Would try a bottle of Techron in the tank and have a look at condition of injector wiring. Also re-check secure connection to spark plugs. Would get a meter and cross check ohm reading and compare. If the offending cylinder injector has a higher resistance than the others the injector may be faulty. Good Luck!
