    Car – Honda HRV 2004
    Problem – Gunked up throttle plate body
    Solution – remove throttle body for full clean

    (Excuse my ignorance and incorrect terminolgy…)[i]

    I’m trying to remove the whole throttle body, it’s simple enough 4 bolts give it a whack take off clean, put back on…

    I tried to take all 4 bolts off but could only extract 2 of them, the other two just the bolt NUT came off.

    Like this…

    On the throttle body I’m left with this…

    The bolt nut does not seem to have cracked off, it came off very easily as in the thread on the bolt sticking out is fine and the thread on the nut?

    So my question is how the **** do I get the bolt out?

    What I dont get is the two bolts ive taken off don’t have a thread up to the head, but the two bolts left in do…? (if that makes sense!)

    Again I’m probably doing something stupid here…

    Thanks for any help!

    How do you know the 2 remaining bolts dont also have a plain shank if you havent got them out?

    Do the bolts turn? If so just put the nuts back on a few turns and tap the ends with a mallet to knock em back.

    It looks like a stud to me, not a bolt. IF all nuts/bolts undone the body should slip off the studs but is probably stuck on with gasket

    Yes – its “one of them….”
    A stud.

    Seriously – if you didn’t know that why are you even attempting this ??

    do you have a new gasket? are you sure about what you are doing –
    do not hit anything with a hammer – it could get expensive – those castings crack if you hit them wrong.

    in summary – no replacement gasket – stop

    ah god im being dull aint i!

    you two are correct… ( think)

    there are two bolts which slide out and there are two studs which are part of the main body, so the throttle body slides off the two studs…

    just need to break the seal oin the gasket..

    Yes, its done that way for ease of location when assembling.

    Will it split at gasket now?

    BTW, if it’s a Fly-By-Wire body, please try not to wreck the position sensors by filling them up with whatever cleaning fluid you are going to use……….

    Also, if it is, and you clean a lot of gunk out, you might need to do a battery disconnect(or an OBD reset with a scan tool) to clear the current throttle idle adaption values from the engine ecu

    I cleaned mine out with just a rag and some GT85 – it idled a bit high for 5 minutes until the computer readjusted itself.

    voila…

    took for test drive and its a little better, but the accelerator is still heavy and not much modulation, it’s either the throttle body spring has been changed as it seems stiff or the inner cable is shot. But i lubed the cable and disconnected it it was smooth.

    cheers all
