start with cleaning the iac

Change your fuel and air filter lately???



I would check the elbow, Most vacuum leaks show up when cold and go away when warm..

Then clean the IAC and maybe the Maf....

Ok. You have a coolant temp sensor that acts like a choke so to speak. When the engine is cold it tells the ECM and it tells the injectors to stay open a bit longer.



If you are sure your IAC is good to go then I would check or change the engine coolant temperature sensor. NOT the dash gauge sensor. They are very simular but do different jobs.
