Started running rough, replaced plugs, wires, button and cap. Still running rough, made sure timing was right. Still running rough, checked to see what code puts out. Comes up as 512 ECA problem, Keep Alive Memory test failure. Unhooked battery to clear code but comes up the same code. I have one person saying a motor mount is busted causing the timing not to set. Then I have another person saying a tranny mount is busted causing the rough idle. I don't know what the problem is, I just want my truck fixed. About a year ago the computer under the dash was replaced along with the distributor. I am a female but I do know about some stuff and I have a book for my truck. But at the moment I am stuck. Please Help.
