Thanks you it was both injectors like you said got two new one and now the truck has never run better! This site rocks and all for free I cant believe it.

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!

Makes explosions, pulls,

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.
