I'm still having problems with cold start I havent checked operation of cold start injector yet. Wondering if it might be the ecu is bad I have a 561 and have heard here they go bad on 89's. How would you check? Or do you need to get a replacement and just try it out. What is the bosch number for the better replacement and do you simply remove the old ecu and plug in the new or is it more complicated than that. Is a boneyard ecu worth trying. I dont want to put a ton of money into my beater (as if I havent already spent a ton). How much should I expect to pay for a used ecu? Thanks Phil
