The idle control or cold start system has a faulty and start with the basics.

Check the coolant level. Ensure hoses to IAC Idle Air Control and FITV (Fast Idle Thermal Valve, this is for cold start to increase the rpm) are not clogged.
Ensure the idle adjust screw has not worked itself loose.
Check for vacuum leaks.
If the MIL is indicating, retrieve the trouble code and let me know what it is.

Turn signal and hazard lights uses different fuse and if fuses are goos, you need to check the switch and its wiring.
