The cold start fast idle valve, throttle body and EACV are the 3 items you need to check.
1. Fast idle valve most probably has its internal valve worked loose by itself due to a bad O ring.
2. Throttle body might be stuck in open position due to debris from a bad air filter.
3. The EAVC might be stuck in open position due to internal fault.
