    Has anyone had any problem with replacement oxygen sensor on the left and right bank. This is my problem I replaced the left and right bank sensor with ones from a 1994 because the part house said they could not find the ones for the 1996. What is happen now is the engine is running rough a low speed. The GMC dealer replace the distributor with no correction of the problem. Any suggestion
