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.

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.

There’s no ‘break-in’ for new plugs or other ignition parts. They’re either good or they’re not. That said, I have had issues with iridium plugs in other cars. Unless the stock plugs are iridium, I don’t recommend them. Stick with stock plugs unless your engine is modified (boost, increased compression, or non-stock fuel system). Have you replaced coils too? They are susceptible to heat damage after that many years/miles. Listen for any sign of a misfire, get the code right away if it comes back. A failing coil will often get intermittent for a while as the insulation breaks down from age and heat before it fails completely.
