bad injectors?

So today i changed the fuel pressure regulator, spark plugs,dist. Cap,and rotor button and im still having the same problem. My next thought was my injectors...how would i go about testing them, and if they are bad what is a good brand for a decent price?
Thanks

Unplug them one at a time with the engine running and see if your idle changes or not if it doesn't it's not an injector. If it does change on every cylinder but one you've found your bad injector.

Until you pull the codes you will be throwing money at a problem with an unknown source. Also suggested by JohnSmith3524 in your other thread.)

After reading your previous posts I doubt it's a bad injector. It would run bad all the time not just be difficult to start. If it's a 96 it's OBD II and Auto Zone can read codes for free for you.
