If you have a bent valve, it would run bad all of the time. You would also hear it.
If the #1 cylender is the constant problem, have you checked to make sure the fuel injector is working properly? Also, make sure the crank sensor is clean and tight.
Check those things and let me know what you find. Also, if you have other specific questions, let me know.
