David Austin Red

I知 new to the Forums, and I had just gotten a 2006 Mustang GT. I have been building her for awhile and finally got the engine rebuilt to my liking. However, the vehicle seems to stall and is having idleing issues. It値l sit in 1 place and idle all day long, but as soon as I push the clutch to drive it, as soon as I let off the gas, she dies on me? I致e replaced everything I can think to replace. I知 not sure where else to go. I can drive just fine until I need to stop or slow down. I致e replaced the Throttle Position Sensor, and Mass Air Flow Sensor. Idk what else it could be. Any help would be welcomed.

My dad says maybe fuel filter?
Throttle Position Sensor maybe too

what do you mean by "rebuilt to my liking"?

If the engine is modified, you will probably need a tune.
