Hello guys I have a quick question about my 99 ford mustang.

Car is a 99 ford mustang with a 3.8 auto

Symptoms are 1. it will hard start when cold (sometimes cycling key will help)
2. when going 40-45 mph with it in over drive if you press on the gas to accelerate it will stutter and act like it is running out of gas.
3. sometimes when it does start it will run rough then die

All of these symptoms started about a 3 month ago about 1 to...

Ran rough now wont start
