Got my 97 Q45 started... has a stutter idle, and some missing

[ddogz1518]

was having trouble with the car starting and running. Infiniti dealer found a wiring problem with the fuel pump relay to get the car running. But i noticed that the car has a studder at idle, like missing. and sometimes in mid range from 20 to 50 miles an hour it has a studder.

my friend had previously looked at it and found out that there was somthing wrong with the 8th injector. could this cause the studdering. Would it be a bad injector? how can u test?
