I have a 2001 ford mustang 3.0 V-6. The car will start right up and idle, but when I step on the gas it will stall. If I put it gear it will stay running but as soon as I try to accelerate it stalls. Any ideas. It was running fine till Thursday morning when I went to go work.

You MAY have a faulty IAC system. Perhaps a defective or dirty valve or maybe a dirty throttle body.

A sudden demand on a weak fuel pump may show this symptom.
