    Lads, I have a 1996 1.3 4e-fe na starlet and its idling high all the time, i'm guessing around 1100 to 1300 rpm(no rev gauge).

    any ideas what might be the cause. She's in very good condition, only 116000 miles(genuine).

    Plugs are fine
    Compression is fine
    Oil is fine
    Cant find any vacuum leaks(unless i'm missing something)

    Is there any common faults with these, can't find anything on autodata.

    Check if throttle is closed when it should be.

    Check throttle's overall condition and clean it up.

    Check if ISC valve works properly:
    Haynes Manual wrote:
    27 Using a jumper wire, bridge terminals TE1 and E1 of the test connector (see illustration).
    28 Start the engine. The engine speed should increase to approximately 1000 to 1200 rpm for five seconds then return to normal idle speed.
    a) If the engine speed changes as described, the ISC valve is okay.
    b) If the engine speed does not change as described, remove the valve as described
    below.
    29 With the valve removed, reconnect the wiring plug.
    30 Turn the ignition on. The valve should move from fully open, to fully closed, then to halfway closed in that order, with a gap of 0.5 seconds between each position. If it does not perform as specified, renew the valve.
