Recently replaced the pcv system and fuel injectors, engine now shakes at idle and can be felt through the steering wheel, it does not look like any vacuum leaks are present, is there a common cause for this after PCV system replacement or fuel injector replacement? The fuel rail popped off the fuel line, I couldn't find anything on putting it back on correctly so maybe there is air getting in through there throwing the air/fuel mix off? I appreciate any help trying to solve this.
