so i've had this some up a couple times now, i posted back in late july reguarding this, only when im driving with the cruise set at 65-70 mph. the light comes on and for a split second the motor hick-ups or stops and then keeps going. no significant power loss or anything. but it does seem a little slower (over the past couple months) my edge says it a code, PO251 CP3 Pump Regulator Control. is this something i can fix easy? or should i bring it in? all i have is whats in my sig. thanks

nobody knows anything..??

 

It is the FCA.

Could have a bad injector too.

Fuel control actuator,it bolts on to the rear of the injection pump.It controls the amt of fuel allowed to enter the pumping chambers
