I wasn't trying to save money was trying to get oem parts they just didn't come in that way. I just cant figure out why the code will not clear. There shouldn't be a difference in pressure if the engine isn't running? If you think i need to check them I will. But it was running fine and no regin or engine lights ect. It only idled about an hour today after i changed the sensors and then went about five miles.
