Sounds like a vacuum leak or MAF problem.

You could have knocked something loose. You must have removed the air cleaner and/or some part of the intake to get to the passenger side bank... Did the MAF get plugged back in right? What about the hoses to the boost solenoid? Maybe the hoses hanging onto the turbo inlet pipe or if stock, that hose itself might have cracked in the flex section.

Unplug or wiggle any other hoses to move the socket wrench?

Out of curiosity, did you check the gap on the new plugs before installing them?

Did you reset the ECU?
