This is the 3rd time that I've gotten this code in 2 months. The first 2 times I had a slow response on 02 sensor with it. Yesterday the only code was a misfire on cylinder #5. It did skip the other morning for like 30 seconds after it was started up but it did go away. The engine light came on later that afternoon. I ordered a new O2 sensor for the code the other day but it hasn't come in yet. What could but causing this misfire condition only in the morning sometimes?
