There were injector No#2 has faulty on diagnostic tester, cause current parameter of no#2 injector doesn't change when engine idling and high RPM. Also no#5 injector has same result but when I do cut off test No#2 has no changes other cylinders are OK.

It sounds like you have two injectors not working here is a guide to help you test them.

Some say the diagrams is from under the engine so keep that in mind.

Please run this test and get back to us.

Where is cylinder number 2 located on the 4.7 l V8 engine? That will allow me to follow the exhaust to locate the oxygen bank 2 sensor 1 that I need to replace. Thank you!

The firing order is 1, 5, 3, 6, 2, 4. To make suer you have the correct order pull #1 spark plug and pull off the coil lead from the distributor and earth, have an assistant crank the engine in short turns, just a flick on and off and place a finger over the plug hole, when you feel compression building up, turn engine until crank shaft pulley timing marks align. Remove distributor cap and check which segment the rotor is touching, this will ne #1 cyl. Crank engine again to ensure you know the direction of rotation of the rotor.
