My truck just recently developed a noise coming from the front passenger fuel injector. It used to be completely quiet, but now it sounds like fluid running through a restricted valve. This is the best way that I can describe it, it is not ticking or rattling!

Should I try putting a can of fuel injector cleaner in the tank?

Should I replace the injector? If so, is this an easy job and how do I do it?

Thanks in advance for any help.

 

it is normal to hear a tick from the injectors.

if you are worried about it put a bottle of Red Line SI-1 Fuel system cleaner in teh gas tank.

As long as you are not misfiring or the injector is not leaking, you are fine.
