A high idle could be due to many things but a major cause is a vacuum leak causing too much air to enter the fuel system which in turn causes the computer to overcompensate with fuel. Take it to an auto parts chain store where they will do a diagnostic scan for free and see if any error codes are present.

Where is the coldstart relay situated on a 2006 bmw x5

There is no cold start relay. Cold start mode ( open loop, rich, high idle) is controlled by the ECU. A coolant temp. sensor signals warm up to shift the ECU to closed loop mode(warm, lean, normal idle). Check the coolant sensor and correct coolant level. The thermostat controls warm up time.

I have a 95 bmw 525i and when I start it it is throwing sparks what could this be? Also it is idling high especially after you push the gas pedal or push the clutch in, what is wrong,

Where is it throwing sparks from, under the hood, under the transmission, from the alternator, etc.? Since the idle speed could be related to some load that is generating the sparks, I wouldn't treat them as separate issues yet. But you need to do some troubleshooting and provide more information for anyone to give you a decent answer.

93 monty idles high then dies on cold startup

I would check the idle air control valve. The computer controls idle speed by regulating the amount of air entering the throttle body by using the valve. It could be sticking or failing.
I am assuming you have a 93 Monte Carlo.

Usually it is a sticking throttle plate, vac leak, or a problem with the idle control valve.

it's not old carbureted chevy, it's not idling high because there's too much tension on the gas pedal cable.

BMW E46 fault code P2799 - what does it mean

If is for a 3 series compact (318ti most common) then
P2799 is the intake air tem sensor 2
Which would explain the high idleing. Probably a sensor problem (bmw will charge) a competant mechanic should do it easily.

Where is adjustment for idle located in 528

Idle speed is not adjustable, it is controlled by the fuel injection computer, even if you tried to adjust it the computer would over ride any adjustment made by you. I assure you idle speed has negligible affect on fuel consumption
