I put a 1993 caprice lt1 engine in my 1994 camero which had a lt1 engine. MY PROBLEM BEGAN WHEN IT WAS CRANKED THE FIRST TIME. It sounded really ruff so the mach. Put all new injectors in and then it wouldn't idle so he put an air control valve and solved the idle problem but it still had a mis so I drove it for about a hundred miles and now it's just like it was before the new injectors what happened could it be the o2 sensor the tail pipes are pretty black I think it's rich fuel.
