  1. Question regarding throttle plate sticking & IACV

    Alfa 164 & 166
    Ok im having problem with sticky throttle off idle (only when engine is running). With the engine off, I can turn the throttle linkage by hand smoothly, without much effort. Its kinda weird, I think. Why would the throttle plate be hard to open only when the engine is running? Air is "pushing"...
