96 buick roadmaster
after it warms up, and goes into closed loop operation, the engine has an irregular miss. I read the codes, and found one O2 sensor faulty. Replacing it cleared the code, but did not fix the problem. I also tried a different PCM, with no improvement.
The engine runs fine until it warms up.
have the same problem?
