My car shuts down while driving down the freeway but only when the speed is above 80 mph. But I have changed the camshaft sensor, coil pack and ignition control module. The car does not run again for about 45 minutes. The last time it happened the code scanner told me there was random/ multiple cylinder misfire but that code didnt come up this time. The next time it did it the code said too lean bank 1. I have a 2.4L motor. What could it be?
