Idle problem.. can anyone give me some help here?
Hi guys, bought my s2k like 2 months ago. it's year 2000 and has around 9xxx miles on it. Now it has about 11000 miles on it. The idle problem doesn't happen a lot but when it happens, let's say i'm approaching the stop light.. if I don't downshift and just shift the neutral and let the rpm drop, it will drop too low and the engine shakes, then rpm goes back up. it happens sometimes when I 'm backing up my car too.
I have already replaced new spark plugs, cleaned idle air control valve, throttle body, reset ECU, ....
Anything else will cause this problem? by the way, the car is bone stock.
Pls help.
Thanks

The car's fine (at least it sounds that way from your description, but without driving it myself I couldn't say for sure). When it's happening when you're backing up, it sounds to me like you're just bogging the car. Put your foot into the throttle a little more and slip the clutch.

Try the MAP sensor "whack". It's the thing on top of the throttle body with the wiring harness going to it. Unplug it, give it a few good thumps with the rubber handle of a screwdriver and plug it back.
It may also be the idle air control mechanism or it may just need a few more episodes before it learns to hold the idle up in those circumstances.

I vote for xviper's second suggestion. Has the weather changed near you recently? I typically see this on a warm day after a cool spell (never gets COLD here). The ECU has to re-"learn" the proper timing to catch the idle smoothly in the new temp/humidity conditions.
