I might be having the same problem only worse it seems. My engine compartment got all smoky today, and my car is running like CRAP! It happened all of a sudden like going down the highway.
That whole 02 sensor thing might be right up my alley. Its a good thing I have more of the gaskets for the exhaust.
Would this cause a car to seem to be running a cyl short? My car stinks like gas.
Sorry if i took this thread in an unintended direction.
