Your best bet would be to pull the plug and dry everything off. Then snug down the plug and drive up to auto zone and torque it. They should let you use the wrench.

Hand tight plus 1/4 turn. But you really need to check the torque as soon as you can.

Start the car and unplug #5 cop and injector and see if it evens out the idle. Then plug in one of them at a time to find out what isnt working.

What codes is it throwing? It still sounds like a vac leak to me. When you installed the injectors, did you lube the o-rings really well. Its possible you could have cut or nicked one..that will leak fuel/air and make it run rough. Let the motor cool and start pulling spark plugs and look at them. You may have fouled one. And dont worry about gettin a torque wrench. Just hand tighten them, then use a wratchet and snug them. Its not rocket science..

I guess The only advise I can give you now is uninstall, inspect and reinstall the new intake.
