Question about 1989 Cadillac Sedan DeVille
My 1989 Deville has 53,000 original miles. The majority of times it runs great. However, there are times when it stalls on the open road and other times it races and misfires like a bucking bronco. It gets to a point where it becomes unreliable to use. However, it never fails to start. In the past year the ECM and the BCM were replaced. I just replaced the fuel injectors and it ran like a champ for a week but it is back to its old unreliable self. I am going to replace the oxygen sensor and fuel filter next.
Any helpful hints would be greatly appreciated.
