I hope someone can help with this one. After I warm the truck up and start driving it. After a short distance if I press on the gas to speed up (on a flat surface) I hear a noise like the valves are knocking. Then the noise will stop it is about 30 seconds and after the engine light comes on. But the truck will run fine with the light on, the light stays on until I turn off the motor.
Any guesses?
