You're obviously not to knowledgeable when it comes to troubleshooting. Go by the basic diagnostic steps...if theres a miss, is there a miss all the time? only at idle? only at a certain RPM? Unplug each injector (one at a time at idle) and if the idle drops or sputters, that is normal, if it stays the same then you know that injector is malfunctioning, then check if its actuating etc, do the same thing with the ignition system, if you give me $50 i'll tell you exactly what the problem is.
