Greetings! . . . and a question

Greetings! I just brought home my 2014 JK Unlimited Sahara edition, and I love it! This is my second Jeep . . I had a Wrangler Sahara back in 2000 briefly, and I've missed Jeepdom since!

So, this morning, I cranked up the Jeep for a family ride to go get lunch, and the check engine light was on, and I was getting a system tone. The ride was really sluggish with a lot of vibration in the gear shift. I drove it home immediately, and we took my wife's car.

When I got back, I checked the gas cap . . removed it and put it back on securely and let it click a couple of times. The Jeep has since performed just fine, but the check engine light is still on, and I can't get the Jeep to show me I'm in "ECO" mode, regardless of the RPM of the vehicle.

I *think* the issue is that when the sales guy filled up the car yesterday, he didn't secure the gas cap properly, and I proceeded to put 80 miles on it without a good seal going to the tank. I've seen this before with other vehicles, and I've seen the check engine light take quite a few miles to finally go away. Still, I'm concerned that nothing I do will show the ECO indicator . . so I'm wondering if there might be something else.

Have you guys seen this kind of thing before? I'm otherwise really loving the Jeep . . have about 150 miles on it, and I've enjoyed each one.

Having the gas cap loose or off won't cause it to be sluggish. It'll still drive normal. Would check too see what codes you have & you can clear them.
