I have a 99 Honda Accord 2.3 vtex that i need help with is started to lose power and the check engine light came on so I put it on the computer to see what codes came up 300,301,302,303 I recently changed the spark plug wires spark plugs cap and rotor I also checked the compression was fine there's anybody out there that may help me with the prom I would appreciate it

 

Are you sure you got the wires in the correct order? Are they all connected to the spark plugs correctly?

No P0304? If no P0304 then it has to be something specific to those cylinders (plugs, injectors, headgasket)

Also recheck all the work you just did.

 

It is related to the plug and wire replacement. Always look back to work you have recently done. Could be your cap and rotor. Just double check everything. If there is oil in the plug boot it will also cause misfires
