I recently had some engine work done on my 98 Ford Ranger. It has 108000 miles on the engine and I had some gaskets replaced on the valve covers and there was a coolant leak. A week after the repairs the Check engine light came on and that following Monday I had it back in the shop. I'm disable so I don't drive that much.
The check engine light came back on two days after driving it again. I lift up the hood and notice a hose that looked like it was not connected to something or something was left off of it.
I took it to Autozone and had them hook it up to their engine analyzer. The code came up PO174 Fuel System Too Lean (Cylinder Bank 2)
Here are some picture that I'm sure will get me some answers. Please!

A loose or disconnected vacuum line will cause a lean mixture. If it's reconnected, disconnect your battery to clear the codes and reset.
The Battery has been disconnected and the codes rest by the mechanic.
Can you see the link to my pictures?
Thanks for the reply. I felt something was left off. But I have the 4.0 liter engine. I was hoping for a more precise answer.
