Toyota Repair: Misfire 1-4-5, obdii, toyota dealer


Question
OBDII P1300 P0300 P0301 P0304 P0305

This has happened now twice to me. I will be returning home after about 40-80 mile trip, mostly freeway driving 70 to 75, and I have to stop at a traffic light and the truck dies. I restart it and drive home no problems, drive the whole week to work 10 miles no problems. I hook up an OBDII tool and it pulls these codes. I have taken the truck to the local Toyota dealer hoping they could fix it, but after $850 still nothing, they replaced the ignitor. Does anyone know what it could be or what I can start looking at. I have replaced the plugs with NGK, and the wires with the highest grade NAPA sold. I thought it was a Coil but it doesn't match that problem. Truck has 112000 miles.

Answer
I have run into misfire codes that were not related to coils or wires etc. after making sure that the compression is good I found that a lot of times at this mileage there is a problem with the fuel injectors, they may intermittently not work correctly and give these codes.
