so i have a 1998 honda civiC MT
it threw a CEL and i checked it looked up the code and corresponded with a random misfire cylinder 4 any suggestion on how to go about fixing this? what should i check replace? thanks

 

any help??

 

Could be a few things like, spark plugs, plug wires, leaky head gasket.....etc

 

It could be the #4 spark plug is bad. Cylinder #4 is the right most spark plug hole on the valve cover. It could be the #4 spark plug wire. Replace both of them and I'm sure it will fix the problem.

 

ok thanks i will check spark plug and replace.. is there a way to chek the wires or should i just replace?

 

Yes there is, pull the wire completly of the motor and just look at it to see if there is any white spots or tears, on the boot or wire itself. If there are, the spark might be arcing through the boot or wire to something else. If so, just replace it. It is also best to replace all 4 at the same time though.

 

k cool will chek em out and most likely replace them... kinda of topic but will the cel reset on its own or do i have to reset the ecu

 

You have to reset the CEL.

 

If you don't have access to a scanner that can clear codes you can always disconnect your battery for about 10 minutes and that will do the trick.

 

k thanks for the info

 

Hey im new here but try and clean the EGR port if it is not the plug

 

the EGR won't make it misfire though

 

well my h22 prelude had a random misfire and it was the EGR.But if you dont think its that.Then start with a wire,plug,cap. Hope i helped.

 

The egr will and could make it misfire

 

chnage all the spark plugs and wires first
