Engine Problems!!! Need Help!!!

[eweppler]

Tonight i was able to redo the connector to my coolant temp sensor and it was able to start up now but you can here a big air leak at around the throttle body area and also when you have the key turned on you can hear ticking coming from the engine bay and I notice that it is from the ISC because when I unplug it the ticking stops. Does this mean that my ISC is bad? Also would a bad TPS let air out of it because i think that is where the air is coming from.
