my Z tends to die after I give it heavy rpm especially on the high way, say I’m going about 65 in 5th gear at about 3k rpm and I push the clutch in and leave it in neutral the car bogs down real low till it eventually dies. Does not do this is I granny shift and don’t raise the rpm too high and it idles perfectly. When I get done driving I can sometimes notice the front passenger side injector looks a little wet while the others look totally dry, should I replace the injector or o ring will this most likely fix my problem? I just had a valve cover and gasket change because I had a spark plug covered in oil and it fixed my misfire so any help with this would be appreciated.
