Definitely bleeding issue. I bought pressure bleeder and that thing is a waste. I tried bleeding twice with it and there were still pedal issues. Got my neighbor to help me bleed the breaks the old fashioned way, no issues since!

^^^^ got you, what im gonna do is wait a couple days for proper bedding, check all my connections and than get some new fluid and have my wife help me with the bleeding process. From all these negative comments im getting on pressure bleeders i wish i never bought the stupid thing. My dad was like why the heck didn't you just do it the old fashioned way, its much easier and you save $30

Hate to give you more bad news but if you have introduced air to the abs pump you are wasting your time, that pump will have to cycle to get the air out.

If the only thing you had done was to bleed the system, I would agree that air is definitely in the system and causing the poor pedal feel. However, since you changed the pads and rotors too, I would strongly suggest you bed them in with a couple of days of driving before you make any decision to re-bleed it etc.

I've done many brake changes on other cars including Porsche Brembo BBK conversions on my previous car, and had this exact same issue before, but found it to improve hugely after a couple of days of town driving with lots of (light/medium pressure) braking.

If it does not improve, then you need to re-bleed as everyone else says.

Good luck
