rough running again

well my 94 Century is running rough again, but it is not the fuel pump. It misses almost all the time. it will run fine at idle sometimes. It has new plugs, wires, fuel pump, air filter, IAC valve, and coil packs are fine. what now? dirty injectors? bad injectors?

Running rough, very general, is this a dead missfire like a wire or plug, any check engine lites?

no lights, and it is not all the time.

it is dead cylinder. like it is not getting any fuel. I don't think that fire is the problem.

Does it ever clear up if you get on the highway, and hit the accelerator hard?

I've had the same problem with my Century, and it seems to be very sensitive to gas from different stations. Injector cleaner clears it up for me.

Ditto my Century. Always cylinder 2. Injector cleaner clears me up as well..
