2003 S10 2.2L low speed miss

Open the oil filler lid and see if the noise goes away - or lift the oil dip stick. It could be a gummed up PCV system that causes pressure in the crank case that "whistles" when the engine is running.

By opening the lid or dip stick, you're letting the pressure out and the whistling should stop.

If this is the issue, FCP Euro has a PCV replacement kit for about $350.

2003 suburban idles to low.

the idle speed is computer controlled and not adjustable, slow idle is caused by a dirty intake, do the following.

Here are some of the causes of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

Could be a vac leak or other ignition problem.
A vac leak could be covered up by the extra fuel and higher idle speed when the engine is cold. And if it is a gasket leaking the leak can get bigger as the engine warms up.
A faulty plug wire or coil could start failing when hot.
A solid miss-fire should make the check engine light come on and set a trouble code.

If you ever have an oil leak it really should be fixed right away unless this happened all at once. Go to a local mech or if there is an Autozone around go there and have them check the Engine Light code for you for free. You will have more info to work with.

SOURCE: Noisy engine idle and stutter at low or high speed

I had the same problem (X-type 2.0d 2004). The stutter was cured on mine by getting the ECU fashed with the latest firmware. This is a known problem and the update does cure it (£28), I didn't bother with all the tests the garage wanted to.
The noisey engine at idle is the alternator belt. It resonates at idle and causes the noise, There is a modified bottom pulley, tensioner and belt kit, but it is rather expensive ~£200 plus fitting (around 4 hours labour). Mondeo's have the same problem but that kit doesn't fit the Jag.
Hope this helps

SOURCE: Caravan runs rough at idle or low speed

Check for dirty throttle body, or IAC motor. Possibly getting raw gas into the EVAP system after fill up also.
