Finally took time to replace the O2 sensor on the 94cs n/a with an OEM Saturday. The 94cs still has a May, 94 sticker for failing NOx in NJ. There is significant amount of work. Had to loosen the serpentine belt and the alternator to get to the wiring riding on the heater tube on the timing chain cover. Took me a good two hours.
Sunday morning I noticed the check engine light was on, two flashes. The code says MAP sensor. Beyond that I have no idea for further diagnostic. Ideas anyone?
I also found the exhaust to be louder than normal. Tracing the source I found it came from the mid-muffler. But there was no leak. Knocking on the mid-muffler when it has cooled down, I detected something is loose inside rattling. Guess I'd have to live with it.
