    I have a 2003 Acura TL Type S with the same problem. At idle the car varies between 1500 and 3500 rpm. It is very dangerous, especially in heavy traffic. I have taken this car to a dealer multiple times in the past and it was finally fixed by a mechanic (at my third try at an Acura dealership) by adjusting the throttle cable where it attaches to the engine. He actually grabbed the cable wiggled it around while the car was running in park and the rpms were moving up and down like somebody was pressing the gas. The mechanic said he was familiar with that problem with these cars and knew right away what it was. That was back in 2007, over the last week the problem has re-occured.

AC switch inside car that turns compressor on flashed and shut down!Changed switch and does the same thing.

the car has a LOGIC module called AMP.
Airconditioning Module, PAIN.
its just logic.
it has inputs and it shuts down the compressor on all cars, made
for good reasons.
up to 6.
1: hi/low switch (freon) pressure too high or low.
12vdc on both sides of switch is manditory at all times on.
2:evap core, iced up. nah
3: A/C blower dead, (heater blower must be on)
4: ECU says engine overloaded. (hah, not parked)
5: A/C engine overheat switch, bad, and telling AMP engine is overheated. if not true the sender is bad or wire is grounding out.
6: some older Geos have throttle switch that can fail,
the A/c cuts at wideopen throttle.

we can get your A/c schematic. ask for it.
the geo tracker works simular.
see that here
learn how to fix this one and yours is same.

see 9 - 12 reasons there. even 13 with throttle switch .
ignore its too cold out for A/c to work. yes, amp senses that too.

on newer cars, even more reasons, (engine in limphome , tranny in limphome, and more)

1996 acura 2.5 tl upon start up the engine goes to 2500-3000 rpms then the engine rpms start surging between 1500 to 2000 then after several minutes it goes to a normal idle and runs fine.

Hi, I had the same problem, and is now fixed. Replace your idle control valve, and the idle problem will go away, and your car will be PERFECT!
