How long does your SVX high idle?

[Dr.Outback]

I've been slightly annoyed by my SVX's long high idle time. When cold, under 45 degrees, the car will stay on high idle, 1700-2000 rpm, till the engine heats up enough for the climate control to come on to blow hot air. Usually about 3-4mins. I can take my foot off the gas and let the car drive a little on it's own. Like cruise control. I replaced the auxillary air control valve because that closes after the engine warms up, and only provides extra air for cold starts. Anybody else experience this? Is this a normal high idle period for this engine? I have no other SVX to compare it with.

At temps below 45F, mine runs a high idle for maybe 2 minutes, but its only above 1500 rpm for maybe 30 sec.

Dunno. My 92 idles at 700 during the day, and when cold it will stay at about 1200 for 3 to 4 minutes. If I let it sit in neutral warming, it will stay in the 700 range until warmed. Check all the vacuum lines, and don't use the warm air until it reaches temp. Yes, it does get into the low 20's here, and this is the environment I am talking about.

Thanks for the replies. It's hard discerning what is "normal" with no other SVX's to compare to. I guess I'll have to hook up to the scan tool and look at the sensor data. It idles rock solid and steady after warm up. I just don't like the fact that after driving for a few minutes I can put it in neutral, and it's idling at 1700rpm or more when still cold.

I've seen high idles of over 2000rpm with the manual transmission. I seem to be able to raise the idle by dragging the clutch without pressing the gas (forcing the engine to maintain idle). I can only seem to drop the idle when driving by coming to a complete stop (speed sensitive). I can also get around this by toggling the switch I installed to fool the ECU into thinking I'm in neutral.

This is different then that. It doesn't idle high when warm. Only when cold. Just after the temp guage gets to the line, it stops idling high.

I don't get high idle when warm either.
