Hello, what is the mileage of the vehicle, also have you performed a compression test?
Customer: replied 1 year ago.
About 170,000 haven't performed a compression test
Expert:  K. Wiggins replied 1 year ago.
I would suggest starting with that. Let me know what you find and we can work further.

Runs ok when cold but when it gets hot it starts sputtering like it's going to die and changing gears but won't go barely 30mph the diagnostic test at autozone said its missing on 1&3

Thanks, ***** ***** in a little different direction. Check both ignition coils when the vehicle is cold and compare them to the specs at the link below. then check them hot and compare them to each other.

Let me know what you find and we can work further if needed.
