check engine light update. I found the vacuum leak. It was one of those 2 big tubes connected to the engine, one must have been loose and came totally off a while ago. Since I fixed it (4 days ago) and reset the electrical system to take of the check engine light sign, it did not come up again. So I hope I fixed it.
However my engine does not make a good sound.
I made an audio/video to listen to it. Please let meknow what you guys think. Oil was been changed a couple month ago. I drive only 5 miles a day.
