Are they for the fuel injection?I am getting a signal that Cyl 5 fuel injector is malfunctioning but according to the cylinder layout, it is on the other side of the engine.(This info came from Autozone.):-

check that #5 injector is completely plugged in and that its not leaking. does the car run rough?

looking at your photo and then at the wiring diagram, you have the wires in the wrong holes, white wire on write side looking at the injector, and the blue wire on the left.also looking at your photo l see you might not have the wires all the way down in the connector. swap the wires slide the rubber seal up the wire then push in connector,then slide the seal down in the hole, have any questions e-mail me

The cylinder locations r rear bank 2,4,6 front bank 135.as for the wires on the injectors,they r solenoids they do not really care where the power comes from so long as it gets power it does not really matter if they r in the wrong spot,if they were not on the right injector u would have a code for two injectors.The common problem caused by removing the intake manifold is the wires get broken in the injector harness connector(black color mounted to the manifold on the right hand side looking at the engine from the front.Use a multimeter & check continuity from this connector to the injectors.
