Both Leading Plugs. What do you think?

How many miles are on the ignition coils and spark plugs? The 2nd leading plug does not look that bad. But the 1st leading plug looks bad. Where the spark plug wires on good and in good condition?

 

Yeah Just changed the coils and plugs and wires. One of the wires was just sitting over the plug the clamp inside was broken. First time I changed them since I bought it in March 2010. Long overdue Id say.

 

Oh ok that would explain it. I bet your car drives better than it did now.

 

Big difference for sure

 

I wonder if those were stock...? Sheesh. I hope mine don't look like that when I change them.

 

I think they were man they are nasty and stink like crude oil

 

Holy cow! I don't see how those even could put off spark.

 

right I was befuddled I don't know how it was firing at all. But I have never had a cel or a misfire code. crazy i know

 

I just took mine out today and 3 plugs looked exactly like the first plug u had except with more black deposits. Found out the when the dealership said they flooded my car and "replaced the plugs" meant they just took them out and dried the gas off em. I didn't replace the plugs/coils ever when I got the car back in 2007. Figured I would take a look and the plugs came out BY HAND looking like this!

 

I replace my plugs every hmm 15K miles.

coils? it really depends, if it does not misfire I leave them alone, but I would say they last about 20K miles ?

the first plug is REALLY bad. I wonder how shitty your engine is right now, as Im sure there will be MAD carbon inside.

it might be a better idea for you to go out find a long as highway and beat the **** out of your car for at least 5-10 minutes, it will clear a lot of bad stuff away.

 

right I just wonder if they were original plugs car has 46500 the guy I bought it from is in the air force a b2 pilot so he didnt drive it much and Im the second owner. Maybe a seafoam is the ticket also

 

no point to seafoam unless you have significant problems.

just drive it hard for a bit and you'll be fine.

as for the plugs, if it does not have grooves on them, its the "original", otherwise its the "updated one"

but hmm from the pics it looks like its way overdue.
