This is the 3rd time this happened. I ended up going to work late once because I did not want to be on the hwy. with the engine not hot enough. So I drove around the block for 5 mins. Also the check engine light was on. The first time it happened, I was just lucky that a kind gentleman told me he had the same experience and it was because of the weather. I got rid of the check engine light by disconnecting the battery for a few minutes. The authorities should look into this.
