IAC for a 525 Design I or II ?
 
Since my idle surge +/- 200 rpm , i look to exchange my IAC , but need to know what is the difference in the Design I or II , it`s the same things ? part 15 and 16 ?
Many thanks in advance

Just to add note , the problem is , the motor working great , but when i put trottle off , the rpm stay at 800- 1000 , and after 15 to 30 sec they go back to 600 , this is why i think is my IAC ,,,that made sense ?

Get a can of throttle body cleaner ant your local ap store,if your throttle blade is built up with oil and carbon it will hold the throttle blade open which will cause it to surge,also it will throw the tps % off then the pcm will think the throttle blade are not closed...
