Can I replace 1 fuel injector?

[Gus]

Truck is an 02 Dakota with 4.7L about 85k. I just replaced the spark plugs this weekend and noticed 1 of them was wet with fuel. I'm pretty sure that means the injector is leaking. Probably the source of my extended crank time if I don't let the fuel pump prime the system before cranking. Question is, can I just replace the 1 injector? Logic tells me that I should probably do all of them as the spray pattern would be more uniform. But in reality, does that really matter?

$45 vs $360 for all 8 if I do it myself. I'd rather spend it on hunting/fishing trips.

Thanks for the responses.

You can just replace 1.

I replace them as necessary all the time whether its 1, 3, 6 or whatever.

I would check to make sure that the injector is not grounded all the time by the computer?

and make sure the spark plug is firing.
