    My honda on a cold start idle fine. When it warms up it start fluxuating
    drastically @ 1000 to 1500 rpm. I was told it was a throttle body sensor
    and that you had to buy the whole throttle body to get the sensor for that
    year. Need help. thanks, steve

    FITV or IAC needs cleaning.

    I have 2 complete 1.5L DPFI setups if you figure out what parts you need.

    double check the coolant level in the radiator [not the expansion
    bottle]. insufficient coolant sends the wrong temp sensor signal to the
    ecu & it goes into cold idle mode until the revs rise enough to bathe
    the sensor. than it drops & the cycle repeats.
