before, still no codes, changed the plugs, seemed ok again.
    Next ride and it's back, checked for fuel leak in tank, nope, filter is only 20k old so left it be, put a set of stock wires on it, walla, all good, away we go.
    Next ride it's doing it again, worse than ever and still no bloody codes. Checked all the wiring to the coil, everything checked ok. Took it for another spin and didn't think I was going to make it home, playing up like a 2 Bob watch and finally through a code as I saw the engine light flash a couple of times, turns out it was a MAP sensor code.
    Pulled the aircleaner cover off and had a squiz, the little sliding lock was in and the plug didn't want to come off with a gentle pull but it didn't look as though it was all the way in, anyway popped the lock, pulled the plug out, checked the pins, all good so pushed it back into the socket with a pair off needle nose pliers and it butted up properly, slid the lock home and fired it up, sounded ok.
    Cleared the code and took it for a spin, gave it curry and it's as good as gold, the MAP plug must of been it, I must not have pushed it home when I changed the intake seals, thing is it ran fine for weeks and the last mucking about I had done was CCP checks and it was fine before that so I was stumped.
    Moral of the story, if you seperate a plug, double check it's home when you plug it back in, some of these new plugs with their big seals can take a bit of effort to get them home.

    But if you break or bend something you should have remembered to be gentle.  The trick is to remember the right thing.

    Yeah so it seems, no code made it difficult, it was plugged in, just not all the way, bloody thing was fine for awhile, live n learn.

    Anything electrical is a pain in the ass if it's not obvious. and most guys would have laid down big bills to get that job done, so you should be happy.   I wonder how many parts the dealer would have replaced before (if) they figured it out...

    Hear you Hilly i have had this temp sensor in and out a few times as well the plug that goes into it is crazy tight to get in as well. I had to walk away a few times as i was about to paint the bike green and throw it in the long grass and hopefully never see it again! LOL

    i have found over the last few years that the connector/seals are a little firmer to reconnect and more so the square ones,oval and round ones are not to bad.a little bit of spit even helps or a tiny smear of dielectic grease can ease connection, oil based lubes tend to swell the seals a little.funny how the tight ones are always on sensors where you can barely get 2 fingers into them.

    What really helps when plugging/unplugging connectors is a quick squirt of CRC switch cleaner lube.
    It evaporates and leaves a thin film of lube.




    Thanks mate, good link that, had sort of slipped my mind what they have.
