Can anyone tell me the likely problem with my 2009 Shelby GT500 that throws the code P1238? It seems to miss a little once in a while now also.
Forgot to mention this, The code translates as "Secondary Fuel System Fault" I replaced the secondary fuel system relay and went ahead and changed the fuel filter while I was at it. I cleared the code and it still seems to want to stutter every once in a while.

Re: Shelby GT500 check engine code P1238
Have not had that code before on this car. Have the fuel pressure checked.
Have had this type of code on other cars with variable speed fuel pumps. Was a bad resistor, but dont know if the Shelby works that way or not.
