P1272 high to low open on #2

I was looking at a very old post on the p1272 code.
Looks like some were saying it is most likely electrical not hydro. I started running rough going down the road the other day. It is now intermittent. I did the buzz test and I get the code on #2 injector. When it's running bad you get a very quite buzz on #2, and when I run the test when it's running good I get the same strong buzz on all cylinders but still get the code. I have replaced the VC gasket/harness. Still get the code but is running smooth for now, could it be a bad injector or should i keep chasing the electrical, any body get this figured out? ideas sure would be appreciated Thanks
