Hey Scotty! I need help indentifying whether I have bad fuel injectors in my 2002 Camry 2.4L, I'm getting very crappy gas mileage and the engine shakes A LOT at idle. I can also hear a buzzing/clicking sound coming from the intake manifold.

if you have a scanner, take a look at the fuel trims, is it running rich or lean and report back.
Hey I'm sorry I don't have a scan tool for the fuel trims, but I do think its running too lean because of the very bad gas mileage.

Check for vacuum leaks, use a spray bottle with water and spray around the intake manifold, wires, etc. if you hear an idle surge or hesitation, you have a vacuum leak.
