Ok i have a 95 civic ex, 1.6vtec. it's had the fluctuating high idle since i bought the car, and even with a rebuilt engine, it's still doing it. i've had the fast idle valve replaced and the idle air control motor replaced. it seems to not be as loud as before, but it's still doing it. when the car is first started every day, it revs up and down until the temperature warms up to where it should be. then the air intake tube makes like a soft pop noise and then the fluctuating stops. and then the idle of the car goes down to about 200. i can manually raise the idle to about 1000-1200 but within a month, it drops back down to around 200. everyone has told me to change the throttle positioning sensor, but all the parts stores have told me there isn't one on a 95 civic. i don't know what to do next or where to find a new tps. please help! thanks.
