01 VW Jetta VR6, I'm getting a OBDII Code P1239 Cyl. 3-Fuel Inj. circ. Open Circ. Running rough loss of power?

I believe it is the injector but before I just go and spend $190 for the injector I was going to swap #3 with another and see if the code follows the injector. Access is limited and looks like the intake has to be removed. Very tight any tips on removing the intake and the injector?
