New TPS and idle is now higher

So I got my new motor back 5.2L and installed and it was idling at like 1000-1200RPM in park but would drop to 500 in drive. I replaced the TPS thinking that would be the problem. Now the idle is at 1500. What now??/

Well if it hasn't been cleaned before it can't hurt. It's free too.
