high idle issues, code P0507

I am currently getting a P0507 code after cleaning the MAF sensor and cleaning my throttle body. I used MAF cleaner on the sensor and throttle body cleaner on the throttle body. I used a clean rag to clean the throttle body. Put every back together and got the p0507 code. Tried to do a manual reset by pulling the negative battery cable code come back the next time I started the car. When the car is in park check engine light on, idle.is about 1,200+ and when I'm driving the idle is sometimes 1,000 to 1,200 rpm's and sometimes it sits at 900 to 1,000 in drive. Different idle almost every time I start the car. There's is slight hesitation and when I apply the brake pedal idle kinda jump around and settles, when I let off the brake the car takes off like it's ready to go.
