either bad sensor or some sort of vaccum leak is making it run to lean on the passenger side of the motor.

Get the car lifted and crawl under it and see if the person who last worked on it damaged a wire to the 02 sensor, it is loose or damaged. If all is well, while under there just check the exhaust bolts and the two bolts which hold the H or X pipe you have to the header. This is an easy course of action and can help you eliminate these area's from the list.
