idle speed control motor

I have a 93 dodge shadow 2.2. Lately when i start it up, it won't ilde or
when i go to put in gear it dies, but if i give it a little gas when i
start it and put in gear it won't die. Once i get going it does fine. I
had auto zone do a code check on it. According to what they found out,
it's code 26 i beleive, idle speed control motor short ciruit. they said i
needed to check with a dealership to get a new one, and i did. I was just
wondering if i could find one a little cheaper than the dealership, and if
i can, could someone please tell me where..... and also how would i have
someone replace it without having to pay the mechanic at the dealership...
any help would be greatly appreciated.... thanks
