2002 Jeep Liberty 4.7l Misfiring - P0300, P0303, P0305, CAN'T FIGURE

I HAVE A JEEP LIBERTY THAT IS MISFIRING ON CYLINDERS 3 AND 5. I
REPLACED ALL SPARK PLUGS AND  REPLACED THE COILS ON #3 AND 5. STILL
SHAKES AND IDLES ROUGH. ACTS LIKE NOTHING WAS REPLACED AND CHECK
ENGINE LIGHT FLASHES WHILE DRIVING OR IDLING. FLASHES 10 TIMES AND
THEN PAUSES FOR A FEW SECONDS REPEDELY, THEN SOMETIMES IT RUNS OK AND
HAS A SLIGHT MISFIRE AND THE CHECK ENGINE LIGHT RETURNS, CANNOT
COMPRESS THE GAS PEDALPAST HALF WAY OR VEHICLE WILL CUT OUT AND REV
LIMITER KICKS IN. WHAT COULD THIS ISSUE BE? CLOGGED FUEL INJECTORS?
FAULTY WIRING TO COIL? CAN ANYONE RELATE TO THIS ISSUE?
