While driving slow, turning or taking off even stopping the car keeps stalling and then the dash message shows "speed limited to 140" I am not speeding or driving fast I am actually only doing 10 mph or idling. The car doesn't stall when driving fast. There are no codes or dash lights except a code for the brake pedal when checked by local car part store computer.
Its a 2007 impala v6 3.9L police with 225k miles.
Can anyone tell me what to check next? I am thinking maybe tps sensor or ecm next? I have replaced the speed sensor.
The ac also cuts off sometimes and blows hot air and when i push the power window up or down button it seems like the there might be a power issue because the ac seems to act like it wants to cut off when i roll the window up or down. I dont know if this is related or means anything but i thought I would mention it.
I replaced the speed sensor, water pump, oil pressure sensor, idle pully, spark plugs, fuel injection has been cleaned, throttle body has been cleaned, mass air flow sensor has been cleaned, oil change radiator flush, new drive belt, fixed o2 sensor rear exhaust and exhaust pipe damage. Just trying to be thorough.
