[QUOTE="scott degroot, post: 923385, member: 66039"] You had both rich and lean codes together at the same time for the same side of the engine which is usually not an indication of a vacuum leak. Typically when I see a lean and rich code at the same time it is caused by a faulty oxygen sensor. The proper thing to do would be to monitor the data with a scanner but I am going to assume that you don't have the capability to do that and do not want to pay to have it properly diagnosed so in that case I would start by putting in a drivers side upstream oxygen sensor, clearing the codes and then driving it...keep in mind that this is only a guess on my behalf. Keep in mind also that while you are only getting a code for one side of the engine running rich and lean it is possible that both sides of the engine are running rich/lean and it just hasn't set corresponding codes, in that case I would be looking for a dirty or a defective mass airflow sensor.
