4.6 Stalling at Idle
Recently my 2003 4.6 has been idling rough, and times it will eventually stall. So, I replaced air filter, cleaned the MAF sensors, and replaced the IAC. Did not solve the problem. What else can I check before I have to take it to a shop? Do I need to wait for the "check engine soon" light to come on before using a diagnostic tool to read codes?
I would appreciate any comments. Thanks

Seafoam via the vac line did not help, in fact did not see any smoke out the back. I found the hose cracked at the PCV. Replaced PCV and all related hoses. That was the problem. it now idles smooth, no stalling
