The part that makes it run "rough" is the fact that you eliminate the AWS (accelerated warm-up) system. I did that in my car (did a partial simplification) and can say that sometimes when it is cold, the car will stall when first warming up. It's no biggie...just a side effect that your engine doesn't shoot to 3000 rpm when it is stone cold. After the AWS elimination, mine revs up to about 1800 when cold.
