It starts up faster now, idles stronger when cold, there was also an improvement in performance.
The ABS light would randmly come on while starting up first time in the morning. That's when idling was low and rough and motor wasn't pulling strong. When the light went out after a few secs to a minute, idling and performance returned to normal as if nothing was ever wrong. This got worse and the car became hard to start when ABS iluminated and the stalling also manifested itself. It got so bad that the ABS light wouldn't go out for quite a few kms, and the car wouldn't accelerate.
