HELPPPP!!! spark plugs

last night I pulled my plugs out of cylinders 2 and 3, to test how bad they are, around the threads was oil which has me worried already. put everything back together with the intent of changing the plugs today.this morning ran my truck and am misfiring in at least one possibly two cylinders. any ideas??

 

Did you mix up the wires - making them fire at the wrong time?

 

checked that this morning wires are good the check engine light was coming on and the traction control light came on

 

should i go ahead and change the plugs?

 

I've read several threads where those lights come on together - I don't think that part is too big of a deal.

I'd go ahead and change them out. If the CEL light and misfire continues, then continue with the diagnosis.

 

will do! ill do that and post if that works

 

changed the plugs running much better i am going to take them out in a week to see if i am leaking oil still

 

How many miles were on the plugs you took out? Since they are copper plugs the recommended schedule is every 30k miles (assuming you have a V6)

 

i bought the truck a year ago used when i pulled them i realized they were the original plugs

 

Your not the first. How many miles were on them? I wouldn't worry too much about how the old plugs looked if they had been in there for a long time.

 

95,000

 

Damn 95,000 miles Its extremely due for new plugs. Get the irdium plugs

 

Oil on the plugs isn't a big deal. Doesn't mean your engine is shot, just that you may eventually need a new valve cover gasket. But that's on down the road. Replace your pcv valve for 10 bucks first and that may give you the relief that you need. Plugs are easy to replace once you get the hang of it. The forum is great and full of knowledgable folks.

 

just changed the plugs and original air filter on my moms 07 4 runner at 107k..... plugs were at 2x gap spec... air filter was pretty damn bad, But the thing ran great. gonna run real good now.

 

The oil is coming from leakage past the gaskets around the spark plug tubes in the valve cover. If there is any pooling of oil within the tubes around the spark plug isolators, it can cause a misfire. You might need to replace the valve cover gasket(s) before long.

 

It should not pool. There is a small hole on the side of the head from the bottom of the spark plug hole to the outside of the plug to allow any water etc to drain out of the spark plug hole.

 

all plugs have been changed no leakage yet im thinking after 95,000 miles there was a little oil and dirt that made it into the cylinders I think everything is fine

 

Glad everything is okay.
