I have a 3.1 l v6 chevy lumina ive replaced the map sensor acv
nd the maf sensor also the throttle position sensor. The reason these were replaced was because the car had stalled while my daughter was driving and these were the codes that came up when scanned after being replaced the car ran fine for about a week and stalled again. Now the only way to get it to run is sptay carb cleaner into the intake. Which the car fires and runs sluggish and only for a few seconds. What would be causing this problem please help this is the vehicle that my. Daughter uses to get to school and work.
