Idol Speed Actuator?

[DDK's 525]

Ok, I finally able to figure out the code thing with the gas pedal and came up with the code 1262 which is the Idol Speed Actuator. Is this the same as an Idol Control Valve listed here 1990 BMW Product Categories - Bma Auto Parts (http://www.bmaparts.com/ShopByVehicle.epc?q=&yearid=1990%40%401990&makeid=BMW%40%40BMW%40%40X&engineid=1012037%40%40525I+%2FL6_2.5L_M20%40%40525 I&keyword=idle&subcatid=Idle+Control+Valve@@Fuel+Injection&mode=PA)? If so, where is it and is it easy to replace?

Thanks for the help.
