I think I have a shortage in my fuel injector wires where would I get a new harness or should I just locate new wires and tap into the harness? How do I know I have bad injectors, when I got the car it had allot of power in it now its dragging. I got an air intake, NGK plugz and wires wat else do I need to give me more power.

Fuel injectors can be tested by putting a long screwdriver against one and the other end against your ear you should hear the audible clicking sound as they open and close with the engine running also have you changed the fuel filter recently?

Check the timing with a light as for the chain I have a 95 maxima and had to change it out it may be bad because the older models did not use the stainless steel
