Does anyone have an extra ecu for an 81 deville 8/6/4 laying around? I will buy a working one if anyone has one. I think mine is caput, when I run codes it gives me codes that don't exsist and runs pretty bad. I am waisting alot of gas. And it sprays sout on the ground from the exaust, I was thinking the smog pump on that, but not sure. Any help would be greatly appricated.
