Answer

Was the compression the same on all the cylinders?

Cleaning the injectors may not have been enough if the injector is failing? Try switching the injector to another cylinder and see if the misfire follows the injector.

Accepted Answer

Not always. If it is intermittent it wont as it has to misfire so many time in a period of time to trip the light so it may not be to that point yet.
