1996 Honda Civic CX throwing code 72 73 74

[GaGen2Teg]

Need help! searched everywhere. Codes 72,73,and 74 are random misfire.
This is the scenario...first the car was throwing code 2,41,72,73, and 74.
Then I replaced the bottom o2 sensor below the cat. Then it was just throwing code 41.
I replaced the top o2 sensor above the cat. Now its just throwing codes 72,73, and 74. And the check engine light just stays blinking.

Im clueless on what it could be. Spark plugs, Dizzy, or Wires?

reps for help!

Its blinking because its constantly misfiring. Can you not hear a skip? Check the plugs first, then do a compression test.

just my opinion but i'm going to guess plug wires. look at them and if you notice a white almost powder look in spots your losing spark to the plugs. i have also had the spark jump right before the plug, in the tube that slides into the valve cover. GL
