Makes sense and misfire sounds right. It did seem to stumble longer then usually on start up. Then it ran extremely quiet but rough like it was missing on a cylinder. How long does it take for a CEL to clear on it's own if the problem is corrected?
For example:
Let's say I had to replace the o2 in my scenario.... After installing the new o2would I have to clear the code manually, or would the computer detect the new sensor?
