Question I am getting power loss when the car heats up (usually about 30min) it hesitates and eventually stalls, intermittent "check engine" and "check vehicle" lights as well as the fuel data center flashing through display modes . After checking the trouble codes I'm getting f 31 f32 ff 31 ff32. I need some help!
Answer FF31 = Fuel data center to Body computer module problem.
FF32 = Engine control module to body control module data problem.
