need idle set

[85t-typebuick]

I have a hot air and for the past 6months the idle seems to be off, I also need the IAC reset since I replaced it. The car will run fine for the first few minutes but once warmed up the idle drops down, and when braking or sitting at a light sometimes will stall,

You need a scan tool. The IAC and the TPS need to be adjusted together. Do you have one?
