I believe the car is running the stock ECU.

Just a slight miss on idle, makes it lumpy, shakes the car a little. Enough to be an irritation.

I tried to reset the ECU but for some reason I do not think it reset. Connected the green to green, black to black, under the steering column. Accelerator flat to floor, then half throttle. Fan was on and off, clicking sound, but "Check Engine" and a couple of other lights stayed on. No flashes, no nothing. Took it for a drive, no flashing "Check Engine". So bugger it if I know what is up.
