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
Why engine stalls at 2800, can't go over 40 mph on 2000 Lexus RX300
I AGREE WITH MILES

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.
Thanks, I talked to a lexus tech and he said if i used aftermarket coils that is probably my problem. I have ordered new factory ones. Thanks again. got the new coils in today problem solved
