Pull the plug on the injectors one by one to see if there is a change in idle. If no change, then thats your bad injector. You can also test the resistance (horseshoe symbol) on the injectors with a multimeter, 11.5 ohms or something close to that is a correct reading.

You need to perform a ver simple test and stop getting ahead of yourself
remove the fuel rail from the intake manifold and turn the key into on so you have your fuel pump powered up and providing fuel to the rail.

Then watch the pintle cap area of each injector on the rail and look for any fuel dribbling out or leaking around the edge of the pintle cap area of the injector tip.

I am pretty sure this is your issue, injector leak at the tip of the side feed inj

Just checked the injectors and they aren't leaking.

Thanks guys. Will try both of these fixes when I get a chance.
