Hey guys im a new member here and i have no idea about car engineering...so im looking forward to some help from you experts out there..my ECU (engine control unit) for my eclipse 95 automatic, is gone. and I'm wondering what would be the best option for me..buy a new one? buy a used one online somewhere? or go to a junkyard and take it out from an old eclipse? if so please also tell me were i can find them cheap online and where it is located in the car because i would have to go my self and look for it in the junk yard.

thank you in advance.

 

first off how do you know that is the problem. Also what model eclipse do you have, RS/GS/GST, ect?
