My 2010 Outlander has 113000 miles on it. I changed my NGK iridium plugs or NGK iridium IX and now I'm getting a check engine light. It seems to run just as good as it did before I change the plugs I havent been to Autozone to have code checked yet, but I have checked plugs, coils, etc. and everything is snug. Any ideas? Will go tomorrow and have code checked.

 

Could be a lot...a missed connector...a vac line...

 

CEL didn't come on til sfter changing plugs. Had a problem getting first connector to stay snapped on boot. May be a little loose but still making connection and that's why it's not missing. Gonna check there first.

 

Crank it up today and no code. Driving down the highway and seems to drive almost as good as it did before. I say almost because it seems like it lacks just a little bit of power but not enough to really notice. May just need a few miles for the plugs to get broke in. Just glad there is no code.
