Please please please take my advice and dump that car as soon as possible. In about 5 months your gonna be able to set up magic shows behind that 7 and disapear through the smoke behind it. I'm telling you from personal experience. What starts as a p0491 will turn into a p0491 and p0492 and you will try to replace the whole secondary air pump system only to be out $1500 than the smoke will come. The problem came from whoever owned the vehicle before waiting 15,000 miles for an oil change. It ruins this car. If you dont' believe me do some research on this forum, but im doing you a favor now. I know she a beautiful brazilian girl with a fat ass, tan skin but she has aids. Don't get the sickness.
