I have a 94 sentra 1.6 L . It is running rough and missing at all speeds including idling. When accelerating I notice the problem the most with a loss of horsepower and a noisy vibration coming from the engine. I just changed the plugs a couple days ago and noted no improvement. I had this same problem seven months ago and it was solved with new plug wires and distributor cap/rotor. Those parts wouldn't be worn that soon , would they. I did a visual on the cap/rotor and wires and they look fine. Any suggestions ?
Thanks. Josh

 

No check engine light ? .... more description of the miss ?

 

I ended up having to replace the fuel injectors and went ahead and changed the fuel filter also. It now runs really nice, however, now the check engine light came on and stays on.
I wonder if its related to the work that I just had done?
