I have a 04 Ford Taurus and it just started running very rough. It sputters and vibrates and is not running good at all. I was driving and everything was fine and then all of the sudden it starting running very poorly. It makes a clicking noise while running and and basically barely sputters at idle. I stopped driving it because literally barely runs and now looking for help.
I hooked a OBD11 on the computer and the following codes came up.
It looks like the top 3 are cylinders that are running lean.
And the bottom two are misfire codes. It also says something online about o2 sensors.
I’ve read online it could be a vacuum leak. What are some areas to check and could it be something else?
