so i was wondering how do i know if i should change my spark plug wires? some symptoms? thanks

 

anyone?

 

idk how you can check wires other than the spark plug simply not firing.

 

cause sometimes it doesnt wanna start up rite away...and my gas millage sucks..

 

when you rev it, or sometimes at idle. is smoke coming from your exhaust? if its blue or white one of those, i believe some fuel isnt getting burnt, so you might be misfiring, but you would get a CEL for that.

if your getting bad mpg, it just may be time for a full tune up anyways

 

well are u always getting a spark? cause if u arent getting a spark it might be more than just ur wires/plugs

 

you can use a digital multimeter and check the resistance in the wire. just stick one lead from the meter to one end of the wire and the other lead to the other end. make sure your meter's on ohms. the reading should be rather low. you can get a cheap multimeter at most hardware stores

 

no smoke..no CELs...it doesnt do it all the time..just 2 out f 10 times i would say..and it idles really low..like 700-800...

 

when it idles does it bog down like its not getting enough fuel?

 

no like its at 1k then it goes down slowly and it just stays there..sometimes i think its going to shut off but it never does..

 

go outside when its dark and mist a little water on the wires start it up and see if you see any sparks they will be blue, I knew mine needed to be changed when I touched them while my car was running and got shocked...lol

 

have u adjusted your idle screw to fix the idle problem

 

^^^ no i havent...i dont know where that screw is...and wat way should i turn it to make it idle higher? counter clock wise or clock wise?

 

check the resistence in the wires, if is more than 25 ohms change thy

 

the idle screw is on your throttle body, turn your car on and turn the screw both ways and see which works, i cant remember off the top of my head which way.

 

^ Or run the car and listen to the idle. Then with the car still running, mist water on the wires and listen for an idle change. If there's a change in the idle, then the wires are bad.

thecruzs2007 - I wouldn't mess with the idle screw until you check for other problems first. If you play with the idle screw first, and then later on fix the real issue, your idle is going to be off from adjusting it.

 

last time i check this isnt a carburetor civic the iacv will just re adjust it back into the same spot.. check your plugs they are the man-ly version of using your own dignostics. if they are saturated in gas your not sparking. how old are your wires

 

700-800..... isn't that what it's supposed to idle at or around it??

 

almost 900
