Should you change wires and plugs together or does it matter


Recommended Posts

Im pretty sure my spark plugs are way overdue but im very short on cash right now. I can get decent plugs for 2 bucks a piece wich isint bad but the wires are expensive! Ive heard that its recommended to change both at the same time but just weondering if it matters? There is no damge (what I can see) to my current wires.

If the wires look worn i'd replace them

 

you also need to replace your ignition coils, and top them off with fluid

It's recommended that you change your blinker fluid too. It gets worn out after all that milage.

Didn't you just get a new engine? They shoulda replaced 'em then.

if your straped for cash do the plugs first then do the wires later on since they are easier to do. i'd do em both at once myself though, but if you don't got the $$ then i'd do the plugs then wires.

haha real funny

 

 

 

anyway I dont think theve ever been changed so the plugs/wires should have 100,000 miles on them. And no Im pretty sure they didnt do a plug/wire change when i got the rebuild bc its not on the bill and for sure tehy would have charged me for that.

I would change the plugs...I plan on running the original wires until i get a misfire...had bad luck with aftermarkets on my blazer...put the 120k stock ones back on and it ran like a raped ape

what are some of the signs that they are way overdue? unless your car is "acting up" then why change them?

I say you might say you might as well do it while you are doing the work...

Well ive been noticing my gas mileage getting worse and worse and people keep tellin me the plugs :shrug:

 

I got my tires balanced and everything, ran some goof fuel injector cleaner, nothing works.

Remember, winter gas sucks too..

 

With this nice weather my car feels like it has more balls for some reason.

I think it's best to change both pugs and wires at one time rather than at different times. Causes less problems and more hastle.

Well.....for the cold states....gas companies understand that the starting requirments are different when it is cold out, so they change their additive packages to match that.....helping to increase customer satisfaction (by not having a car that won't start when its 20 below because of shitty fuel).

The RVP is different. I believe in some places they add ethanol, or another additive.

Back to the plugs and wires...

 

Worn out plugs will aid you in getting shitty gas mileage, this is true...

 

I ALWAYS change plugs and wires at the same time now... My dad had always said to do them at once, but I was cheap and tried not to on a couple of cars... misfiring and such soon ensued...

 

Basically what happens is, carbon core'd wires get brittle on the inside once they've had a few heat cycles on them and don't like to move very much from where they are... A lot of people notice a misfire in top gear, going up a hill or accelorating W/O downshifting... that's bad plug wires...

 

You CAN change just the plugs, but be ABSOLUTELY SURE not to move the wires any more than you have to! They don't like being bent very much when they're old... Vibration also kills them...

That makes good sense acually :D

 

Anyway, I think im just going to wait till next week so I can get the plugs and wires at the same time.

 

I was doing some research about bad plugs and their relationship with mpg. A lot of sites said old plugs will heavely contribute to how much mpg your getting.

Posted

Ah yeah... anything that affects the efficiency of your engine will have a toll on MPG.. right down to the air in your tires.

Posted
They really put your old plugs in the new engine? :?

 

Well it wasent a full engine rebuild. They didnt go in and cahnge all the internals. Im at school right now but when I get home I can post the bill that shoes all the new shit I got.
