New to the group and looking for some insight

[Mnolan]

I am new to the group , I have an 05 mustang gt that has recently been giving me trouble on cold start. Starts then throttles down and stalls out. Once I get it going it runs fine. I changed the plugs , the fuel filter and fuel rail sensor
Any thoughts?

Remove the throttle body and thoroughly clean the inside of all dirt, especially between the blades and bores. Since it doesn't have an idle air bypass valve like older throttle bodies, any accumulated dirt can cause an uneven idle, low idle, or stalling.

First strep in diagnosis. ALWAYS SCAN FOR TROUBLE CODES. Even if the Check Engine Light is not on, check for any underlying codes. Codes don't tell you what is wrong but they help with a direction to the cause.
