On certain Prelude SI vehicles, throttle body castings may contain slight porosity. During vehicle usage, coolant seepage may occur and eventually residue may accumulate on the throttle valve. The residue could cause the throttle valve to return slowly from the slightly open position to the idle position when the accelerator pedal is released. Correction: The throttle body assembly will be replaced.
