Our 01 V10 Ex developed a cold start stalling problem where the rig cranked and lit fine, but would immediatly stall unless you got on the gas and held the idle up till it warmed up. Searching here led me to the Idle Air Control valve. Evidently it is quite common for the IAC to get carboned up on the Triton engine family. I pulled the valve and cleaned it with throttle body cleaner and q-tips, probably a 20 minute job start to finish. Since then we've had zero cold start issues, it appears to have solved the problem. Thanks to all those who have discussed these type of issues here for others to learn from.

 

Cool! Glad you're back to 100% driveability!

Never had the issue on either V10 but look forward to the problem because it's such a simple fix.
