in Mena, AR on March 28, 2012
CODES ARE P0300, P1310, P0300 P/D, The car shuts down at 2800 rpm. First thing in the morning it will rpm up all you want for a few minutes, then it starts shutting down. We have changed plugs, coils, maf,coolant temp, an had the converters checked. Any help would be greatly appreciated

P1310 relates to a Igniter Circuit Malfunction and P0300 is a ramdom missfire detected. The ingnition coils can cause this but you say you they have been replaced. Best thing I can reccomend is spend some money with a good technician on diagnosis. This car is equipped with variable cam timing and other things taht could set up your problem.
