Emission Control Malfunction Light Came On

[Todd Piefer]

I've got a 2018 GT with just over 24K miles. I was driving in the rain today and turned right off a stop sign at the bottom of a hill out in the country and I got on it a little. I noticed that the yellow engine light illuminated. As soon as I let up, it went away. The owner's manual says it comes on when there is a malfunction of the emission control system. Any thoughts? Did I get some bad gas and a little stress made it complain?

It's just a guessing game until you're able to read the code.

The light came on and stayed on yesterday. Dealer ordered an ignition coil.

The dealer installed the ignition coil, test drove it, handed me the paperwork and sent me on my way. Two minutes later I hit the interstate and hit the throttle hard and the light came on. I took my foot off the gas and the light went off. I punched it again, and the light came back on and the engine was missing so back I went to the dealer. They said the spark plug was bad too. 90 minutes later, they didn't have a spark plug in stock and sent me home with a loaner from a local Enterprise franchise. How should I feel?

I'd feel like kicking someone in the nuts. Repeatedly.
