I have an 88 eldorado that I need hooked up to one of those diagnostic computers; it seems to have lost it "power" when I step on the gas. Only my reg mechanics computer only goes back 15 years, and he wants to be sure before he starts replacing parts, it has a tendency to be that when you fix one thing something else will happen so he wants to make sure he knows what’s wrong. My problem is that the only place that I know of that I would have a computer to hook it up to is the Cadillac dealer, and they charge 120/hr for diag work.... I live in Boston and wish I didn't have to spend 120 bucks just to find out the prob. then more money to fix it...??? Comments.
