SOURCE: missing on one cylinder
Replace the coil going to that cylinder, and then replace the valve cover gasket to prevent further oil from getting on the new coil. If it is not the coil, the crank sensor could have gone bad in it.

sound very much like you have an air leak problem and even a seal problem to on the intake manifold and injector seals may be leaking same happend to me on my car and i found i had to strip it all again to sort it out .
the injector seals if they are not sitting right or just a slight spec of dirt there you have a problem.
air leaks to see if you do have one use wd40 can spray on the manifold and if the engine picks up you have a leak ok
i hope this helps
let me know how you go on thanks

ignition control module, throttle position sensor and other sensors need to be tested to establish problem, any codes from OBDII ? check engine light staying on ?
