    My check engine light1-4cylinders comes on for a second when I accelerate really hard in 1st or 2nd. Not all the time though. Car runs great without a miss. Any suggestions? Car has new plugs. Could it be ignition wires, coils etc?

    It could be a whole bunch of things. But I would guess that, MAYBE, you have a bad O2 sensor, maybe. It is best for you to have the code/s pulled to see exactly what it is.
