Stalling at stoplight
I guys. I'm a new f150 owner. I've had a 2004 5.4 for the past week. It has driven great until today when it stalled at a stoplight. I was able to reproduce the problem in my driveway by putting it in drive and holding the break. The rims slowly drop to about 450-500 and it dies. No oil pressure change or anything lie that.
Yesterday I replaced the airbag sensor and did the gotts intake mod and removed the intake baffles. I did have the battery disconnected for the airbag fix but not the intake work. Could it be something I did the the intake?
Appreciate your help. I searched using e iOS app but there wasn't much for results.

Common. Dirty throttle body (carbon buildup behind the plate). Get a can of throttle body cleaner, disconnect the battery, remove the air cleaner then throttle body assembly, (DO NOT REMOVE THE SIDE SENSOR/POTOMETER), spray the backside until it's clean, re-install, then go for a half hour drive so the PCM can re-learn.
If you search on IDLE, POOR IDLE, or throttle body, you'll find plenty of posts on this. You're not alone!
