maybe coolant temp sensor or idle speed motor, do you know if this is a california emissions spec vehicle? If so it will have extra pre-catalytic converters after the exhaust manifolds that sometimes cause problems. Honestly I have had several like that and sometimes its nearly impossible to find the problem, if it runs ok as soon as it warms up just let it run a few minutes before you drive it.
