I've been stalking the forums for a few weeks now. I've got a 91 Maxima VG30E. About 2 months ago, I noticed that the car would sound very bogged down until I drove it a few miles or rev'd the engine up a couple times. It went away and I thought nothing of it for a few weeks(thought it was bad gas, maybe). About 2 weeks ago, it started bogging down and didn't stop. Now, I've changed plugs, wires, checked the distributor cap, fixed a vacumm hose(which seemed to help things quite a bit), changed the oil, used a fuel system cleaner, and checked the injectors. After I changed that vacuum hose (the one running to the intake valves), it's back to sporadically bogging down.

I've narrowed the problem down to one cylinder not firing. The injector is not leaking gas (I checked that using advice found here). I haven't ohm'd out the injector yet because I haven't gotten my hands on an ohm meter yet. I disconnected it while it was running and couldn't tell a difference (still bogged down), so it must be that cylinder. I'm thinking that the injector is bad and not opening correctly. I won't know for sure until I ohm the injector. Does it sound like I'm on the right track and does anyone have any suggestions? Thanks in advance!
