Gentlemen.....

I have 98 Civic 360K.....I'm getting a miss-fire code on all 4 cylinders.

About a year ago I replaced:
The main relay...(the real problem)
Plugs
Wires
Cap

I just replaced the wires again, cleaned throttle body, the misfire seems a little worst at start-up.......but is fairly constant.

Any thoughts or suggestions are appreciated....

Have the distributor checked at a shop. I suggest taking it to a mechanic before you start throwing parts at it to try to fix it, a diagnosis will be cheaper in the long run.

 

I just pulled the plugs.....even though they have less than 50K on them they seem pretty worn.......for $10 I'll throw a new set in.......as soon as my wife gets home I'll fly and get some.......Standard NGK ok? or do you have a better recommendation?
