Idle problem again.

Well just when I tought my idle problem was gone, the problem is back again. I did another diagnostic again and I got codes 22 and 52 which are the Coolant Temp sensor and the Knock Sensor. I replaced the temp sensor and I am still having the idle problem. But what I noticed is that when i disconnect the coolant temp sensor wiring connector, the car will drop the idle to normal working rpm's(600 rpms). I checked my coolant temp sensor wiring and it seems good. After I finished insalling the coolant temp sensor I did a diagnostic again and I only got code 52(knock sensor). Help?
