help my dodge ram keeps cutting out
i have a 2008 dodge ram 1500 4.7 v8 4x4 and as soon as the engine warms up it starts cutting out and jerking but there is no loud noises but it also backfires. the only codes it reads are low voltage and co2 sensors. I thought it was the fuel pump or filter cause when you park and turn it off it starts right back up and you can drive it for about 3 or 4 miles and starts all over again. and you can only go about 20 to 30 miles a hour please help.
